Abstract
The utility model discloses a combined bearing for an axle main speed reducer. The small retaining side of a top bearing internal ring of a top bearing and the small retaining side of a tail bearing internal ring of a tail bearing are arranged oppositely; both the small retaining side of the top bearing internal ring and the small retaining side of the tail bearing internal ring extend outwards; the extension part of the small retaining side of the top bearing internal ring is provided with a top retaining side groove, and the extension part of the small retaining side of the tail bearing internal ring is provided with a tail retaining side groove; and the top retaining side groove and the tail retaining side groove are internally clamped and connected with an M-shaped spring to connect the top bearing with the tail bearing. The combined bearing for the axle main speed reducer has simple structure, and totally omits a plurality of insulation sleeves in the original structure, thereby greatly simplifying the structure of the bearings and reducing the number of parts; and the M-shaped spring has the following two functions: connecting the two bearings together and automatically adjusting the pre-tightening force of the bearings by utilizing the elastic deformation of the M-shaped spring.
Description
Technical field
The utility model belongs to a kind of combination bearing, particularly a kind of vehicle bridge main reducing gear combination bearing.
Background technique
In original main reducing gear structure, a separation sleeve is arranged between the two bearings inner ring, the separation sleeve width need be divided into some groups during the main reducing gear assembling, when pretightening force does not meet the demands, just need to change separation sleeve, adjust very trouble.Because a plurality of assemblies are formed, so the axial carrying capacity of this bearing also can't reach usage requirement.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, is convenient to the vehicle bridge main reducing gear combination bearing of the adjustment of pretightening force.
To achieve these goals, the technological scheme that the utility model is taked is: a kind of vehicle bridge main reducing gear combination bearing, form by top bearing and tail bearing, the all relative setting of the little rib of tail bearing inner ring of the little rib of top bearing inner race of described top bearing 5 and tail bearing 1, little rib of described top bearing inner race and the equal extend outwards of the little rib of tail bearing inner ring, the prolongation of the little rib of top bearing inner race is provided with top rib groove 4, the prolongation of the little rib of tail bearing inner ring is provided with afterbody rib groove 2, is connected with M type spring 3 in described top rib groove 4 and the afterbody rib groove 2 top bearing 5 is connected with tail bearing 1.
Vehicle bridge main reducing gear combination bearing described in the utility model, simple in structure, the some separation sleeves in the original structure are all saved, simplified the structure of bearing greatly, reduced the quantity of part.And M type spring has two effects, the one, two bearings is linked together, and the 2nd, can utilize the resiliently deformable self-adjustable bearing pretightening force of M type spring.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.
Embodiment
As shown in Figure 1, the little rib of top bearing inner race of the top bearing 5 of this vehicle bridge main reducing gear usefulness combination bearing and all relative setting of the little rib of tail bearing inner ring of tail bearing 1, little rib of described top bearing inner race and the equal extend outwards of the little rib of tail bearing inner ring, the prolongation of the little rib of top bearing inner race is provided with top rib groove 4, the prolongation of the little rib of tail bearing inner ring is provided with afterbody rib groove 2, is connected with M type spring 3 in described top rib groove 4 and the afterbody rib groove 2 top bearing 5 is connected with tail bearing 1.
Claims (1)
