Abstract
A cam mechanism for use in a mowing machine. The cam mechanism is comprised of a spur gear and protruding eccentric cams from the top and bottom surfaces of the spur gear. The cam mechanism is formed from a half blanking press process. The eccentric cams are symmetrically formed around a shaft hole located in the center of the spur gear. Members with a hole equaling that of the eccentric cam and shaft hole point symmetry are then fitted onto the eccentric cam. The members are then capable of reciprocation with a phase differential of 180 degrees of each other. The concave portion of the eccentric cam permits lubricants to be filled in the space facilitating the smooth operation of the cam mechanism.
