Abstract
The invention discloses a nut rotation type ball screw pair with an anti-loosening device. The nut rotation type ball screw pair comprises a ball screw, a ball nut pair, a shell containing a rolling bearing, and a nut sleeve. The ball nut pair and the sleeve nut are arranged on the ball screw in a sleeving manner and connected with the shell. A locking nut is arranged on the outer side of the nut sleeve. One end of the locking nut is connected with the end of the shell. The other end of the locking nut is provided with a stop gasket and an elastic check ring. The possibility that a traditional nut rotation type ball lead screw pair locking device gets loose is reduced to the maximum extent, and the reliability of the nut rotation type ball screw pair is greatly improved.
Description
Technical field
The present invention relates to a kind of ball screw pair, specifically a kind of nut rotating type ball screw pair with locking device.The present invention 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 object of this invention 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 object of the invention is to be 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 present invention, locking nut, locked spacer and circlip are all sleeved in nut sleeve.Circlip is arranged on outside locked spacer.
The present invention 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 present invention 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 invention.
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.
