Connection structure of motor and speed reducer
Technical Field
The utility model relates to the technical field of motors, in particular to a connecting structure of a motor and a speed reducer.
Background
The motor is generally connected with the speed reducer on the market at present, but motor and speed reducer generally set up independently respectively, adopt disconnect-type connection structure, after the motor is fixed in speed reducer or carrier through mounting flange, the pivot of motor stretches out from the end cover and stretches into in the speed reducer and be connected with gear assembly after passing the casing of speed reducer again, but this kind of structure can not effectually guarantee the concentricity of motor and speed reducer, noise problem appears easily in the use, can shorten the life of motor simultaneously.
In addition, the connection between the motor and the speed reducer depends on the key of the rotating shaft and the key slot and shaft hole of the speed reducer to bear force, and the force bearing mode is easy to wear.
Therefore, there is a need for an improvement in the connection structure of the existing motor and the speed reducer.

Detailed Description
The following examples illustrate the utility model, but the utility model is not limited to these examples. Modifications and equivalents of some of the technical features of the specific embodiments of the present utility model may be made without departing from the spirit of the present utility model, and they are all included in the scope of the claimed utility model.
Embodiment one: as shown in fig. 1, 2, 3 and 4, the present embodiment provides a connection structure of a motor and a speed reducer, including a motor 1 and a speed reducer 2, where the motor 1 includes a housing 10, a first end cover 11 and a rotating shaft 12, the speed reducer 2 includes a casing 21 and a gear assembly 22, the gear assembly 22 is disposed in the casing 21, a second end cover 23 is integrally formed on the casing 21, one end of the housing 10 is connected with the first end cover 11, the other end is connected with the second end cover 23, the rotating shaft 12 is disposed in the housing 10, one end of the rotating shaft 12 is supported on the first end cover 11, and the other end is supported on the second end cover 23 and extends into the casing 21 to be in transmission connection with the gear assembly 22.
The connecting structure of the motor and the speed reducer can ensure concentricity of the motor and the speed reducer and reduce working noise. Specifically, the second end cover 23 of the motor 1 is disposed on the casing 21 of the speed reducer 2 and is integrally formed with the casing 21, one end of the rotating shaft 12 is supported on the first end cover 11, and the other end of the rotating shaft is supported on the second end cover 23 and extends into the casing 21 to be in transmission connection with the gear assembly 22, so that concentricity of the motor 1 and the speed reducer 2 can be ensured.
In this embodiment, the end of the rotating shaft 12 is provided with the bevel gear 120, the bevel gear 120 is meshed with the gear assembly 22, and compared with the conventional manner that the connection between the motor and the speed reducer relies on the key of the rotating shaft and the key slot and shaft hole of the speed reducer to bear force by adopting the manner that the bevel gear 120 is meshed with the gear assembly 22, the rotating shaft 12 is more wear-resistant and more stable and reliable in use.
In this embodiment, the second end cover 23 is formed on the side surface of the casing 21, the power output end of the gear assembly 22 is disposed on the top surface of the casing 21, and this layout is more reasonable, and the motor 1 and the driven device driven by the speed reducer 2 do not interfere in space position.
Further, bearing chambers 230 are respectively arranged on the inner sides of the centers of the first end cover 11 and the second end cover 23, bearings 13 are arranged in the bearing chambers 230, and two ends of the rotating shaft 12 are respectively supported on the bearings 13.
Preferably, the control box 3 or the junction box is arranged on the shell 10, so that the motor is simple in structure and reasonable in design, the motor can be controlled more conveniently or wired more conveniently, and the use experience of a user is improved.
What has been described above is merely some embodiments of the present utility model. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit of the utility model.
