Automatic lubricating device

Abstract

The invention discloses an automatic lubricating device. The automatic lubricating device comprises a lubricating mechanism and an oil replenishing mechanism. During lubricating operation, operating personnel unlocks an oil driving piston, and lubricating operation can be automatically finished under the action of a driving spring; after the completion of lubrication, an oil replenishing cylinder is communicated with a lubricating cylinder, the oil replenishing mechanism can be used for automatically finished oil replenishment, and the oil driving piston, a connecting rod and the driving spring are driven to restore to initial positions. During lubrication and oil replenishment, the automatic lubricating device is very easy to operate; moreover, during each oil replenishment and lubrication, the motion travel of the oil driving piston is the same, so that the volume amount of lubricating oil output each time can be kept the same, and a uniform lubricating effect is ensured. Moreover, the lubricating cylinder in the lubricating device is conical, and only one oil flow port positioned in a cone bottom is formed, so that the oil driving piston can be protected from being scratched by the oil flow port in a reciprocating motion process.

Description

technical field [0001] The invention relates to the lubricating technology of mechanical products, in particular to an automatic lubricating device. Background technique [0002] Wear is an important cause of product scrapping or performance degradation; in order to prevent the adverse effects of dry friction, mechanical products attach great importance to the lubrication between kinematic pairs. According to different degrees of intelligence, lubrication methods can be divided into two types: automatic lubrication and manual lubrication. Among them, automatic lubrication specifically refers to the process of transporting lubricating oil / grease to a predetermined lubrication point through a lubricating oil pump / lubricating grease pump through a lubricating channel. This lubrication method can realize automatic lubrication during the working process of mechanical products without manual operation, and has a high degree of intelligence; manual lubrication injects grease or oil...

According to different degrees of intelligence, lubrication methods can be divided into two types: automatic lubrication and manual lubrication. Among them, automatic lubrication specifically refers to the process of transporting lubricating oil / grease to a predetermined lubrication point through a lubricating oil pump / lubricating grease pump through a lubricating channel. This lubrication method can realize automatic lubrication during the working process of mechanical products without manual operation, and has a high degree of intelligence; manual lubrication injects grease or lubricating oil into predetermined lubrication points manually, and then gives zero Lubricate the components; on the operating machinery with a low degree of automation, the manual lubrication method is usually used. This lubrication method relies on the manual operation of the operator, and the amount of lubricating oil or grease injected each time is different, so the lubrication effect of each time not exactly the same
