Description

Technical Field

[0001] The present application relates to the field of oil pump motors, and in particular to an end cover for an oil pump motor. Background Art

[0002] In the hydraulic system, the design of the quick-release coupling structure of the oil pump motor is crucial to the performance of the entire system. The end cover, as a key component of the coupling structure, undertakes many important functions. The end cover not only needs to protect the inside of the motor from the invasion of the external environment, such as dust, moisture and other pollutants, but also must ensure the fixation and precise alignment of the coupling during installation and operation. The design quality of the end cover directly affects the installation efficiency, operation stability and convenience of maintenance of the system.

[0003] Traditional limitations of end cap design

[0004] In the traditional design of oil pump motor coupling, the end cover mainly focuses on its basic sealing and fixing functions. Although this design meets the basic protection needs to a certain extent, it has some shortcomings in actual operation.

[0005] Specifically, the structure of most traditional end caps is not optimized for fast and accurate assembly. Especially in situations where precise alignment of the coupling with the oil pump and motor shaft is required, there is a lack of design features for quick docking and fixing. This results in time-consuming installation work and often requires additional manpower and technical input, which increases the overall installation cost.

[0006] In addition, without the design support that facilitates quick and accurate alignment, traditional end covers often make it difficult to ensure perfect docking between the coupling and the motor shaft. This improper alignment may cause additional wear, noise or even failure of the coupling during operation, affecting the overall stability and efficiency of the system.

[0007] More importantly, traditional end cover designs usually consider structural robustness more than maintenance convenience. Once the motor or coupling requires maintenance and overhaul, the process of removing and reinstalling the end cover is complicated and time-consuming, which not only prolongs the system downtime but also increases maintenance costs.

[0008] In view of the importance of the end cover in the oil pump motor coupling structure and the limitations of traditional design, it is particularly necessary to improve the design. Utility Model Content

[0009] The purpose of the present application is to overcome a shortcoming of the prior art and to provide an end cover for an oil pump motor, the end cover having a preset installation window, which is convenient for aligning and connecting the oil pump motor and the coupling when connected, so as to ensure fast and precise docking between the coupling and the motor shaft.

[0010] To achieve the above-mentioned purpose, the present application discloses an end cover for an oil pump motor, comprising an end cover body, a connection channel for connecting the output shaft of the oil pump motor is provided in the center of the end cover body; an inwardly concave mounting position is provided on the front of the end cover, and an annular sealing groove is provided in the bottom surface of the mounting position, and the annular sealing groove facilitates the sealing when the motor and the coupling are matched; a plurality of positioning slots are also provided on the front of the end cover body, and the motor and the external mechanism are quickly positioned and connected through the slots; the end cover body is provided with at least one observation window connected to the connection channel on the side.

[0011] Furthermore, the observation window is sealed by a detachable sealing plug under normal conditions.

[0012] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0013] 1. The annular sealing groove in the end cover provides a good seal between the motor and the coupling. This sealing design can effectively prevent liquid leakage and enhance the reliability and durability of the equipment in various working environments.

[0014] 2. The concave mounting position of the end cover and the annular sealing groove on the bottom not only simplify the assembly process, but also make replacement and maintenance more convenient. This design can reduce the downtime of the machine and reduce maintenance costs.

[0015] 3. The positioning slot on the front of the end cover allows the motor to be quickly and accurately positioned and connected to the external mechanism. This quick positioning function is particularly beneficial for application scenarios that require frequent assembly and disassembly, improving work efficiency.

[0016] 4. There is at least one observation window on the side of the end cover, which can be closed or opened by a removable sealing plug, so that users can observe and inspect the internal condition of the motor. Through this design, operators can more easily identify and solve possible problems and improve the operating stability of the equipment.

[0017] In summary, the design of the end cover for the oil pump motor significantly improves the overall performance and ease of use of the equipment by improving the sealing effect, simplifying the installation and maintenance process, speeding up the positioning and connection of components, and providing a convenient maintenance inspection window. These improvements are of great significance to improving the operating efficiency of the equipment and reducing long-term operating costs. BRIEF DESCRIPTION OF THE DRAWINGS
