Disclosure of Invention
The utility model aims at the above-mentioned problem that exists among the prior art, provide a design more rationally need not change the novel double speed gear motor that manufacturing cost is lower to original gear structure.
The purpose of the utility model can be realized by the following technical proposal: the utility model provides a novel double speed gear motor, includes input gear, pinion, forward gear, reverse gear and output gear, its characterized in that, the input gear cover locate the transmission shaft of motor on and with pinion intermeshing, the pinion cover locate the pivot on and be provided with one-way bearing one, forward gear and change gear one in the pivot on one simultaneously, forward gear and reverse gear intermeshing, the reverse gear cover is located on the pivot two, is provided with change gear two and one-way bearing two in the pivot two simultaneously, wherein change gear one and change gear two all with output gear meshing, output gear's center is provided with the output shaft.
The novel double-speed reducing motor has the following operation modes: the characteristic that the unidirectional bearing can only transmit torque in a unidirectional mode and carry out reverse idle running is adopted, when the motor drives the input gear to rotate in a forward direction, the input gear drives the auxiliary gear, the auxiliary gear drives the forward gear, the first speed change gear runs through the unidirectional bearing, power is transmitted to the output gear through the first speed change gear to enable the output shaft to rotate in the forward direction, and at the moment, the reverse gear, the second unidirectional bearing and the second speed change gear are in an idle running state; and similarly, when the motor drives the input gear to rotate reversely, the first one-way bearing and the first speed change gear are in an idle rotation state, the secondary gear and the forward gear drive the reverse gear to operate, the second one-way bearing drives the second speed change gear, and power is transmitted to the output gear through the second speed change gear to enable the output shaft to rotate reversely.
In the above novel two-speed reduction motor, the number of teeth of the first speed change gear is smaller than the number of teeth of the second speed change gear.
In the novel double-speed reducing motor, the lower end part of the first rotating shaft is fixed on the motor shell.
In the novel double-speed reducing motor, the motor is a synchronous motor.
Compared with the prior art, the double-speed reducing motor has the following advantages: 1. the conventional and universal one-way bearing on the market is used, the structure of the original gear is not required to be improved, the manufacture is more convenient, and the cost is lower; 2. by arranging only one input gear on the transmission shaft of the motor and improving the meshing mode among the gears, the two-speed motor can be more easily installed in terms of volume design under the condition of not changing the power of the motor.
