Automatic grease-injection device of bearing

Abstract

The invention discloses an automatic grease-injection device of a bearing. The automatic grease- injection device of the bearing comprises a driving belt, grease discharging thin pipes, a grease storing box, a T-shaped supporting frame and an air pressure adjusting valve. Bearing grooves are fixedly arranged on the driving belt, the T-shaped supporting frame is arranged on one side of the driving belt, and an upper piston bucket is arranged on one side of the bottom of a cross beam of the T-shaped supporting frame. The upper piston bucket is connected with a lower piston bucket through an inner double-end piston rod, a pneumatic pump is connected with the lower portion of an electromagnetic valve, and the air pressure adjusting valve is arranged in the middle position between the electromagnetic valve and the pneumatic pump. According to the automatic grease-injection device of the bearing, the bearing is subjected to grease injection by combination of automatic transmission and quantitative grease injection. The driving belt can enable the grease injection of the bearing to be streamlined, grease-injection efficiency is improved, and manual cost is reduced. The grease discharging thin pipes distributed in a ring shape, an infrared detector and the air pressure adjusting valve can enable fat to be injected between the inner ring and the outer ring of the bearing evenly, accurately and quantitatively, so that a reject ratio of the grease injection is reduced.

Problems solved by technology

[0002] With the development of the times, people's living standards continue to improve, and industrialization and intelligence are also constantly innovating and developing. Bearings are commonly used transmission components in the field of industrial equipment and are widely used in various equipment. Bearings are a precision Mechanical basic parts, according to the requirements of the product, the bearing must be filled with a certain amount of grease before leaving the factory. During the grease injection process of the bearing, the grease needs to be injected into the ball between the inner and outer rings of the bearing. The existing grease injector There are many problems in the grease injection process. Too little grease injection will easily cause lack of grease or dry friction, which will affect the service life of the bearing; too much grease injection will cause the temperature of the bearing to rise, resulting in grease leakage, which pollutes the environment. , and cause waste. Usually, the oil pump is used to extract grease into the bearing. Air may be mixed in during the extraction process to form air bubbles, thereby affecting the lubrication effect of the grease. Therefore, it is necessary to improve the existing grease injection device to solve the above problems. The problem
