Problems solved by technology

Due to the high viscosity and poor fluidity of the lubricating grease, the current grease injection equipment needs to take auxiliary measures to inject the grease in the grease bag, such as pressing the oil bag by hand, or using an auxiliary mechanical structure with a pressure plate and a spring, but the process is complicated , not easy to control, if the grease is used up, it is necessary to remove the oil bag repeatedly to replenish the grease, which is inconvenient to operate, and the repeated removal of the grease bag will easily cause the grease injection equipment to be polluted by dust, etc., resulting in a decline in the quality of the grease

Abstract

The invention discloses a grease injection device which comprises a device shell, two gears arranged in an inner cavity of the shell to form a gear pump structure and a grease bag fixed to the device shell and communicated with an oil suction cavity in the device shell. The grease bag comprises an upper connecting plate, a lower connecting plate and a tapered bag body fixed between the upper connecting plate and the lower connecting plate. The lower connecting plate is provided with an oil outlet for making an inner cavity of the tapered bag body communicated with the oil suction cavity of the device shell. According to the grease injection device, the grease bag and a pump body are combined into a whole, the grease flow path is short, the grease injection resistance is small, use is convenient, labor is saved, the grease in the tapered grease bag of the structure is fully sucked out conveniently, and the grease utilization rate can be increased.

Description

technical field [0001] The invention relates to the technical field of grease lubrication, in particular to a grease injection device. Background technique [0002] Usually, mechanical parts need to be injected with a certain amount of grease during assembly and maintenance. For example, bearings are mostly lubricated by grease, which can ensure the lubrication of parts, reduce relative friction and improve the reliability of parts. Due to the high viscosity and poor fluidity of the lubricating grease, the current grease injection equipment needs to take auxiliary measures to inject the grease in the grease bag, such as pressing the oil bag by hand, or using an auxiliary mechanical structure with a pressure plate and a spring, but the process is complicated , not easy to control, if the grease is used up, it is necessary to remove the oil bag repeatedly to replenish the grease, which is inconvenient to operate, and the repeated removal of the grease bag will easily cause the...
