Abstract

The invention relates to a method for the manufacture of a plastic component such as a seal (1) for a roller bearing. Hereby first the soft sealing part (2) is formed and then the supporting part (3). The heat from the molten plastic which is going to form the supporting part (3) will melt the surface of the sealing part (2) adjacent to the supporting part (3). This ensures that both parts bond well to each other. The invention also relates to a mould for executing the method and to a roller bearing provided with a plastic component which is formed by applying the method according to the invention.

Description

A method for the manufacture of a roller bearing component comprising plastic, a roller bearing provided with such a plastic component and a mould for the application of the method
The present invention relates to a method for the manufacture of a roller bearing component comprising plastic, which component is provided with sealing part comprising a thermoplastic first plastic and a supporting part, comprising a second plastic.
Such a method is known. In said method a supporting part is introduced into the mould, which supporting part is formed of plastic or metal, after which a sealing part is formed from thermoplastic plastic. Application of the plastic may be carried out by means of, for instance, an injection- moulding technique.
This method has the disadvantage that the bonding of the sealing part to the supporting part leaves something to be desired. For instance when using oil for the lubrication of a roller bearing, oil molecules, in particular the smaller ones, will force themselves between the two parts causing deterio¬ ration of the bonding. Changes in temperature and vibrations during operation also have a detrimental effect on the bonding of the sealing part to the supporting part. It is the object of the present invention to elimin¬ ate the above-mentioned disadvantages and to provide a roller bearing component comprising plastic which exhibits better bonding under taxing conditions.
To this end the method according to the invention is characterized in that for the first and second plastic compat¬ ible plastics are used, whereby first the thermoplastic seal¬ ing part is formed in a mould and then the supporting part is formed, whereby heat from the supporting part will at least partly melt the thermoplastic part thereby forming a bonding zone, after which the seal is allowed to cool to below the melting point of the thermoplastic plastic and the material in the bonding zone. Thus it is prevented that polymer chains of the plas¬ tic are present in a fixed position at the surface of a plas¬ tic part, in particular the supporting part, unable to adapt to the new environment at the boundary surface. With the method according to the invention the polymer chains near the surface reach a molten state and adapt to the new situation. This ensures a better bonding. Depending on the type of first and second plastic used, mixing may occur which is also advan¬ tageous for bonding. Even small lubricant molecules cannot force themselves between the first and second plastic, with the result that a plastic component made according to the method of the invention is more resistant to lubricants.
A preferred embodiment of the method according to the invention is characterized in that the thermoplastic sealing part is formed such that while forming the supporting part, a portion of the sealing part is incorporated in the supporting part.
By means of the incorporation the thermoplastic seal¬ ing part is surrounded by the supporting part which promotes heat being transferred to the sealing part. This furthers the strength of the bonding between the two parts. Furthermore, a plastic component formed in this manner is better able to resist forces not only in radial direction but also in axial and tangential direction. According to another embodiment the method according to the invention is characterized in that, while forming the supporting part, a mould is used which promotes the conveyance of heat from the supporting part to the sealing part.
With techniques of injection moulding one generally uses a metal mould through which the heat is quickly conveyed, allowing for fast manufacture of the product to be formed. With a mould according to the invention enough heat energy flows from the supporting part to the sealing part so that this sealing part melts at least in part. This ensures good bonding.
The invention also relates to a roller bearing pro¬ vided with a seal, characterized in that the seal is manufac¬ tured using a method according to the invention. The invention will now be elucidated by means of the drawing, explaining the invention by way of example.
Fig. 1 is a top view of a roller bearing seal.
Fig. 1 is a cross-section according to the line II-II from Fig. 1.
Fig. 3 is a detail from Fig. 2.
Fig. 4 and 5 show a partial cross-section of a mould with a seal.
The seal 1 for a roller bearing shown in Fig. 1 com- prises a sealing part 2a, 2b and a supporting part 3. Accord¬ ing to the invention such a seal 1, being a roller bearing component comprising plastic, is formed by first forming the thermoplastic sealing part 2 in a mould and then the suppor¬ ting part 3, whereby heat from the supporting part 3 at least partly melts the thermoplastic sealing part 2, thereby forming a bonding zone 4, after which the seal 1 is allowed to cool to below the melting point of the thermoplastic plastic of the sealing part 2 and the material in the bonding zone 4. Partly melting of the thermoplastic sealing part 2 causes the polymer molecules at the surface of the sealing part 2 and facing the supporting part 3, to reorientate themselves in order to adapt to the new environment which is formed by the second plastic of the supporting part 2. It is possible that mixing of the first plastic and the second plastic occurs in the thus formed bonding zone 4, which furthers good bonding.
For the supporting part 3 preferably a thermoplastic second plastic is used having a higher melting point than that of the sealing part 2. In this way much energy in the form of heat is available during the manufacture of seal 1 to partly melt the first plastic of the sealing part 2.
The sealing part 2 is preferably formed from polyur- ethane, such as thermoplastic polyurethane melting at 180- 195°C, and the supporting part from nylon, such as Nylon 6.6 melting, for instance, at 340°C. For example, first a sealing part 2 is formed by maintaining the mould 6 at 70°C and to provide it with a thermoplastic polyurethane which melts at 180-195°C. Subsequently, also by means of injection moulding, polyamide 6.6 having a melting point of 340°C is introduced into the mould 6 which is heated to 120°C. The polyamide at least partly melts the thermoplastic polyur-ethane, giving the desired good bonding.
To promote the bonding between the sealing part 2 and the supporting part 3 the thermoplastic sealing part 2 is pre- ferably formed such that a part of this sealing part 2 which is to be incorporated into the supporting part 3 is provided with surface-enlarging structures. A larger surface promotes bonding. The part incorporated into the supporting part 3 is preferably formed in such a way that it becomes wider towards the supporting part 3. This is shown in Fig. 3 and provides extra strength for the attachment between the supporting part 3 and the sealing part 2.
According to an advantageous embodiment the suppor¬ ting part 3 is formed from fibre-containing plastic and at least part of the fibres possess a surface which is compatible with the thermoplastic plastic of the sealing part 2. This allows fibres and thermoplastic plastic coming into contact with each other to bond well.
In order to melt the first plastic of the thermoplas- tic sealing part 2, sufficient heat is required. It will be obvious that certain geometries such as the rim 5 shown in Fig. 3, will not have sufficient heat capacity, especially near the edge of the rim 5, to melt the first plastic of the sealing part 2. For this reason it is preferable to slow down the fast heat dissipation of the plastic to the metal mould 6, which will raise the temperature of the sealing part 2, par¬ ticularly in its bonding zone 4. In this way the contact in the contact zone between the sealing part 2 and the supporting part 3 will lead to proper bonding, whereby the entire contact zone becomes the bonding zone 4.
According to a preferred embodiment a mould 6 is applied which is formed from a material having a low thermal conduction coefficient or which is provided with such a coat¬ ing 7. In order to avoid deterioration of the production process it is not necessary to make the whole mould 6 from a material having a low thermal conduction coefficient but it suffices that the heat dissipation is slowed down enough to allow the contact zone to warm up sufficiently to melt the first plastic over the entire contact zone. According to a suitable embodiment the mould used, being made from material having a low thermal conduction coefficient or being provided with such a coating 7, is at least near the contact zone pro- vided with a coating 8 having a higher thermal conduction coefficient. This promotes the desired heating of the contact zone. The coatings having low and high thermal conduction coe¬ fficients 7,8 need not extend over the entire inner surface of a mould 6, as shown in Fig. 5. The invention further relates to a roller bearing provided with a cage, characterized in that the cage which is provided with a sealing part 2 is formed by a method according to the invention. In this manner, in one process run, a compo¬ nent for a roller bearing can be formed serving various pur- poses, namely retaining roller bearings and screening the inside of the roller bearing against the environment.
The present invention also relates to a mould for the manufacture- of a plastic component for a roller bearing. Such a method is characterized in that the mould 6 is formed from a material having a low thermal conduction coefficient or which is provided with a coating made from such a material 7. Accor¬ ding to an advantageous embodiment the mould 6 is character¬ ized in that the mould 6 having a low thermal conduction coef¬ ficient or being provided with a coating made from such a material 7 is, at least near the bonding zone 4, provided with a coating made from material having a high thermal conduction coefficient 8.
Clearly, for the manufacture of the mould different mould parameter settings must be applied such as the thickness of the coating with a low thermal conduction coefficient, and that these depend upon parameters such as the heat capacities of the plastics used and the thickness of the component com¬ prising plastic. A person skilled in the art can determine suitable values to ensure that the entire contact zone func- tions as bonding zone 4.
