Embodiment Construction

[0028] see in conjunction Figure 1 to Figure 6 As shown, according to an embodiment of the present application, a pump body assembly includes:

[0029] The crankshaft 1 includes an eccentric portion 11;

[0030] The roller 2 is sleeved on the eccentric part 11, and the inner wall of the roller 2 is in contact with the outer wall of the eccentric part 11;

[0031] The inner wall of the roller 2 and / or the outer wall of the eccentric part 11 is provided with a limiting assembly 3 for limiting the relative movement of the roller 2 and the crankshaft 1 in the axial direction.

[0032] The aforementioned relative movement in the axial direction includes axial movement along the axis, and axial swing of the axis to both sides.

[0033] In this application, a limiter is set on the corresponding mating surface between the crankshaft 1 and the roller 2 to limit the relative movement in the axial direction, so as to improve the shaking phenomenon of the crankshaft 1 during the actual...

Abstract

The invention provides a pump body assembly and a compressor. The pump body assembly comprises a crankshaft which comprises an eccentric part; and a roller arranged on the eccentric part in a sleeving manner, wherein the inner wall of the roller is in contact with the outer wall of the eccentric part; a limiting assembly is arranged on the inner wall of the roller and / or the outer wall of the eccentric part and used for limiting relative movement of the roller and the crankshaft in the axial direction. A limiting piece for limiting relative movement in the axial direction is arranged on the corresponding matching face between the crankshaft and the roller, so that the shaking phenomenon in the actual rotation process of the crankshaft is improved, contact abrasion between the crankshaft and other parts such as the upper flange, the lower flange and the roller is reduced, moreover, the contact stress between the lower thrust face of the crankshaft and the end face of the lower flange is reduced, and the abrasion degree of the lower thrust surface of the crankshaft and the lower flange contact surface is reduced.

Description

technical field [0001] The application belongs to the technical field of compressors, and in particular relates to a pump body assembly and a compressor. Background technique [0002] The rolling roller compressor is mainly composed of the pump body and the motor; among them, the pump body assembly mainly includes the cylinder, crankshaft, roller, sliding vane and upper and lower flanges. The line contacts against the outer surface of the roller, so that the inner volume composed of the cylinder and the roller is divided into two crescent-shaped suction chambers and compression chambers. Its working principle is that the crankshaft rotates periodically under the driving force of the motor, and drives the rollers to rotate synchronously and eccentrically through its eccentric structure, and then the sliding vane can perform radial reciprocating motion in the sliding vane groove of the cylinder, so that the suction The volume of the chamber and the compression chamber changes...
