Slidercrank mechanism comprises slide block, gearwheel, eccentric shaft.At body chute is set, slide block matches with chute, and is connected with plunger back-end.Chute is provided with cover plate.
Slide block can connect with plunger back-end by three kinds of modes:
1. make plunger pass the matching hole of follower plate, and by the bulge loop location of plunger termination, the screw hole that retaining screw is passed on the follower plate connects plunger and slide block are unsteady.
2. plunger is installed on the slide block base plate, slide block is fixed together by two straight pins and slide block base plate.Plunger, slide block, slide block base plate are formed to float and are connected.
3. plunger tail is provided with outside thread, and slide block is provided with internal thread, makes plunger and slide block adopt screw thread direct.
Reducing gear is a reduction gears mechanism.Reduction gears mechanism comprises motor, motor gear, planetary pinion, main shaft, driving gear, internal gear and gear box cover.Motor is by motor gear, successively with the gearwheel engagement all over axle of planetary pinion, band tooth main shaft and band.
Oil feeding mechanism is made of plunger in oil storage cylinder and the oil storage cylinder and spring.Oil feeding mechanism can adopt prior art.
Operating device comprises handle, cell bag and switch.Handle is fixed on the body.Cell bag and switch are loaded on the handle.
The utility model in use, motor is after gear reduction, motor speed reduces, the torsion of motor output has increased.Motor rotates through gear reduction rear driving gearwheel, is fixed in eccentric shaft on the gearwheel, drives slide block and does reciprocating linear motion in the body chute.The afterbody of plunger floats and is connected in the front end of slide block.It is together reciprocating that slide block drives plunger.When plunger moves backward, meeting negative pressure of generation of forced in airtight oil supply system, butter can reach under the thrust of oil-storing barrel spring, plunger under suction function, charges into the grease chamber of plunger pump.When plunger travels forward, be enclosed in the grease chamber butter and just forced to release through one-way valve by plunger.Move in circles the butter in draining grease bucket.
The utility model has the advantages that laborsavingly, fast, easy to operate, pressure is bigger, can satisfy common mechanical oiling requirement.
