A lithium base grease automatic filling device

Abstract

The invention discloses an auto-lubrication device for lithium-based grease and lubricating grease. The auto-lubrication device for the lithium-based grease and the lubricating grease comprises a support. An oil cylinder is fixedly connected on the support, the bottom end of the oil cylinder is provided with an oil extraction pipe which extends out of the bottom end of the support and is fixedly connected with an oil pump, and an oil outlet pipe is arranged on the oil pump. A round piston is arranged in the oil cylinder, and the middle of the top end of the piston is provided with a screw rod. The middle of the top end of the oil cylinder is fixedly connected with a shaft sleeve, and the upper end of the screw rod inserts into the shaft sleeve. The top end of the shaft sleeve is provided with an auxiliary conical gear which can freely rotate, and a screw hole which is matched with the external threads of the screw rod is formed in the middle of the auxiliary conical gear. The edge of the top end of the oily cylinder is further provided with a motor through a motor base, the output end of the motor is provided with a rotary shaft, and the tail end of the rotary shaft is fixedly connected with a main conical gear which is meshed with the auxiliary conical gear. The auto-lubrication device for the lithium-based grease and the lubricating grease has the advantages that the pressure is constant, the problems of little oil amount and poor lubricating effect due to over-low pressure cannot occur, the situation that the oil cylinder cannot be filled up due to over-high pressure also cannot occur, frequent filling for many times can be avoided, and the manpower and the time can be effectively saved.

Description

technical field [0001] The invention relates to the technical field of vehicle centralized lubrication, in particular to a lithium-based grease automatic grease filling device. Background technique [0002] With the rapid development of the automobile industry, the energy loss and wear caused by the friction pairs of automobile moving parts cannot be ignored. The lubrication system plays a vital role. In the relevant regulations of our country, the centralized lubrication system of automobile chassis has become a high It is a necessary device for large and medium-sized passenger cars above the grade. The main part of the centralized lubrication system is grease, which is a structural dispersion system formed by base oil, thickener and various additives, and is a typical non-Newtonian fluid. Due to the complexity of the medium flow, the structural design of the centralized lubrication system has been mainly dependent on the experience and skills of engineers and technicians ...
