Elevator lifting machine structure

The invention relates to an elevator lifting machine structure. Primarily, a motor unit and a deceleration unit are provided within a motor chamber and a deceleration chamber of a machine body respectively. Furthermore, an input shaft of the motor unit is extended into the deceleration chamber to be assembled with a first helical gear of the deceleration unit. Moreover, a second helical gear on an output shaft within the deceleration chamber is engaged with the first helical gear. The output and input shafts and the first and second helical gears set thereon are set horizontally. When the lifting machine is operated, the radial load is caused by the weight of the carriage, the balance weight, the personnel load, and the reaction force, etc. The noise or premature damage caused by the second helical gear pressing on the first helical gear can be avoided through a main rope wheel acting on the second helical gear. In addition, in the present invention, a detector is installed on a front side of the machine body
