Description

High-precision planetary reducer integrated with motor

technical field

The utility model relates to a high-precision planetary reducer integrated with a motor.

Background technique

At present, most of the workplaces where servo motors and reducers are used in the market are separate connections between the motor and the precision planetary reducer, which will inevitably increase the overall size of the servo motor and the reducer after the connection. As the space requirements are getting smaller and smaller, it is a trend to make the size of the servo motor or planetary reducer smaller. However, the split connection will still occupy a large equipment installation space, and the accuracy of the whole machine cannot be guaranteed. It is convenient for installation and transportation, which in turn will affect the processing period and production efficiency.

Utility model content

According to the deficiencies in the prior art above, the technical problem to be solved by the utility model is: to provide a high-precision planetary reducer integrated with a motor that solves the above-mentioned defects, improves the working performance, and reduces the occupied space.

The technical solution adopted by the utility model to solve the technical problem is: a high-precision planetary reducer integrated with the motor, including a double-supported planetary frame, a motor rotor shaft, a sun wheel, a planetary wheel and an output spline shaft, and a double-supported planetary frame It is a rotatable structure, and the inner side of the double-supported planetary frame is provided with a ring gear. The end of the motor rotor shaft is in interference connection with the shaft of the sun gear, and the planetary gear is fixed on the double-supported planetary frame. The ring gears of the planet carrier are meshed, and the output spline shaft is connected to the rear end of the double-supported planet carrier.

The output spline shaft and the double-supported planet carrier are of an integral structure. It can improve the working performance of the whole machine.

The principle of use is:

The rotation of the rotor shaft of the motor drives the sun gear to rotate. The planetary gear is fixed on the rotatable double-supported planetary carrier. The sun gear and the planetary gear are driven through gear meshing. The output spline shaft supporting the rear end of the planet carrier rotates. The ring gear is hidden inside the double-supported planet carrier as a whole and fixed by screw connection.

The beneficial effects of the utility model are: the utility model successfully solves the problem that the separate connection between the servo motor and the planetary reducer occupies a large space and the precision is difficult to improve, and the sun gear shaft of the planetary reducer and the motor rotor of the servo motor The shaft is connected as one shaft, and the outer diameter of the ring gear of the reducer is reduced under the condition of ensuring strength and placed inside the double-supported planet carrier, and the planetary reducer is hidden inside the servo motor as a whole, which can not only minimize the The overall dimensions of the servo motor and the planetary reducer, and the rotor shaft of the motor and the sun gear are integrated, so the working performance of the whole machine is also guaranteed.
