Detailed Description

The utility model will be further described with reference to the accompanying drawings in which: as shown in the figure, the oil supply mechanism of the overedger comprises a transmission shaft 1 arranged in a shell 9 and further comprises a pump sleeve 2, wherein an eccentric part 11 is arranged on the transmission shaft, the eccentric part is arranged in the pump sleeve, the pump sleeve is radially provided with an oil inlet 21, an oil outlet 22 and a plunger hole 23, an elastic part 231 and a plunger 232 are arranged in the plunger hole, and the plunger is contacted with the outer wall of the transmission shaft under the action of the elastic part; the transmission shaft includes its eccentric portion with the relative oil inlet position that sets up of oil outlet with the eccentric portion with the relative oil outlet position that sets up of oil inlet. One of the most optional schemes is that the eccentric part is a bulge on the transmission shaft, on the other hand, the part of the cross section of the transmission shaft, which is opposite to the pump sleeve, can be set to be oval, when oil is absorbed, referring to fig. 2, the eccentric part is arranged opposite to the oil outlet, and the end with the smaller diameter faces the oil inlet, at this time, the oil enters the empty groove 101, and then the transmission shaft rotates clockwise, so that the oil is extruded from the oil outlet, on the other hand, the plunger is always contacted with the outer wall of the transmission shaft under the action of the elastic piece, the elastic piece can be a spring, an elastic sheet and the like, when the elastic sheet is used, the two ends of the elastic sheet are respectively contacted with the plunger and the supporting surface, and the contact surface can be the inner wall of the pump sleeve.

In the present invention, as shown in the drawings, the elastic member is a spring. The spring is adopted, so that the plunger is easy to disassemble and assemble, the plunger can be provided with the containing groove as the preference, then one end of the spring extends into the containing groove to be contacted with the bottom of the containing groove, and the other end of the spring is abutted against the pump sleeve.

In the present invention, as shown in the figure, the pump set includes a first pump set 201 and a second pump set 202 which are detachably connected. The pump sleeve is a split type first pump sleeve and a split type second pump sleeve, can be detached, is convenient to assemble and replace, and can be fixed by screws or pins and the like.

In the present invention, as shown in the drawings, the first pump set and the second pump set are coupled by a screw 203. Through the screw connection, also can pass through the bolt and pass modes such as back by nut fixed, the dismouting is fairly simple.
