Abstract

The utility model relates to a mechanical transmission device for turning rotation into reciprocal movement, and belongs to the technical field of mechanical drive for turning rotation into reciprocal movement. An existing cam carrier mechanism is characterized in that the transference power is small, the oil seal is needed, a roller and a cam line are contacted, parts are easy to wear, etc. The utility model has the technical proposal that a push rod which is supported by a machine frame and is provided with a spring is provided with a gear which can rotate freely; the gear is meshed with an eccentric gear which is driven by a motor. The structure has the characteristics of simple and compact structure, large transference power, no need of oil seal, no sliding friction among transmission parts, wear resistant parts, easy manufacturing, high efficiency, etc. The device can be used for reciprocating saws, electric hammers, concrete vibrators, vibrating sieves, vibrating road rollers, electric cutters of apparel industry, etc.

Description

Become reciprocating mechanical transmission by rotating
The utility model relates to by rotating the reciprocating mechanical transmission fields of change.
At present, there have cam follower mechanism to exist transferring power by rotation change to-and-fro motion to be little, needs oil sealing, and roller is that line contacts with cam, the shortcoming that part is easy to wear.Though the linkage mechanism transferring power is big, because moving element is many, many parts are done variable motion, because the effect of inertial force, mechanical efficiency is low.
It is a kind of simple and compact for structure that the utility model provides, and component processing is manufactured easily; Transferring power is big, does not need oil sealing, the fricton-tight friction of transmission part, mechanical efficiency height, the nonabradable mechanical transmission of transmission part.
The utility model is achieved in that on the push rod by frame support, and gear free to rotate is housed, and spring is equipped with in this gear and the engagement of motor-operated eccentricity gear on the push rod.
The utility model concrete structure is provided by following examples and accompanying drawing.
Figure of description is the utility model, by rotating the schematic representation that becomes the to-and-fro motion mechanical transmission.
Describe specific structural details of the present utility model and working condition in detail below in conjunction with accompanying drawing:
(1) is push rod; (2) be spring; (3) be frame; (4) be gear; (5) be eccentricity gear; (6) be casing, frame (3) and eccentricity gear (5) are installed in the casing (6).Push rod (1) is gone up gear (4) and eccentricity gear (5) engagement that connects.When eccentricity gear (5) is turned to by minor radius in the long radius process, push rod (1) the externally acting of sliding.Spring (2) is compressed storage elasticity potential energy, when eccentricity gear (5) by long radius in the minor radius rotation process, spring (2) discharges elastic potential energy, to push rod 1 and eccentricity gear (5) acting.Make push rod (1) get back to initial position.
The utility model can be used for producing reciprocating saw, electric pick, concrete vibrating handful, vibrating sieve, vibratory roller, clothing industry electric cutting knife etc.

Claims (4)

1, a kind of by rotating the reciprocating mechanical transmission of change, its structure is the push rod that moves reciprocatingly (1) of frame (3) support and the eccentricity gear (5) of driven by motor, it is characterized in that push rod (1) is equipped with gear free to rotate (4).
2, become reciprocating mechanical transmission according to claim (1) is described by rotating, it is characterized in that push rod (1) is equipped with spring (2).
3, become reciprocating mechanical transmission according to claim (1) is described by rotating, it is characterized in that eccentricity gear is arranged (5).
