Abstract
The invention relates to the technical field of bearing retainer, and discloses a double-claw cylindrical roller bearing retainer with a lock opening and an assembly method thereof. The double-claw cylindrical roller bearing retainer comprises a cage lock opening 1, cage pockets 2, and a cage body 3. A plurality of the cage pockets 2 are uniformly distributed on the inner diameter of a cage body 3, and the cage lock opening 1 is arranged on the inner diameter of the cage body 3. The invention assists in solving an assembly problem of a cylindrical roller bearing with seals on both ends. With the bearing, the rolling bodies can be smoothly assembled into the pockets, and are prevented from falling from the pockets due to self weights. A defect of milling notches at a barrier wall is avoided. A sealed structure of the bearing can be easily realized, and processing and assembly are convenient.
Description
Technical field
The present invention relates to the bearing cage technical field, relate in particular to a kind of roller bearing of the double claw type with fore shaft retainer and assembly method.
Background technique
At present, existing double claw type cylindrical bearing retainer, when the dress rolling element, be all in the pocket hole of axially packing into of retainer, like this for the roller bearing with rib, must on rib, mill a suitable breach, could be when assembling, by rolling element from indentation, there from the retainer pocket hole of axially packing into, for not with the roller bearing of sealing, this assembly method is feasible.But, for the roller bearing of two ends band sealing, if still mill a breach on end face while assembling, will cause existing sealing not have effect.In view of above reason, existing double claw type retainer structure needs to improve.
Summary of the invention
In order to overcome the deficiency in background technique, the invention provides a kind of roller bearing of the double claw type with fore shaft retainer and assembly method, increase the working life of above time of twice than common bearing cage.
In order to realize the foregoing invention purpose, the present invention adopts technological scheme as follows:
A kind of roller bearing of the double claw type with fore shaft retainer comprises: retainer fore shaft 1, retainer pocket hole 2, support body 3, the internal diameter of described guarantor's support body 3 is evenly equipped with some retainer pockets hole 2, and is provided with a retainer fore shaft 1 on the internal diameter of support body 3.
A kind of assembly method of the roller bearing of the double claw type with fore shaft retainer, its step is as follows:
1, in the some retainer pockets of the uniform processing of the internal diameter of support body 3 hole 2, and mill out a retainer fore shaft 1 on the internal diameter of support body 3;
2, the hold depth of retainer fore shaft 1 is arranged between 0.1 ~ 0.3mm according to bearing size and rolling element size;
3, the assembling of the roller bearing of retainer and the sealing of two ends band, by the retainer fore shaft 1 of support body 3 internal diameters and the roller bearing assembling of two ends band sealing, during assembling, in rolling element being packed into to the pocket hole of retainer from support body 3 internal diameter directions, avoided milling at rib the drawback of breach, be convenient to bearing and realize sealing configuration, and processing and assembling is convenient.
Owing to adopting technological scheme as above, the present invention has following superiority:
A kind of roller bearing of the double claw type with fore shaft retainer and assembly method can radially be put into rolling element in the pocket hole from retainer when assembling, have solved the assembly problem of the roller bearing of two ends band sealings.While assembling via fore shaft from the support body internal diameter, the physical efficiency that can guarantee the to roll pocket hole of packing into smoothly, can guarantee that again rolling element does not drop out from the pocket hole under the self gravitation effect.
[accompanying drawing explanation]
Fig. 1 is the structural representation with the double claw type roller bearing retainer of fore shaft;
Fig. 2 be Fig. 1 A-A to structural representation;
In figure: retainer fore shaft 1, pocket hole 2, support body 3;
[embodiment]
As shown in Figure 1, 2, a kind of roller bearing of the double claw type with fore shaft retainer, comprise: retainer fore shaft 1, retainer pocket hole 2, support body 3, the internal diameter of described guarantor's support body 3 is evenly equipped with some retainer pockets hole 2, and is provided with a retainer fore shaft 1 on the internal diameter of support body 3.
A kind of assembly method of the roller bearing of the double claw type with fore shaft retainer, its step is as follows:
1, in the some retainer pockets of the uniform processing of the internal diameter of support body 3 hole 2, and mill out a retainer fore shaft 1 on the internal diameter of support body 3;
2, the hold depth of retainer fore shaft 1 is arranged between 0.1 ~ 0.3mm according to bearing size and rolling element size;
3, the assembling of the roller bearing of retainer and the sealing of two ends band, by the retainer fore shaft 1 of support body 3 internal diameters and the roller bearing assembling of two ends band sealing, during assembling, in rolling element being packed into to the pocket hole of retainer from support body 3 internal diameter directions, avoided milling at rib the drawback of breach, be convenient to bearing and realize sealing configuration, and processing and assembling is convenient.
