The utility model discloses a high-torque coffee
machine motor which comprises a motor body, a speed
reducer shell, a four-head worm, a worm gear, a first bearing, a second bearing, a transmission shaft and a locking screw. A
motor shaft of the motor body is connected with the four-head worm, the worm gear is connected with the four-head worm in a rotary meshing mode, and the transmission shaft is sequentially provided with an outer
tooth part, a stopping part and an outer thread part at intervals in the axial direction of the transmission shaft. The
motor shaft of the motor body is connected with the four-head worm, the worm is installed in the first containing cavity, the worm gear is installed in the second containing cavity, when the motor body rotates, the worm gear can be driven by the four-head worm to achieve meshing
speed reduction transmission, and compared with a single-head worm, the four-head worm has the advantages that the worm gear can be driven by the four-head worm to achieve meshing
speed reduction transmission; the worm gear can be driven to rotate faster at the same rotating speed, so that the transmission speed is increased, the coffee
machine motor can realize high-rotating-speed transmission and can keep high-torque output, and the requirement of efficient and stable operation of the coffee
machine under the high-load working condition is met.
