Vortex compression device with antifriction buffer cross-shaped slip ring

Abstract

The invention discloses a scroll compression device with an anti-friction buffer cross-shaped slip ring, which is used for preventing rotation and reducing friction of a scroll compressor. The cross-shaped sliding ring comprises a cross-shaped sliding ring body, a bearing, stepped-shaft-shaped sliding keys, oil passing grooves, a movable scroll plate and a rack, the movable scroll plate and the rack are matched with each other, the stepped-shaft-shaped sliding keys are sleeved with the bearing, and the sliding keys are distributed on the upper end face and the lower end face of the cross-shaped sliding ring in a cross-shaped symmetry mode. During working, the upper end face and the lower end face are attached to the movable scroll plate and the machine frame in a sliding mode respectively, the cross-shaped symmetrical sliding keys on the upper end face and the lower end face do reciprocating rolling motion in the guide sliding grooves in the movable scroll plate and the machine frame, and the lower portion of the stepped shaft sliding key does not make contact with the guide sliding grooves in the movable scroll plate and the machine frame. Generally, rolling friction is 1 / 40 of sliding friction, and according to the principle, the bearing sliding keys are adopted, so that the contact area and friction loss between the bearing sliding keys and the rack and between the bearing sliding keys and the guide sliding grooves of the movable scroll plate are reduced. The antifriction cross slip ring is easy to machine, low in cost and more stable and efficient in work.

Description

technical field [0001] The invention relates to the technical field of scroll compressor accessories, in particular to a scroll compression device with a friction-reducing buffer cross slip ring. Background technique [0002] The scroll compressor mentioned in the present invention is widely used in occasions requiring refrigeration, air conditioning and aerodynamics, such as industry, agriculture, transportation, medical equipment, food decoration, textiles and the like. [0003] Usually, in order to ensure that the scroll compressor performs revolution and translation around the fixed scroll with a fixed radius of rotation to form an effective volume cavity, it is necessary to design a set of anti-rotation mechanism. Oldham slip rings are widely used in anti-rotation of scroll compressors because of their simple process and easy assembly. The wear and impact of the Oldham slip ring have a significant impact on the precise meshing of the movable scroll and the fixed scroll...
