Electric grease injecting machine

Abstract

The invention discloses an electric grease injecting machine comprising a grease pumping device. The upper end of the grease pumping device is coaxially connected with a fixed seat which is vertically connected with a drive motor; a reversing mechanism is arranged in the fixed seat and comprises a bearing block, a pair of ball bearings and an eccentric wheel in sequence from the outside to the inside; the eccentric wheel is provided with a key slot; a motor driving shaft is provided with a key which is in interference fit with the key slot, is connected with the eccentric wheel by a key, and drives the eccentric wheel to do 360-degree rotating motion; the eccentric wheel is connected with the bearing block through a pair of ball bearings and drives the bearing block to do up-down reciprocating motion; the bearing block is movably connected with a driving rod through a driving rod joint; the fixed seat is connected with a pump body through an inner connecting pipe; and the fixed seat is provided with a pressure adjusting mechanism communicated with a pump body oil path. The invention carries out grease injecting operation under the condition of having no air source by only taking a common single-phase 220V power supply as the power; in addition, the invention has the advantages of widening the application range, prolonging the service life of the reversing mechanism, and reducing the wear degree of oil seal.

Description

technical field [0001] The invention belongs to the technical field of high-pressure grease injection equipment, and relates to oil injection equipment powered by a single-phase 220V power supply, in particular to an electric grease injection machine. Background technique [0002] For the moving parts in mechanical equipment, especially the moving parts rotating at high speed, regular grease lubrication is required to reduce the mutual friction between the parts and prolong the service life of the parts. [0003] In the prior art, a pneumatic high-pressure lubricator is widely used as a device for adding lubricating grease to mechanical equipment. [0004] Although the pneumatic high-pressure lubricator has the characteristics of high working efficiency, due to the complex structure of its reversing mechanism, it is easy to fail, which shortens the service life of the air pump unit of the whole machine and has a high failure rate. In particular, it is necessary to convert i...

Problems solved by technology

[0004] Although the pneumatic high-pressure oiler has the characteristics of high working efficiency, due to the complex structure of its reversing mechanism, it is easy to fail, which shortens the service life of the air pump unit of the whole machine, and its failure rate is high

In particular, it is necessary to convert its power supply into a compressed air source to carry out the oil injection operation, so the air compressor needs to be started frequently and the compressed air is lost

And when working, the noise of the air compressor exhaust is very loud, which seriously affects the working environment of the operators
