Problems solved by technology

However, when the compressor starts to work, before the crankshaft speed is high enough, the moving parts of the movement are dry and there is no lubricating oil for lubrication, resulting in large starting friction resistance and difficult starting. Therefore, the motor in the compressor is required to have a large starting torque
At the same time, since there is no lubricating effect of lubricating oil when starting, it is easy to cause serious wear and tear, reducing the working life of the compressor

Embodiment Construction

[0012] The concept, specific structure and technical effects of the present invention will be clearly and completely described below in conjunction with the embodiments and accompanying drawings, so as to fully understand the purpose, features and effects of the present invention. The oil storage tank mentioned in this article does not only refer to the cylindrical oblique blind hole oil tank, but refers to the shape of the oil storage tank, the number of the oil storage tank or the arrangement position of the oil storage tank can be changed according to the specific implementation conditions to achieve a better performance. Oil storage effect and lubricating effect. The various technical features in the invention can be combined interactively on the premise of not conflicting with each other.

[0013] refer to figure 1 , figure 1 As a feasible embodiment of the present invention, a crankshaft structure of a refrigeration compressor designed with an oil storage tank is provi...

Abstract

The invention discloses a refrigeration compressor with oil storage grooves. The oil supply system is arranged on a crank shaft; grooves for storing lubricating oil are formed in a spiral oil groove in a main shaft part of the crank shaft and a spiral oil groove in the eccentric part of the crank shaft; then oil storage grooves are formed in the spiral oil grooves of the crank shaft. Through the adoption of the structure that the oil storage grooves are formed in spiral oil grooves in the main shaft part and in the eccentric part of the crank shaft, the lubricating oil in the spiral oil grooves can be collected when the compressor stops working, then when the compressor starts to work again, moving parts are lubricated quickly, the starting torque of the compressor can be reduced, the friction abrasion at the starting moment is reduced, and the operating life of the compressor is effectively prolonged. The compressor can be used for various occasions needing a piston type refrigeration compressor.

Description

technical field [0001] The invention relates to a refrigerating compressor, in particular to a refrigerating compressor for a vehicle-mounted refrigerator. Background technique [0002] The refrigeration compressor includes a closed casing 9 and core components in the casing, the bottom of the closed casing stores refrigerating machine oil for lubrication, and the crankshaft 13 tail in the core is soaked in the refrigerating machine oil. An inclined oil hole 141 is designed inside the tail section of the crankshaft 13, which is connected to the spiral oil groove 143 in the middle section through the communication hole 142 in the middle section, and connected to the spiral oil groove 16 in the crankshaft eccentric part 11 through the communication hole 144 in the upper section. When the refrigeration compressor starts to work, the crankshaft rotates at high speed, and the refrigerating machine oil at the bottom of the compressor shell is supplied to the spiral oil tank 143 in...
