Abstract

The invention relates to the technical field of bearing retainers and discloses a cylindrical roller bearing retainer with double locking ports, and an assembling method. The cylindrical roller bearing retainer with the double locking ports comprises a frame body 1, whole pocket holes 2 and double-row locking points, wherein the plurality of whole pocket holes 2 are uniformly formed in the inner diameter of the frame body 1; one double-row locking point is arranged on each whole pocket hole 2 of the inner diameter of the frame body 1. According to the cylindrical roller bearing retainer with the double locking ports, a rolling body can be prevented from being inclined in the rotating process and a blocking condition is prevented so as to recover the loss of enterprises. Therefore, the stable operation of the rolling body can be guided well, the operation stability of a bearing is improved, the service life of the bearing is prolonged and the cylindrical roller bearing retainer is very worthy of being popularized and applied.

Description

A kind of roller bearing retainer and assembly method with twin-lock mouth

Technical field

The present invention relates to bearing cage technical field, relate in particular to a kind of roller bearing retainer and assembly method with twin-lock mouth.

Background technique

At present, on large-scale Biserial cylindrical roller bearing, the application of double claw type retainer is very general, sees Fig. 1; This retainer manufacturing procedure is simple, and cost is lower.But the structure that the drawback of this retainer is exactly the beam of retainer is the structure of an overhang, in stressed larger occasion, retainer is easy to damage.This retainer guiding rolling element is not whole guiding in addition, when the slenderness ratio of rolling element surpasses, sees the double claw type retainer of the original structure of Fig. 2, can find out that the beam in the middle of pocket hole is overhang 3, and the root of beam is stressed larger, the easy bending distortion of retainer; Be easy to occur stuck phenomenon ，Gei enterprise and cause damage when bearing rotary, be therefore necessary existing retainer structure to improve.

Summary of the invention

In order to overcome the deficiency in background technique, the invention provides a kind of roller bearing retainer and assembly method with twin-lock mouth.

In order to realize foregoing invention object, the present invention adopts technological scheme as follows:

A kind of roller bearing retainer with twin-lock mouth, comprise: support body 1, whole pocket hole 2, double lock point, the internal diameter of described guarantor's support body 1 is evenly equipped with some whole pockets hole 2, and on each whole pocket hole 2 of the internal diameter of support body 1, be provided with a double lock point, described double lock point consists of the lock point 2.1 that is distributed in every row on long limit, 2 two, hole of the integrally-built whole pocket of rectangular; On each long limit, every row's lock point 2.1 is two lock points.

A roller bearing retainer for twin-lock mouth, the step hole structure that described every row's lock point 2.1 is rectangle.

An assembly method for the roller bearing retainer of twin-lock mouth, its step is as follows:

1, in the integrally-built whole pocket of the some rectangulars of the uniform processing of the internal diameter hole 2 of support body 1, and on the internal diameter of support body 3, on two long limits in the integrally-built whole pocket of rectangular hole 2, mill out two lock points 2.1 of every row;

2, the hold depth of retainer fore shaft 1 is arranged between 0.1 ~ 0.3mm according to bearing size and rolling element size;

While 3, assembling, be from support body 1 internal diameter direction, rolling element to be packed in the integrally-built whole pocket of rectangular hole 2, in the time of can avoiding rolling element rotation, crooked and stuck situation occur and occur, thereby better guide the steady of rolling element rotation.

Owing to adopting technological scheme as above, the present invention has following superiority:

A kind of roller bearing retainer and assembly method with twin-lock mouth, employing is provided with the integrally-built whole pocket of a rectangular hole on the internal diameter of support body 1, on each whole pocket hole of internal diameter, adopt double lock point, can better avoid like this rolling element when rotation to occur crooked, thereby better guide rolling element.Retainer makes into after this structure, and rolling element has not been retrieved loss because ，Gei enterprise occurs the bad stuck situation of guiding again.This double lock is put whole pocket hole retainer, can better guide rolling element, has improved the stationarity of bearing operation, has extended the working life of bearing, is worthy of popularization very much.

Fig. 2 be Fig. 1 A-A to structural representation;

Fig. 3 is the structural representation with the roller bearing retainer of twin-lock mouth;

Fig. 4 is the plan structure schematic diagram of Fig. 3;

Fig. 5 be Fig. 3 A-A to lock dot structure schematic diagram;

In figure: support body 1, whole pocket hole 2, lock point 2.1, overhang 3;

[embodiment]

As shown in Figure 1, 2, a kind of roller bearing retainer with twin-lock mouth, comprise: support body 1, whole pocket hole 2, double lock point, the internal diameter of described guarantor's support body 1 is evenly equipped with some whole pockets hole 2, and on each whole pocket hole 2 of the internal diameter of support body 1, be provided with a double lock point, described double lock point consists of the lock point 2.1 that is distributed in every row on long limit, 2 two, hole of the integrally-built whole pocket of rectangular; On each long limit, every row's lock point 2.1 is two lock points.

This is adopted as rectangular integrally-built whole pocket hole 2 with the roller bearing retainer of twin-lock mouth, is above provided with double lock point, can better avoid like this rolling element when rotation to occur crooked, thereby better guide rolling element.Retainer makes into after this structure, and rolling element has not been retrieved loss because ，Gei enterprise occurs the bad stuck situation of guiding again.

Claims

1. the roller bearing retainer with twin-lock mouth, it is characterized in that: comprising: support body 1, whole pocket hole 2, double lock point, the internal diameter of described guarantor's support body 1 is evenly equipped with some whole pockets hole 2, and on each whole pocket hole 2 of the internal diameter of support body 1, be provided with a double lock point, described double lock point consists of the lock point 2.1 that is distributed in every row on long limit, 2 two, hole of the integrally-built whole pocket of rectangular; Every row on each long limit locks a little 2.1 and is two and locks points.

2. a kind of roller bearing retainer with twin-lock mouth according to claim 1, is characterized in that: described every row's lock point 2.1 is the step hole structure of rectangle.
