Abstract
The utility model discloses an automatic bearing in pump case of tolerance compensation, including bearing housing, main shaft, bearing, bearing cover, be equipped with the main shaft in the middle of the bearing housing, the bearing housing both ends are equipped with bearing cover, and the main shaft passes bearing housing and bearing cover's axis, and the bearing cover inboard is equipped with the bearing, and the bearing housing is equipped with mechanical spring between bearing cover and bearing on the main shaft, and the main shaft is connected to the mechanical spring lower extreme, and mechanical spring connects the upper end counterpoise spring lower extreme, and bearing box inner wall is connected to the counterpoise spring upper end. The utility model overcomes prior art's is not enough, and through setting up counterpoise spring and mechanical spring between bearing and end cover, mechanical spring slows down the bearing housing to the axial pressure of main shaft, and the counterpoise spring can compensate because the influence of processing tolerance, slows down the bearing housing to the pressure of bearing, convenient and practical, very big improvement the practical life of bearing and main shaft.
Description
Technical field
The utility model relates to bearing housing technical field, specifically belongs to a kind of bearing in pump case of automatic tolerance compensating.
Background technique
Bearing housing is made up of following accessory: bearing housing, bearing, pump shaft, bearing gland, oil sealing etc. form.Exist owing to there is inevitable tolerance in course of working, there is two states in bearing housing and the between centers size of original structure: size bearing bigger than normal cannot be stressed, and size shaft strength less than normal is excessive, causes bearing heating, affects bearing life.And, the axial pressure of bearing housing on main shaft excessive working life that also can affect main shaft.
Model utility content
The purpose of this utility model there is provided a kind of bearing in pump case of automatic tolerance compensating, overcome the deficiencies in the prior art, by arranging counterbalance spring and mechanical spring between bearing and end cap, mechanical spring slows down the axial pressure of bearing housing to main shaft, counterbalance spring can compensate the impact due to machining tolerance, slows down the pressure of bearing housing to bearing.
The technical solution adopted in the utility model is as follows:
A kind of bearing in pump case of automatic tolerance compensating, comprise bearing housing, main shaft, bearing, bearing gland, main shaft is provided with in the middle of described bearing housing, bearing housing two ends are provided with bearing gland, main shaft passes the axis of bearing housing and bearing gland, bearing is provided with inside bearing gland, bearing housing is on main shaft, mechanical spring is provided with between described bearing gland and bearing, mechanical spring lower end connects main shaft, mechanical spring upper end connects counterbalance spring lower end, counterbalance spring upper end connection bearing cabinet wall.
Described bearing gland and main shaft joint are provided with oil sealing.
Described oil sealing and bearing gland surface of contact are provided with tooth profile slice, and described bearing gland is provided with the circular groove corresponding with described tooth profile slice with oil sealing surface of contact, and described tooth profile slice and circular groove form labyrinth sealing.Labyrinth sealing shutoff is tight, stops oil leakage phenomenon.
Described bearing housing and bearing gland are bolted.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The utility model by arranging counterbalance spring and mechanical spring between bearing and end cap, mechanical spring slows down the axial pressure of bearing housing to main shaft, counterbalance spring can compensate the impact due to machining tolerance, slow down the pressure of bearing housing to bearing, convenient and practical, greatly improve the physical life of bearing and main shaft.
