Description

Technical Field

[0001] This utility model belongs to the technical field of geared motor equipment, and specifically relates to a geared motor assembly. Background Technology

[0002] A geared motor is a power transmission device that converts the high speed and low torque of an electric motor into low speed and high torque. With the development of industrial automation, machinery manufacturing, and precision control, the technical requirements for geared motors are becoming increasingly stringent.

[0003] The working principle of a geared motor is mainly to reduce speed and increase torque through gears, worm gears, or other transmission mechanisms. The motor input shaft transmits high-speed, low-torque power to the output shaft through the transmission mechanism, and the output shaft outputs higher torque at a lower speed. Different types of geared motors will have different transmission mechanisms and transmission ratios.

[0004] The geared motor must meet the following main technical requirements:

[0005] 1. High transmission efficiency: While ensuring output torque, it minimizes energy loss and improves overall transmission efficiency.

[0006] 2. Compact structure: While meeting performance requirements, the structural design is optimized to reduce volume and weight, making it easy to install and operate.

[0007] 3. Smooth operation: Reduce vibration and noise to ensure smooth and reliable equipment operation.

[0008] 4. Long service life: High-quality materials and advanced manufacturing processes are used to improve product life and maintenance cycle.

[0009] To further meet the requirement of a compact structure, this application provides a geared motor assembly. This assembly connects the front end of the geared motor to the outer casing of the gearbox via a composite motor front cover to complete the installation process. Compared with the conventional geared motor structure, this structure eliminates the installation connecting bushing between the outer casing and the geared motor. Eliminating the bushing further reduces the length of the drive shaft and also reduces the load after the drive shaft is extended. The composite electrode front cover of this application adopts a double-layer contact end face structure, which can simultaneously mate with the motor end and the outer casing, placing the worm gear components inside the outer casing, reducing the probability of internal structure contact with the external environment. The double-layer end face composite electrode front cover structure can be machined into a single piece, resulting in a simplified structure and high strength. Summary of the Invention

[0013] Furthermore, the motor front cover includes a front end cover layer and a rear end cover layer;

[0034] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a geared motor assembly includes a motor, a fan cover, and an extension seat. A fan cover 1 is installed at the rear end of the motor 2 along the fan position. A terminal box 9 is fixedly installed on the side of the motor 2. A front cover 8 is installed at the front end of the motor 2. A mating seat 3 is fixedly connected to the front end of the front cover 8 via mounting bolts. An extension seat 7 integrally extends from the front end of the mating seat 3. The front end cover layer 8-1 and the rear end cover layer 8-3 form an integral connection mechanism. The main viewing end face of the front end cover layer 8-1 matches and mates with the mating end face of the mating seat 3. The main viewing end face dimensions of the rear end cover layer 8-3 match and mate with the front end of the motor 2. The front cover 8 includes a front end cover layer 8-1 and a rear end cover layer 8-3. The fan cover 1 is installed on the outside of the fan at the rear end of the motor 2 to filter impurities and prevent dust accumulation in the motor fan and internal components. The motor front cover 8, as a double-layer contact end-face structure, shortens the connection distance between the motor 2 and the outer extension seat 7, and saves on the intermediate connecting bushing. This composite electrode front cover 8 structure allows for a simplified, integrated machining process on both sides, directly exposing the mating end faces of the motor 2 and the outer extension seat 7. The installation process of the motor 2 and the outer extension seat 7 is completed using synchronous mounting holes and mounting bolts. The mating seat 3, as an integrated connection structure of the outer extension seat 7, can be used to complete the transmission installation of the internal worm gear of the geared motor.

[0036] The extended base 7 is integrally connected to a non-standard bearing housing 6. The non-standard bearing housing 6 serves as the bearing housing structure for interfacing with external equipment. The non-standard bearing housing 6, through its simplified sleeve shape, works in conjunction with the extended base 7 to reduce counterweight and thus lower the overall load on the geared motor.

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the front end cover 8-1 and the rear end cover 8-3 are provided with six sets of mounting through holes. The mounting through holes are synchronously connected along the front end cover 8-1 and the rear end cover 8-3. The front end cover 8-1 and the rear end cover 8-3 are provided with a drive shaft hole 8-2 at their center.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the top of the outer extension seat 7 has a vent hole, and a vent cap 7-2 is installed on top of the vent hole; the vent cap 7-2 can balance the internal and external pressures and can be opened to release air when necessary. It also prevents internal lubricating oil leakage and the intrusion of harmful substances, facilitating later maintenance.

[0039] The irregularly shaped bearing seat 6, integrally connected to the inner side of the outer extension seat 7, houses a bearing 4 at its center. The bearing 4 has a key shaft hole 5 at its center. The key shaft hole 5 is designed to accommodate a transmission key shaft for power transmission in conjunction with external equipment.

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a heat dissipation cavity is reserved between the outer extension seat 7 and the irregular bearing seat 6; the design of the heat dissipation cavity is to cooperate with the vent cap 7-2 on the top to complete the exhaust and stabilize the internal pressure.

[0041] The outer ring of the irregular bearing housing 6 has four sets of extended mounting ends 6-1, which are arranged in a ring array. Each set of extended mounting ends 6-1 has a blind mounting hole. The outer end of each extended mounting end 6-1 is integrally connected to the inner wall of the outer bearing housing 7. The extended mounting ends 6-1 are used to further connect and install external equipment with the irregular bearing housing 6, preventing asynchronous vibration of the equipment and improving the stability of the overall structure.

[0042] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the outer extension seat 7 has positioning grooves 7-1 along its front end face and bottom end face. The positioning grooves 7-1 also serve as positioning structures for later installation.

[0043] It should be noted that the above content merely illustrates the technical concept of this utility model and cannot be used to limit the scope of protection of this utility model. For those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and all such improvements and modifications fall within the scope of protection of the claims of this utility model.
