Problems solved by technology

[0005] 1. The motor used on the pumping unit is a heavy-duty motor, which is large in size and weighs hundreds of kilograms, and it is very laborious to move
[0006] 2. There are many bolts used to fix the motor, which need to be disassembled one by one before and after installation, and the motor position needs to be adjusted repeatedly when moving the motor
These factors make the process of changing belts too time-consuming and inefficient
[0007] 3. Due to the difference in the quality of workers, after replacing the belt, the tightening torque of the bolts used to fix the motor is often not up to standard, resulting in a slight displacement of the motor under the action of running vibration. After the motor is displaced, the relative position between the two pulleys If it is changed, it will seriously affect the transmission efficiency of the belt drive mechanism and will increase the wear of the belt

Embodiment 1

[0038] like figure 1 As shown, this embodiment includes a base plate 1 and a belt 5 wheel assembly, the motor 2 is fixedly installed on the base plate 1 , and the belt 5 wheel assembly is installed on the output shaft 9 of the motor 2 .

[0039] Compared with simply installing the belt 5 wheel on the output shaft 9 of the motor 2 in the traditional technology, the belt 5 wheel and the motor 2 are installed on the base at the same time through the sliding seat 3, so that the sliding seat 3 shares the output of the belt 5 wheel to the motor 2. The lateral pulling force exerted by the shaft 9 greatly prolongs the service life of the bearings in the motor 2 , thereby greatly reducing a large amount of maintenance costs caused by replacing the bearings of the motor 2 . Specifically, the traditional belt 5 wheel installation method makes the strong tensile load applied when the belt 5 transmits power always act on one side of the output shaft 9 of the motor 2, forming a large bendin...

Embodiment 2

[0044] The difference between this embodiment and Embodiment 1 lies in the structure of the intermediate transmission member.

[0045] like figure 2 As shown, in this embodiment, the intermediate transmission member is a supporting gear 11, and the supporting gear 11 is installed on the sliding seat 3 through the gear shaft 10 and can rotate on the gear shaft 10. The outer side of the inner ring 8 and the inner side of the outer ring 6 are connected with the supporting gear 11 through gear meshing. Compared with Embodiment 1, this structure can effectively provide a certain deceleration function, which is beneficial to increase the transmission ratio between the motor 2 and the reducer.

Embodiment 3

[0047] The difference between this embodiment and the second embodiment is that the number of supporting gears 11 is limited, and one of the supporting gears 11 (ie, the active gear 17 ) adopts a special movable installation structure.

[0048] like Figure 4 As shown, there are two supporting gears 11 , and the two supporting gears 11 are arranged symmetrically on the outer side of the inner ring 8 .

[0049] The sliding seat 3 is equipped with a rotating seat 15 that can rotate around the centerline of the output shaft 9 of the motor 2, and the two supporting gears 11 are respectively called a fixed gear 18 and a movable gear 17, wherein the fixed gear 18 is located The gear shaft 10 is fixedly installed on the sliding seat 3, and the gear shaft 10 where the movable gear 17 is located is fixedly installed on the rotating seat 15;

[0050] An arc-shaped hole 19 is provided on the sliding seat 3 corresponding to the gear shaft 10 of the movable gear 17 .

[0051] Two support...

Abstract

The invention belongs to the field of pumping unit equipment, and particularly relates to a pumping unit motor base convenient for belt replacement, which comprises a bottom plate and a belt pulley assembly, a motor is fixedly mounted on the bottom plate, and the belt pulley assembly is mounted on an output shaft of the motor. The belt pulley assembly further comprises an inner ring, an outer ring and a middle transmission part, the inner ring is fixedly installed on an output shaft of the motor, a belt groove matched with the belt is formed in the outer side of the outer ring, and the middle transmission part is arranged between the inner ring and the outer ring, so that power of the inner ring is transmitted to the outer ring. A sliding seat is installed on the base and can slide on the base under the driving of the lead screw, and the middle transmission part is installed on the sliding seat and can be pulled out between the inner ring and the outer ring under the driving of the sliding seat. A brand new technical thought is adopted, the belt can be replaced under the condition that the motor is not moved, and the problems that when the motor is moved, safety is poor, time and labor are wasted, efficiency is low, and a belt pulley is not prone to being aligned are thoroughly solved.

Description

technical field [0001] The invention belongs to the field of pumping unit equipment, and in particular relates to a motor base of a pumping unit which is convenient for belt replacement. Background technique [0002] Both the motor and the reducer are important components of the pumping unit. Pulleys are respectively installed on the output shaft of the motor and the input shaft of the reducer. A belt is sheathed on the outside of the two pulleys. The power of the motor is transmitted to the reducer through the belt. [0003] The belt between the motor and the reducer is a vulnerable part and needs to be replaced frequently. The belt used on the pumping unit is a wide ganged belt. Reduce the distance between the two pulleys by certain means to loosen the belt and remove the old belt, and then put the new belt on the two pulleys to restore the distance between the pulleys, thereby tensioning the new belt. [0004] At present, the method of moving the motor is usually used to...
