Abstract
The utility model discloses a conveniently adjusting structure for a motor bearing clearance. The adjusting structure comprises a motor shaft, a front bearing, a back bearing, a front end cover, a back end cover, a front bearing press cover and a back bearing press cover. The front bearing and the back bearing are respectively embedded in the inner holes of the front end cover and the back end cover. The inner rings of the front bearing and the back bearing are in interference fit and sleeve the two ends of the shaft shoulder of the motor shaft. The right end surface of the front bearing press cover is contacted with the left end surface of the outer ring of the front bearing. The right end surface of the back bearing is spaced from the left end surface of the back bearing press cover. A clearance adjusting device is disposed between the right end surface of the back bearing and the left end surface of the back bearing press cover. The adjusting structure makes further improvements in that the clearance adjusting device comprises a press plate and an adjusting screw. The adjusting screw is threadingly connected to the press plate. The end part of the adjusting screw is abutted against the press plate. The adjusting structure can adjust the axial clearance between the motor bearings with convenience, efficiency and simple operation.
Description
Technical field
The utility model relates to a kind of bearing axial clearance and adjusts structure, and more particularly, the utility model relates to a kind of bearing of motor end play and adjusts structure.
Background technology
Existing bearing of motor supporting structure generally comprises motor shaft, front end bearing, rear end bearing, front end housing, rear end cap, front end bearing gland, rear end bearing gland; Described front end bearing, rear end bearing outer ring are inlaid in respectively in front end housing, rear end cap endoporus, front end bearing, rear end bearing inner ring interference fit are sleeved on the two ends of the motor shaft shaft shoulder, front end bearing gland right side contacts with front end bearing outer ring left side, between rear end bearing right side and rear end bearing gland left side, leave gap, gap length by arranging pad adjustment between rear end bearing gland and rear end cap connecting end surface.This adjustment is relatively simple for structure, but each adjustment need be pulled down rear end bearing gland, changes the pad of different-thickness, bothersome, time-consuming, cumbersome.
Summary of the invention
The utility model, for the deficiencies in the prior art, provides a kind of bearing of motor gap convenient regulating type structure that can adjust easily bearing of motor end play.
The utility model is achieved through the following technical solutions technical goal.
Bearing of motor gap convenient regulating type structure, comprises motor shaft, front end bearing, rear end bearing, front end housing, rear end cap, front end bearing gland, rear end bearing gland; Described front end bearing, rear end bearing outer ring are inlaid in respectively in front end housing, rear end cap endoporus; Described front end bearing, rear end bearing inner ring interference fit are sleeved on the two ends of the motor shaft shaft shoulder; Described front end bearing gland right side contacts with front end bearing outer ring left side; Between described rear end bearing right side and rear end bearing gland left side, leave gap; Its improvements are: between rear end bearing right side and rear end bearing gland left side, be provided with lash adjusting device.
In said structure, described lash adjusting device comprises pressing plate, adjustment screw; Described adjustment screw is threaded in pressing plate, and its end is resisted against on pressing plate through pressing plate.
In said structure, described lash adjusting device also comprises fastening screw nut; Described fastening screw nut is threaded in adjustment screw, and is resisted against on rear end bearing gland.
The utility model compared with prior art, has following good effect:
1, pass through screw, pressing plate to bearing of motor end play, because screw adjustment end stretches out rear end bearing gland, therefore, can adjust at any time bearing of motor end play, convenient and swift, operate very simple.
2, in adjustment screw, fastening screw nut is set, is adjusting after bearing of motor end play, by fastening screw nut tight, play and prevent the loosening effect of adjustment screw, guaranteed the persistence of adjusting.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
