The gear reduction unit includes first and second side gears, a case, and a pinion gear that is rotatably disposed on a pinion pin. The case is rotatable with the hub.

A drive mechanism for a multi-function food processor with three drive outlets each couplable separately to a food processing component. The drive mechanism comprising: a motor with a motor output shaft disposed at one end of the motor, the motor output shaft comprises a first cone gear of a cone gear set and a worm; a first central drive shaft comprising a second cone gear of the cone gear set that meshes with the first cone gear of the motor output shaft, the first central drive shaft associated with the first drive outlet and the second drive outlet; the second drive outlet associated with the first central drive shaft by a first reduction gear arrangement which comprises a first gear train that meshes with a sun gear sleeved on the first central drive shaft; a second central drive shaft comprising a worm gear driven by the worm of the motor output shaft, the second central drive shaft associated with the third drive outlet; the third drive outlet associated with the second central drive shaft by a second gear reduction arrangement. The overall structure of the drive mechanism is made more compact.

In a bevel gear pair, a first gear (G1) and a second gear (G2) are applied with tooth top modification, and a ratio of a distance (L1b) from a pitch circle (P1) to a starting position (R1) of the tooth top modification to a distance (L1a) from the pitch circle (P1) to a tooth top (T1) in the first gear (G1) is larger than a ratio of a distance (L2b) from a pitch circle (P2) to a starting position (R2) of the tooth top modification to a distance (L2a) from a pitch circle (P2) to a tooth top (T2) in the second gear (G2). Thus, the bevel gear pair that can achieve smooth meshing is provided.

The present disclosure relate to a gear train comprising an input and an output wherein power is transferred between input and output via two or more gears (13) in parallel, such as a planetary gear train. Each of the two or more gears (13) are bevelled, and arranged to rotate about a respective gear shaft (15), and each of the gears (13) are displaceable in the axial direction of its gear shaft (15). An equalizing arrangement (25) is provided that interconnects the gears (13) such that they are subjected to a similar force of application in their respective axial directions.

The disclosure discloses a bevel planetary gear mechanism applied to a stand mixer, including a center bevel gear (2), a first bevel planetary gear (10), a second bevel planetary gear (3), a third bevel planetary gear (4), an internal bevel gear (5) and a bevel planetary gear bracket (11), wherein, the center bevel gear (2) is mounted on a spindle (1); the first bevel planetary gear (10), the second bevel planetary gear (3) and the third bevel planetary gear (4) are all engaged with the center bevel gear (2); the internal bevel gear (5) surrounds the first bevel planetary gear (10), the second bevel planetary gear (3) and the third bevel planetary gear (4) and are engaged with such three gears. By using the bevel planetary gear mechanism provided by the disclosure, the stand mixer has a pitched kneading hook, thereby improving the kneading effect of the stand mixer.

In a bevel gear pair, a first gear and a second gear are applied with tooth top modification, and a ratio of a distance from a pitch circle to a starting position of the tooth top modification to a distance from the pitch circle to a tooth top in the first gear is larger than a ratio of a distance from a pitch circle to a starting position of the tooth top modification to a distance from a pitch circle to a tooth top in the second gear.
