Reciprocating motion structure of non-eccentric mechanism

Abstract

The reciprocating motion structure of the non-eccentric mechanism comprises a gear box lower cover, a triangular cam and a reciprocating rod, the gear box lower cover and a gear box upper cover are installed in a covering mode through screws, a motor is installed on one side of the gear box lower cover through screws, a first gear is installed in the center of a third positioning pin, and a second gear is installed in the center of a third positioning pin. The first gear is in transmission connection with the second gear, the reciprocating rod is installed on the outer side of a triangular cam on the upper surface of the first gear, and the second gear is a driving gear and is driven by a motor to input power. According to the reciprocating motion structure of the non-eccentric mechanism, a traditional eccentric reciprocating mechanism is broken through, reciprocating motion is achieved through the non-eccentric structure, and vibration generated by rotation of the first gear is eliminated; and a balancing weight is arranged, so that the vibration generated in the reciprocating process of continuously accelerating and decelerating the saw blade is solved, the vibration acting force is self-counteracted, the vibration of the whole machine is reduced, the comfort of the whole machine is realized, and the service life of the product is prolonged.

Description

technical field [0001] The invention relates to the technical field of electric tools, in particular to a reciprocating motion structure of a non-eccentric mechanism. Background technique [0002] Electric reciprocating saw is a power tool for sawing with a reciprocating saw blade, one of the commonly used tools in construction sites and home improvement. Vibration (also known as oscillation) is defined as a process of state change, that is, the reciprocating motion of an object. The reciprocating saw uses this reciprocating motion, but its defects are also obvious, that is, the vibration is large. A pair of bevel gears are often eccentrically driven in the reciprocating sawtooth gear box to drive the output shaft to reciprocate. However, during the reciprocating process, due to the eccentricity of the first gear, the imbalance of the counterweight, and the continuous acceleration and deceleration of the saw blade, this inevitably leads to a large vibration of the reciproca...

Problems solved by technology

However, during the reciprocating process, due to the eccentricity of the first gear, the imbalance of the counterweight, and the continuous acceleration and deceleration of the saw blade, this inevitably leads to a large vibration of the reciprocating saw, which not only increases the noise, but also makes the operator uncomfortable
