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 in particular relates to a motor base of a pumping unit which is convenient for replacing belts to reduce the position adjustment of the motor. The pulley assembly further includes an inner ring, an outer ring and an intermediate transmission member, the inner ring is fixedly mounted on the output shaft of the motor, a belt groove matching the belt is provided on the outside of the outer ring, and the intermediate transmission member is arranged on the inner ring and the outer ring between, so as to transmit the power of the inner ring to the outer ring; a slide seat is installed on the base, and the slide seat can slide on the base under the drive of the screw, and the intermediate transmission part is installed on the slide seat, and can Driven by the sliding seat, it is pulled out from between the inner ring and the outer ring. The invention adopts a brand-new technical idea, which can replace the belt without moving the motor, and completely solves the problems of poor safety, time-consuming and laborious, low efficiency, and difficult alignment of the pulley caused by the moving motor.

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 replacing belts and reducing motor position adjustment. 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 ...
