Description
Technical Field
The utility model relates to a mute quick connection structure of a motor output shaft, belonging to the technical field of motors.
Background
When the output shaft of the driving motor rotates, the gear on the motor shaft drives the reduction gear in the reduction gear box to rotate, so that the effects of reducing the rotating speed and increasing the torque are achieved.
The motor shaft is supported in the motor by two bearings, and when the motor output gear shaft is meshed with the gear in the reduction gear box, the motor shaft is fixed by the bearings in the gear box because the motor shaft is longer in extension length, so that the motor output shaft strength is increased, and the motor output shaft is not bent when stressed.
But the motor shaft is fixed for three bearings just to the inside bearing of fixed motor shaft in the gearbox that adds of motor this moment, and its straightness nature is hardly realized to its three bearings, appears when leading to three bearings fixed motor shaft: the noise is high, the rotation is not smooth, the phenomenon of dull rotation is easy to occur, the transmission efficiency is low, the processing difficulty is increased for ensuring the fixed linearity of the three bearings, the processing technology is complex, and the precision cannot be guaranteed.
SUMMERY OF THE UTILITY MODEL
Aiming at the problems in the prior art, the utility model provides the mute quick connection structure of the motor output shaft, which improves the transmission efficiency, reduces the noise and prolongs the service life of the machine body.
In order to achieve the purpose, the utility model adopts the technical scheme that: the motor output shaft mute quick connection structure comprises a motor, a motor shaft, a high-speed gear shaft, a straight-tooth internal spline, a straight-tooth external spline and a reduction gear box;
the motor shaft is fixed on the motor through a bearing, and a straight-tooth internal spline is arranged on the motor shaft;
the high-speed gear shaft is arranged on the reduction gear box through a bearing, and the high-speed gear shaft is provided with a straight tooth external spline;
the straight-tooth internal spline and the straight-tooth external spline are mutually matched to realize the connection and the separation of the motor and the reduction gear box.
Further, the number of bearings on the motor is 2.
Further, the reduction gear box has 2 bearings.
The utility model has the beneficial effects that:
after the motor is connected with the speed reducing mechanism, the straight-tooth internal spline at the end part of the motor is matched with the straight-tooth external spline of the speed reducing mechanism, so that quick connection and separation can be realized; after the inner spline and the outer spline of the involute are matched, high-precision connection can be realized by utilizing the self-aligning function of the involute.
The motor shaft realizes the fixation of two bearings on the motor, and the high-speed gear shaft of the speed reducing mechanism is also fixed by the two bearings, so that the fixation and the rotation of the motor shaft or the high-speed gear shaft of the speed reducing mechanism are quite flexible and smooth, the phenomena of stiff rotation and the like when one shaft is fixed by the three bearings can not be generated, the transmission efficiency is improved, the noise is reduced, and the service life of the machine body is prolonged.
