Abstract
Provided is a transmission mechanism for a reciprocating saw, wherein the transmission mechanism comprises a transmission assembly and a housing assembly sleeved outside the transmission assembly. The transmission assembly comprises a transmission cam and a reciprocating output shaft. The transmission cam comprises a cam body, the bottom of which is equipped with a transmission part in transmission connection with a motor of the reciprocating saw. An oblique guide groove is provided around the periphery of the surface of the cam body. The reciprocating output shaft comprises an output shaft body, the bottom of which are symmetrically provided with two transmission arms. The cam body of the transmission cam is clamped between the two transmission arms, each of which is respectively provided with a circular groove. The circular groove and the oblique guide groove are intersected to form a sliding track, in which two steel balls are symmetrically arranged. The transmission cam is driven to rotate by the motor, and meanwhile the steel balls slide along the guide groove, so as to drive the reciprocating output shaft to make reciprocating movements. Therefore, normal transmission can be performed without too much lubricating oils required for dot surface contact between the transmission parts, and the movement damage of the transmission mechanism of the invention is much less than that of conventional mechanisms.
