Description

Automatic oiling gearbox body

Technical Field

The utility model belongs to the technical field of speed changing devices, relates to a gearbox, and particularly relates to an automatic oil injection gearbox body.

Background

What the essence of gearbox is popular actually says is a gear box, reach the purpose that changes gear ratio and torque through set up installation gear train and gear shaft in the box, the gearbox is also called the reducing gear box, the gearbox need fill lubricating oil in inside when using, and fluid can the gradual loss in operation process, damage the gearbox in order to prevent that fluid reduces, generally need regularly to annotate machine oil or directly change machine oil in the gearbox, among the prior art, in order to prevent that the inside fluid of gearbox reduces, install the oil cup on the box, and all be the through type between conventional oil cup and the box, make the fluid in the box be in and fill the state, therefore the resistance of gearbox operation increases and fluid leaks easily.

Disclosure of Invention

The utility model aims to solve the problems in the prior art and provide a gearbox body capable of automatically injecting oil to keep oil in the gearbox body at a certain height.

The purpose of the utility model can be realized by the following technical scheme: the utility model provides an automatic oiling gearbox body, includes box and base, the box on coaxial input shaft and the output shaft of being provided with, input shaft and output shaft between realize slowing down through planetary gear set, its characterized in that, the top seal of box installs the oil cup, the oil cup on have an oil-out, the oil-out stretch into in the box, the oil-out on radially set up a plurality of and the inside runner that communicates of box, the junction of runner is provided with the floater, the diameter of floater is greater than the diameter of oil-out, the vertical connecting rod that is fixed with in bottom of floater, the other end of connecting rod is fixed with the kickboard.

The principle of the automatic oil injection gearbox body is that engine oil is filled in the gearbox body, the liquid level of the engine oil is at a certain height, so that a space is reserved between the liquid level of the engine oil and the top of the gearbox body, and running resistance of the gearbox is favorably reduced.

In the automatic oiling gearbox body, a cover plate is arranged at the joint between the oil cup and the gearbox body, the oil cup is fixed on the cover plate, and the cover plate is fixed on the gearbox body.

In the automatic oiling gearbox body, external threads are arranged outside the oil outlet, and the oil cup and the cover plate are fixed in a matched mode through threads.

In the automatic oiling gearbox body, a circle of annular teeth are arranged on the outer wall of the oil cup.

In the automatic oiling gearbox body, the bottom of the gearbox body is provided with an oil drain plug screw.

Compared with the prior art, this automatic oiling gearbox casing sets up floater and kickboard through the oil-out at the oil cup, thereby drives the floater through the kickboard and reciprocates the height of control box liquid level in the oil outlet, thereby has the problem that effectively prevents the gearbox and move the damage under the state of lacking oil, thereby makes simultaneously fluid keep in the optimum position in the box, the higher advantage of gearbox operating efficiency.
