Description

Technical Field

[0001] This utility model relates to the field of oil pump drive technology, and in particular to an oil pump drive motor that is easy to install. Background Technology

[0002] An oil pump drive motor is an electric motor specifically designed to drive an oil pump. Its core function is to convert electrical energy into mechanical energy to provide a power source for the oil pump, ensuring that the oil pump can continuously and stably deliver oil (such as lubricating oil, hydraulic oil, fuel oil, etc.).

[0003] Currently, oil pump drive motors are core power components in industrial hydraulic systems, vehicle fuel supply systems, and other fields. They are usually connected to the oil pump body through flanges or brackets. Traditional installation has the problem of low shaft alignment accuracy. Specifically, stress is easily generated during the tightening of bolts, causing the motor shaft and pump shaft to be misaligned, resulting in vibration, noise, and abnormal wear, which reduces the service life of the entire equipment. Therefore, we propose an oil pump drive motor that is easy to install. Utility Model Content

[0004] In view of the problem of low shaft alignment accuracy in the installation of existing oil pump drive motors, this utility model is proposed.

[0021] Reference Figures 1-3 An easy-to-install oil pump drive motor is provided. This easy-to-install oil pump drive motor includes a motor body 1. The output end of the motor body 1 is provided with a motor flange 2. The motor flange 2 is integrally formed by casting or CNC machining. The output shaft hole and bearing seat are machined in the center. The end face center of the motor flange 2 is provided with an output shaft 3. The motor flange 2 has an integrally formed guide cone tube 201. The end face of the motor flange 2 is fitted with a mounting connector 5 via a bearing 4 (a 6204 type deep groove ball bearing). The mounting connector 5 has a guide cone groove 501 corresponding to the guide cone tube 201, and the guide cone groove 501 is adapted to the guide cone tube 201. The output shaft 3 passes through and extends out of the mounting connector 5. The end of the mounting connector 5 away from the motor flange 2 is fitted with a mounting flange 6 via an internal hex bolt 7. The mounting flange 6 is fixedly installed on the oil pump body. In application, the integrated guide cone tube 201 and the guide cone groove 501 cooperate to provide an automatic guiding and positioning function during installation, ensuring the initial alignment accuracy of the output shaft 3 and the oil pump body. The addition of the bearing 4 allows for slight adjustments between the mounting connector 5 and the motor flange 2, avoiding shaft offset caused by installation stress.

[0022] Reference Figure 1 and Figure 2 The taper of the outer surface of the guide cone tube 201 matches the taper of the inner cavity of the guide cone groove 501 (tolerance H7 / h6). In application, the taper matching design between the outer surface of the guide cone tube 201 and the inner cavity of the guide cone groove 501 further optimizes the guiding accuracy, reduces friction or jamming caused by taper deviation during installation, and improves centering efficiency.

[0023] Reference Figure 1 and Figure 2 The inner ring wall of bearing 4 is fixedly installed on motor flange 2, and the outer ring wall of bearing 4 is fixedly installed on mounting connector 5. In application, the structure of bearing 4 with the inner ring fixed to motor flange 2 and the outer ring fixed to mounting connector 5 ensures the rotational freedom of mounting connector 5 and restricts axial movement, thus avoiding damage to bearing 4 due to uneven installation force.

[0024] Reference Figure 1 and Figure 2 The end of the mounting connector 5 away from the motor flange 2 has threaded holes 502 that correspond to the internal hexagon bolts 7 and are arranged in a circular array. The threaded holes 502 are threadedly engaged with the internal hexagon bolts 7. In application, the circular array of threaded holes 502 and the internal hexagon bolts 7 make the fastening force of the mounting flange 6 evenly distributed, prevent single-point stress concentration, simplify the installation steps, and reduce human error.

[0025] Reference Figures 1-3 The outer surface of the mounting connector 5 is provided with anti-slip textures 503 arranged in a circumferential array. In application, the anti-slip textures 503 increase the friction of the mounting connector 5 surface, making it easier to maintain stability when manually gripped or operated with tools, and avoiding installation offset caused by slippage.

[0026] Reference Figures 1-3The outer surface of the mounting connector 5 is also provided with operation holes 504 arranged in a circumferential array for inserting a wrench. In application, the design of the operation holes 504 allows the application of leverage by inserting a wrench or other tools to assist in adjusting the angle or position of the mounting connector 5, which is especially suitable for precision installation in confined spaces.

[0027] The working principle of this utility model is as follows: Pre-positioning stage: First, insert the output shaft 3 on the motor body 1 into the input shaft sleeve of the oil pump body to initially suspend the motor body 1. Then, manually rotate and install the connecting piece 5, and use the tapered surface of the guide cone tube 201 and the guide cone groove 501 to automatically correct the coaxiality. Fine-tuning and fixing: Insert the wrench lever through the operating hole 504, fine-tune the angle of the mounting connector 5 to eliminate residual deviation, and then use the hex bolts 7 to alternately screw them into the threaded holes 502 diagonally, increasing the torque in three stages (e.g., the first time 20Nm, the second time 40Nm, and the third time 60Nm) to tighten them and avoid stress concentration. Verification: Manually rotate the motor shaft to check for any jamming, run it under no-load for a period of time, and monitor the vibration value to be ≤2.8mm / s (ISO 10816 standard).

[0028] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
