Abstract
The utility model relates to an assembling device used to mount four angle-contacts bearing for electrical motor, particularly relates to an assembling unit used for a four angle-contacts bearing, which solves quality problem of prior arts that axial internal clearance of four angle-contacts bearing deviates regulated value after mounted the bearing. The utility model consists of a pressing plate connecting with end of rotating shaft of motor, a shaft lining cased on the pressing plate and pressed on an inner ring through its edges, bolts inserted into the pressing plate after pass through the shaft lining, an oil cylinder of center hole cased between hexagonal head of bolt and the shaft lining. With the design that an oil cylinder of center hole is cased on the screw, the assembling device of the four angle-contacts bearing enables the shaft lining to be subjected to symmetrical compressive forces produced by the hydraulic oil cylinder, thereby, inner body and outer body of the inner ring are equally pushed and moved by the shaft lining so as to reinforce compressive force and fastening. Therefore, the axial clearance of the bearing between the inner and outer body of the inner ring achieves design standard.
Description
Technical field
The utility model relates to a kind of 4 angular contact bearing assembling devices that are applied to motor, is specially a kind of 4 angular contact bearing assemblers.
Background technology
As schematically shown in Figure 1, lateral body 7, outer lateral body 6 in the inner ring that is installed in 4 angular contact bearings 1 of various middle and small motor rotary shaft end is divided into.In traditional assembling process, last is installed to the outer lateral body 6 of inner ring in the rotating shaft, be easy to produce gap or inclination between the interior lateral body 7 of inner ring and the outer lateral body 6, cause the motor assembling can not satisfy the end-play of drawing requirement, influence the runnability of motor.The interior lateral body 7 of existing installation inner ring, the device of outer lateral body 6 comprise axle sleeve 2 and bolt 4, and pressing plate 3, the axle sleeve diameter is suitable with outer lateral body, drives axle sleeve 2 by manpower rotating bolt 4 and is taken up in order of priority the interior lateral body of promotion, outer lateral body inwardly to move, and outer lateral body and interior lateral body are combined closely.Yet this assembling device can only apply power to axle sleeve with manpower, so can occur because of the bearing phenomenon of cover partially appears in unbalance stress, the result causes 4 overproof quality problems of angular contact bearing assembling rear bearing end-play.
Summary of the invention
The utility model provides a kind of 4 angular contact bearing assemblers in order to solve 4 angular contact bearing assembling overproof quality problems of rear bearing end-play that exist in the prior art.
The utility model is realized by following technical scheme, a kind of 4 angular contact bearing assemblers, comprise the pressing plate that is connected with the machine shaft end, be enclosed within on the pressing plate and the edge is pressed on the axle sleeve of inner ring, pass the bolt that axle sleeve inserts pressing plate, six square toes on the bolt and the part between the axle sleeve are with the centre bore oil cylinder.
Work and use are, the interior lateral body or the outer lateral body of 4 angular contact bearing inner rings are enclosed within the rotating shaft of motor, then pressing plate is fixed on the rotating shaft end, again axle sleeve is enclosed within the rotating shaft end and be pressed on lateral body or the outer lateral body, simultaneously screw rod is connected with pressing plate, start the centre bore oil cylinder then, the piston rod of centre bore oil cylinder is that the interior lateral body of impeller-hub cover compressing inner ring reaches definite position, and then the outer lateral body of compressing inner ring body is close to the inside.
Compared with prior art, the utility model is the design of suit centre bore oil cylinder again on the screw rod of existing 4 angular contact bearing assembling devices, can make axle sleeve be subjected to the pressure of uniform hydraulic jack, axle sleeve is passed uniformly to the interior lateral body of inner ring, the generation of outer lateral body respectively, and it is fastening to pressurize.So can make the end-play of two body intermediate bearings of bearing inner race reach design standard.

4 angular contact bearings of 1-among the figure, 2-axle sleeve, 3-pressing plate, 4-bolt, 5-centre bore oil cylinder, the outer lateral body of 6-, lateral body in the 7-
The specific embodiment
Anticipate as shown in Figure 2, a kind of 4 angular contact bearing assemblers comprise the pressing plate 3 that is connected with the machine shaft end, are enclosed within on the pressing plate 3 and the edge is pressed on the axle sleeve 2 of inner ring, pass the bolt 4 that axle sleeve 2 inserts pressing plate 3, six square toes on the bolt 4 and the part between the axle sleeve 2 are with centre bore oil cylinder 5.
Claims (1)
1. 4 angular contact bearing assemblers, comprise the pressing plate (3) that is connected with the machine shaft end, be enclosed within that pressing plate (3) is gone up and the edge is pressed on the axle sleeve (2) of inner ring, pass the bolt (4) that axle sleeve (2) inserts pressing plate (3), it is characterized in that: the part between six square toes on the bolt (4) and the axle sleeve (2) is with centre bore oil cylinder (5)
