Plunger type grease injection device

Abstract

The invention provides a plunger type grease injection device which comprises a driving mechanism, a grease supply mechanism, a plunger pump, a supporting structure and a housing. The housing comprises an upper housing and a lower housing. The driving mechanism comprises a direct-current motor, a large-speed-ratio gear train, a slider-crank mechanism, a worm wheel and a worm. The slider-crank mechanism comprises a crank and a slider. The supporting structure comprises a rotary connector and a connecting plate. The rotary connector is fixed to the large-speed-ratio gear train. One end of the rotary connector is connected with the grease supply mechanism, and the other end of the rotary connector is connected with the plunger pump. The large-speed-ratio gear train is connected with the wormthrough an output shaft. The plunger pump is connected with the worm wheel through the crank. The connecting plate is connected with the grease supply mechanism. According to the plunger type grease injection device, a great cup is more convenient to replace, grease output pressure is larger, the motor power consumption is lower, the overall structure is compact, and the plunger type grease injection device can adapt to large mechanical device grease lubrication occasions.

Description

technical field [0001] The invention relates to the field of a grease injection device, in particular to a plunger type grease injection device. Background technique [0002] Grease plays a very important role in bearings. Grease has good adhesion, wear resistance, temperature resistance, rust resistance and lubricity. It can improve high temperature oxidation resistance, delay aging, and dissolve carbon deposits. Prevent the accumulation of metal wear debris and oil stains, and improve the wear resistance, pressure resistance and corrosion resistance of machinery. Common bearings include outer rings, inner rings, rolling elements and cages. The ratio of grease injection volume and grease supply volume of existing grease injection equipment cannot be adjusted, and different pipeline pressures directly affect the grease flow output by the pump. In reality, there are often situations where the pump capacity is not properly matched. Waste and pollute the environment; Another ...
