Abstract

The invention relates to a dual-motor transmission structure which comprises a spindle, a spindle gear and a driving wheel set sequentially connected, wherein the driving wheel set comprises at leasttwo conveying wheel sets; every two adjacent conveying wheel sets are in drive joint; each of the conveying wheel sets comprises a first gear shaft, a second gear shaft, a first plate gear connected with the first gear shaft, and a second plate gear connected with the second gear shaft; the first gear shaft and the second gear shaft are symmetrically arranged on the two sides of the spindle; and afirst secondary gear shaft and a second secondary gear shaft are arranged between the spindle and the plane of a first primary gear shaft and a second primary gear shaft. The invention further relates to a wall cutting machine provided with the dual-motor transmission structure. The dual-motor transmission structure can increase the torque and the output speed, reduces the size and prolongs the service life.

Description

technical field [0001] The invention relates to a transmission structure of double motors and a wall cutting machine with the transmission structure. Background technique [0002] The wall cutting machine is a machine for cutting concrete walls, but the pressure of the existing wall cutting machine is on one side of the gear for a long time, which leads to serious mechanical wear of the gear bearings, and also causes the machine to Stuck and smoldering, low efficiency, small output torque, slow cutting speed, short service life and high labor cost. The power of a motor is usually small (3.5KW), the output torque is small (80KN ~ 85KN), and the cutting speed is slow (2M ~ 2.5M / h). If the power of the motor is increased, a huge cost is required, and the improvement of torque and cutting speed is also limited. [0003] If two motors are installed to increase the power, on the one hand, the power of the two motors needs to be synchronized. In addition, since the two motors are...
