Abstract

The invention discloses an efficient bearing grease injecting device. The efficient bearing grease injecting device comprises a working table, a lubricating grease barrel, a grease injecting gun, a cylinder, an electromagnetic valve, a pressure gauge and an air supply device; a bearing grease injecting tank is formed in the working table; multiple fixing frames are mounted on the working table; a control box is fixed on the working table; a control device and a power supply are arranged in the control box, and are connected by a lead; the lubricating grease barrel is mounted on the fixing frames; a temperature adjusting device is arranged at the bottom of the lubricating grease barrel; a grease outlet is formed in the lower end of the lubricating grease barrel; a grease inlet is formed in the grease injecting gun; the grease injecting gun and the lubricating grease barrel are connected by a grease conveying pipe; the cylinder is rightly above the grease injecting gun; a double-end piston is arranged in the cylinder; the two ends of the double-end piston are respectively connected with the cylinder and the grease injecting gun; the cylinder is connected with the electromagnetic valve; the two ends of the electromagnetic valve are connected with a time relay in parallel; the electromagnetic valve and the air supply device at the lower side are connected by an air conveying pipe; and the pressure gauge is connected with the air conveying pipe.

Description

【Technical field】 [0001] The invention relates to the technical field of bearing production equipment, in particular to the technical field of a high-efficiency bearing grease injection device. 【Background technique】 [0002] Bearings are commonly used transmission parts in the field of industrial equipment and are widely used in various equipment. Bearings are a kind of precision mechanical basic parts. According to the requirements of the product, the bearings must be filled with a certain amount of lithium-based grease before leaving the factory. During the grease injection process, grease needs to be injected between the inner and outer rings of the bearing. For the use of open bearings, a sealing device is also set in the main engine to prevent the leakage of grease. This raises the question of how much grease to inject into the bearing. Too little grease injection will easily lead to lack of grease or dry friction, which will affect the service life; too much grease ...

AI Technical Summary

Problems solved by technology

Because air may be mixed in the material barrel to form air bubbles, the grease injected between the inner and outer rings of the bearing through the oil pump will contain air bubbles, which will affect the lubricating effect of the grease

There are also grease injection methods that rely on manual smearing or manual extrusion. Not only is the labor intensity of workers high, but also the amount of grease injection is difficult to guarantee, thus affecting the performance of the bearing. Difficult to popularize, different shapes of lubricating grease at different temperatures will affect the lubrication effect of bearings
