Abstract
The utility model discloses a rotary -type ball of nut is vice with locking device, vice including ball, ball nut, as to contain antifriction bearing casing and nut cover, the ball nut is vice to be connected on ball and with the casing with nut cover suit, is equipped with lock nut in the nut cover outside, and the end connection of this lock nut's one end and casing, is equipped with locking gasket and circlip at lock nut's the other end. The utility model discloses furthest has reduced the not hard up possibility of the rotary -type vice locking device of ball of traditional nut, has improved the vice reliability of the rotary -type ball of nut greatly.
Description
Technical field
The utility model relates to a kind of ball screw pair, specifically a kind of nut rotating type ball screw pair with locking device.The utility model reduces the possibility that conventional nut rotating type ball screw pair locking device loosens to greatest extent, substantially increases the reliability of nut rotating type ball screw pair.
Background technique
At present, the locking effect of nut rotating type ball screw pair locking device mainly sees that the end-face friction of locking nut self ensures.But in actual using process, due to foozle and assembly error, cause actual coupling mechanism force may be far smaller than theoretical coupling mechanism force, thus cause locking device to loosen even coming off, so former designed reliability is not high.
Summary of the invention
In order to overcome prior art Problems existing, the purpose of this utility model is to provide a kind of nut rotating type ball screw pair with locking device, this ball screw pair reduces the possibility that locking device loosens to greatest extent, substantially increases the reliability of nut rotating type ball screw pair.
The purpose of this utility model is achieved through the following technical solutions:
A kind of nut rotating type ball screw pair with locking device, comprise ball screw, ball nut secondary, containing the housing of rolling bearing and nut sleeve, secondary and the nut sleeve of ball nut to be sleeved on ball screw and to be connected with housing, it is characterized in that: outside nut sleeve, be provided with locking nut, and one end of this locking nut is connected with the end of housing, be provided with locked spacer and circlip at the other end of locking nut.
In the utility model, locking nut, locked spacer and circlip are all sleeved in nut sleeve.Circlip is arranged on outside locked spacer.
The utility model uses the locking device be made up of locked spacer, circlip, loosens by shearing force opposing locking nut.After using a period of time, if rolling bearing produces gap because of wearing and tearing, also again can regain pretightening force by match grinding locked spacer.
Compared with prior art, the utility model reduces the possibility that locking device loosens to greatest extent, substantially increases the reliability of nut rotating type ball screw pair.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1 is ball screw, and 2 is that ball nut is secondary, and 3 is housing (containing rolling bearing), and 4 is locking nut, and 5 is locked spacer, and 6 is circlip, and 7 is nut sleeve.
Embodiment
There is a nut rotating type ball screw pair for locking device, comprise ball screw 1, ball nut pair 2, containing the housing 3 of rolling bearing and nut sleeve 7, the secondary and nut sleeve of ball nut to be sleeved on ball screw and to be connected with housing.Outside nut sleeve, be provided with locking nut 4, and the inner opposite end of this locking nut is connected with the end of housing, is provided with locked spacer 5 and circlip 6 at the other end of locking nut.Locking nut, locked spacer and circlip are all sleeved in nut sleeve.Circlip is arranged on outside locked spacer.
During work, ball screw original place maintains static.Power source drives ball nut secondary while rotate, an edge raceway straight line motion.Nut sleeve is arranged in ball nut pair, is considered as one, its outer holder housing (containing rolling bearing) with ball nut pair.Housing does straight line motion by ball nut subband is dynamic along raceway.Locking nut compresses bearing and provides pretightening force, and its outer installation locked spacer and circlip, ensure that locking nut does not loosen.Substantially increase the reliability of nut rotating type ball screw pair.
