Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] refer to figure 1 , figure 2 , a low-friction reciprocating structure that is easy to replace, a supporting ring 3 is installed on the outer edge of the end face of the piston 6, and the outer side of the supporting ring 3 is supported by one end of the baffle 2, and the other end of the baffle 2 is detachable by a screw 1 It is installed on the piston 6; and there is a gap between the baffle plate 2 and the piston 6, and the gap can realize the application of the pre-tightening force on the support ring. Adjust the pre-tightening force through the screw 1, so that the baffle plate 2 evenly presses the support ring 3 to ensure that the support ring 3 does not shake in the groove of the piston 6 or bend and protrude due to excessive force when the piston 6 reciprocates.

[0019] There is a height difference between the support ring 3...

Abstract

The invention discloses a low-friction reciprocating motion structure easy to replace. The low-friction reciprocating motion structure easy to replace is characterized in that a support ring is mounted at the outer edge of the end face of a piston, the outer side of the support ring is propped against one end of a baffle, the other end of the baffle is detachably mounted on the piston, a gap is reserved between the baffle and the piston, and a height difference is reserved between the upper end face of the supporting ring and the upper end face of the piston. According to the low-friction reciprocating motion structure easy to replace, the supporting ring is detachably mounted on the piston through screws, the problems that a friction pad of a reciprocating motion piston is larger in friction force and difficult to detach are solved, and meanwhile for frequent reciprocating motion of the piston, the sealing problem of the piston is solved, installation is convenient and easy, part machining procedures are reduced, friction force between relative motions is reduced, and production cost is effectively reduced.

Description

technical field [0001] As a field of general mechanical equipment, the invention specifically relates to an easy-to-replace low-friction reciprocating structure. Background technique [0002] The supporting structure of the piston in the reciprocating motion structure is a very critical part. If the structural design is unreasonable, it will affect the overall performance of the valve movement, especially the structural design of the piston supporting ring requires low friction and easy replacement. [0003] Usually, the reciprocating piston has a friction pad, which is directly embedded in the groove of the piston. Frequent movement and extrusion will cause the friction pad to deform. The personnel caused great difficulties; the piston is generally sealed with an O-ring. However, due to the frequent reciprocating movement of the piston and the high impact force, the O-ring is squeezed and cut by the edge of the groove, thus losing its sealing effect. Therefore, it is still...
