Background technology
Bearing is that part that is fixed and reducing load coefficient of friction is played in mechanical transmission course.It may also be said that when other
When parts produce relative motion each other on axle, for reducing coefficient of friction and the holding shaft center in power transmission process
Fixed parts.Bearing is a kind of very important parts in contemporary plant equipment.Its major function is support machinery rotation
Swivel, to reduce mechanical load coefficient of friction of the equipment in transmission process.By the difference of motor element frictional property, bearing
Rolling bearing and the class of sliding bearing two can be divided into；In use, can be worn and torn unavoidably between bearing and axle, after long-time use,
The internal diameter of bearing and the diameter of axle are mismatched, it may occur that circular runout, and the parts on bearing made shift, and influence machinery is set
The stability of standby work, while also increasing the abrasion of axle, reduces the service life of axle, it is therefore necessary to change internal diameter less
Bearing, when being fixed by sleeve countershaft and bearing, existing technology is not sufficiently stable in the presence of fixation, is also easy to produce vibrations
Shortcoming.
The content of the invention
It is an object of the invention to provide a kind of tightening sleeve locking apparatus, with asking for solving to propose in above-mentioned background technology
Topic.
To achieve the above object, the present invention provides following technical scheme：A kind of tightening sleeve locking apparatus, including sleeve,
Rotating shaft and bearing, the rotating shaft are socketed in inside the sleeve, and the bearing is socketed the outside of the sleeve, the bearing
Axis direction of the inner ring along bearing be fixedly installed limited block, the limited block is strip, and the limited block is one end
Area of section be more than other end area of section ladder structure of right angle, the outer surface of the sleeve opens up limited location
Hole, the position of the spacing hole and the limited block is adapted, and the spacing hole is mutually to be fitted with the spacing block-shaped, size
The right-angled trapezium groove answered, the limited block is connected in the spacing hole, and described sleeve one end is provided with screwed pipe, the spiral shell
It is provided with fastening rotating disk on line pipe, the fastening rotating disk centrally through screw activity installs screwed pipe, and screwed pipe and fastening
Rotating disk is threadedly coupled.
It is preferred that, the limited block sets in the inwall of bearing and is evenly arranged with four groups.
It is preferred that, the diameter of bore of the sleeve and the diameter of the rotating shaft are adapted.
It is preferred that, the limited block is matched somebody with somebody with the spacing hole for gap.
It is preferred that, axis direction of the limited location hole along the sleeve is opened up, and the two ends of spacing hole are open
Structure.
Compared with prior art, the beneficial effects of the invention are as follows：
1st, axis direction of the present invention by the inner ring in bearing along bearing is fixedly installed limited block, and limited block is one end
Area of section be more than other end area of section ladder structure of right angle, while offered in the outer surface of sleeve with it is spacing
The adaptable spacing hole of block-shaped, size, and it is threaded with screwed pipe fastening rotating disk；During work, pass through rotational fastener
Rotating disk causes sleeve to be completely embedded with bearing, because the contact surface of limited block and spacing hole is inclined-plane, it is possible to improve tight
The stability being connected with bearing is covered calmly.
2nd, the present invention has the advantages that simple in construction, easy to use, using effect is good.
