Description

The sliding bearing press mounting tool

Technical field

The utility model belongs to mechanical processing technique equipment, particularly a kind of sliding bearing press mounting tool.

Background technology

At present, the gear pump of domestic and international application is more, in gear pump is used, friction and wear is the main cause that causes energy loss and consumption, is the principal element that affects service life and produce noise, and it is large that existing gear pump exists the friction surface roughness, contact area is little, contact point pressure is large, thereby causes service life low, and coefficient of friction is high, temperature rise, power attenuation is large, and efficient is low, the large deficiency that waits of noise; The one of the main reasons that above-mentioned phenomenon occurs be exactly the sliding bearing assembly quality bad due to, especially for the seat ring gear pump, press-fit frequent the appearance because bearing is pressed partially, strong skin in the process at sliding bearing and seat ring, cause that to press-fit rear sliding bearing endoporus cylindricity overproof, make oil clearance inequality between gear shaft and bearing, coefficient of friction is high, temperature rise, even excessively heated axle occurs or scratch phenomenon.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned technical deficiency, provides a kind of simple to operate, ensures the quality of products the sliding bearing press mounting tool that can enhance productivity.

The technical scheme that the utility model technical solution problem adopts is: the sliding bearing press mounting tool comprises base, pad, spring, seat ring, sliding bearing, hexagon socket cap head screw, the base that is characterized in the sliding bearing press mounting tool is provided with a groove one, the inner plane both sides of groove one are uniform respectively to be provided with a groove two, be laid with two top cover mounting holes in the middle of groove one inner plane, be provided with a groove three in the middle of the base end face, groove one interior activity on the base installs cover, on put and be respectively equipped with two sliding bearing installing holes two, two top thick stick mounting holes, a groove four, activity installs sliding bearing in the upper cover, the upper end of dress top, sliding bearing bottom face top thick stick, the top, lower end of top thick stick is contained in the upper end of screw top cover, thick stick upper end, top is installed in the top thick stick mounting hole of cover, the screw top cover hexagon socket cap head screw that is threaded, the screw top cover is installed in the top cover mounting hole, hexagon socket cap head screw is installed on the pad, pad places between the upper plane of groove three of hexagon socket cap head screw and base, a spring-loaded end is pressed respectively in both sides, upper cover bottom surface, the other end of spring is installed in the groove two of base, the groove four interior activities of upper cover install seat ring, and seat ring is provided with sliding bearing installing hole one.

The beneficial effects of the utility model are: the sliding bearing press mounting tool is simple to operate; convenient; save operation time greatly; enhance productivity; press-fiting precision is guaranteed by linearity and the perpendicularity of base inner wall; intuitively; can survey; improved and press-fited precision; reduced to greatest extent the distortion that press-fits of sliding bearing, can guarantee main; friction surface between driven gear shaft and sliding bearing has bed thickness from uniform composite membrane, has reduced the coefficient of sliding friction; reduce heat generation; temperature rise slows down, and reduces power attenuation, has improved gross efficiency; reduce noise, be conducive to the production environment protection.
