Description

Technical Field

[0001] The utility model relates to the field of speed reducers, and particularly relates to a speed reducer with an adjustable center coupling. Background Technique

[0002] A speed reducer is an independent component composed of gear transmission, worm transmission, or gear-worm transmission enclosed in a rigid housing, and is commonly used as a speed reduction transmission device between a prime mover and a working machine. Its main function is to match the speed and transmit torque between the prime mover and the working machine or actuator, so as to achieve the transmission of low speed and large torque. The application of speed reducers is very extensive, involving many fields such as food and light industry, electric power, construction, and cement machinery. In modern machinery, the speed reducer is an indispensable key component, and its performance and quality directly affect the operation effect and service life of the entire mechanical equipment.

[0003] During use, the speed reducer is connected to the drive shaft of the equipment through a coupling. When the coupling is installed, one end is connected to the output shaft of the speed reducer, and the other end is connected to the drive shaft of the equipment; when using a conventional coupling, it is necessary to ensure that the output shaft of the speed reducer is coaxial with the drive shaft of the equipment. However, in the actual installation process, the output shaft of the speed reducer and the drive shaft of the equipment cannot be aligned at one time, and multiple groups of bolts need to be connected during the installation process, making the installation inconvenient. Therefore, a speed reducer with an adjustable center coupling is proposed. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a speed reducer with an adjustable center coupling, which can effectively solve the problems mentioned in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A speed reducer with an adjustable center coupling includes a speed reducer base. Positioning through holes are opened at the four corners of the bottom of the speed reducer base. A speed reducer body is fixedly installed on the speed reducer base. An input shaft is provided on one side of the speed reducer body, and an output shaft is provided on the other side of the speed reducer body. A coupling assembly is connected to the output shaft. The coupling assembly includes an input end fixedly connected to the output shaft. An adjustment collar is fixedly installed on the input end. A cross adjustment port is provided in the adjustment collar. A cross pin is movably installed in the cross adjustment port. A docking shaft is fixedly installed on the cross pin. An output end is fixedly installed on the docking shaft. A connection mechanism is provided between the adjustment collar and the output end. The connection mechanism includes a first threaded sleeve connected to the output end. A limit ring seat is fixedly installed on the first threaded sleeve. A second threaded sleeve is connected to the adjustment collar. An installation notch is opened on the second threaded sleeve. A buffer rubber ring is provided between the first threaded sleeve and the second threaded sleeve, and the buffer rubber ring can slow down the impact force between the first threaded sleeve and the second threaded sleeve.

[0007] Furthermore, the coupling assembly further includes positioning key grooves formed on the input end and the output end.

[0008] Furthermore, a key pin is provided in the positioning key groove of the input end, and the input end is restricted on the output shaft of the reducer body by the key pin, and the output shaft can drive the drive shaft of the device to rotate.

[0009] Furthermore, the cross pin is movably installed in the cross adjustment port of the adjustment collar through the cross adjustment port, and there is sufficient clearance between the cross pin and the cross adjustment port. The output end is connected to one end of the adjustment collar through the cross pin, and the input shaft can drive the adjustment collar to rotate. After the adjustment collar rotates, it will drive the cross pin to rotate.

[0010] Furthermore, docking threads are provided in both the first threaded sleeve and the second threaded sleeve. The first threaded sleeve is installed on the output end through the docking threads, and the second threaded sleeve is installed on the adjustment collar through the docking threads.

[0011] Furthermore, the first threaded sleeve passes through the second threaded sleeve through the installation notch.

[0012] Furthermore, the limit ring seat on the first threaded sleeve is restricted at one end of the adjustment collar through the second threaded sleeve, and the output end is restricted on the adjustment collar through the second threaded sleeve.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. During use, the input end can be fixed on the output shaft of the reducer body, and the output end can be fixed on the drive shaft of the device. Then, the reducer body can be pushed forward to embed the cross pin into the cross adjustment port, realizing the preliminary connection between the output shaft and the drive shaft of the device. Moreover, the input end can be driven to rotate by the output shaft on the reducer body. After the input end rotates, it will drive the output end to rotate. After the output end rotates, it will drive the drive shaft of the device to rotate.

[0015] 2. When the output shaft and the drive shaft of the device are preliminarily connected, the adjustment collar and the output end are not concentric. At this time, the second threaded sleeve cannot be completely tightened on the adjustment collar. At this time, the user can adjust the position of the reducer body while rotating the second threaded sleeve. When the second threaded sleeve is completely tightened on the adjustment collar, it means that the adjustment collar and the output end are concentric. Moreover, the second threaded sleeve completely tightened on the adjustment collar will press against the limit ring seat on the first threaded sleeve, thereby fixing the output end on the adjustment collar and maintaining concentricity, and then quickly connecting the output shaft on the reducer body with the drive shaft of the device without the user's repeated adjustment.

Specific embodiments

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] As Figure 1 Figure 2 shown, a reducer with an adjustable center coupling includes a reducer base 1, positioning through holes 2 are opened at the four corners of the bottom of the reducer base 1, a reducer body 4 is fixedly installed on the reducer base 1, an input shaft 3 is provided on one side of the reducer body 4, an output shaft 5 is provided on the other side of the reducer body 4, a coupling assembly 6 is connected to the output shaft 5, the coupling assembly 6 includes an input end 601 fixedly connected to the output shaft 5, an adjusting collar 602 is fixedly installed on the input end 601, a cross adjustment opening 606 is provided in the adjusting collar 602, a cross pin 603 is movably installed in the cross adjustment opening 606, a docking shaft 607 is fixedly installed on the cross pin 603, an output end 604 is fixedly installed on the docking shaft 607, and a connection mechanism 7 is provided between the adjusting collar 602 and the output end 604.

[0023] As Figure 3 shown, the coupling assembly 6 includes an input end 601 fixedly connected to the output shaft 5, an adjusting collar 602 is fixedly installed on the input end 601, a cross adjustment opening 606 is provided in the adjusting collar 602, a cross pin 603 is movably installed in the cross adjustment opening 606, a docking shaft 607 is fixedly installed on the cross pin 603, an output end 604 is fixedly installed on the docking shaft 607, and the coupling assembly 6 further includes positioning keyways 605 provided on the input end 601 and the output end 604.

[0024] Specifically, during use, the input end 601 can be fixed on the output shaft 5 of the reducer body 4, and the output end 604 can be fixed on the drive shaft of the device. Then, the reducer body 4 can be pushed forward to embed the cross pin 603 into the cross adjustment port 606, realizing the preliminary connection between the output shaft 5 and the device drive shaft. Moreover, the rotation of the input end 601 can be driven by the output shaft 5 on the reducer body 4. After the input end 601 rotates, it will drive the output end 604 to rotate. After the output end 604 rotates, it will drive the drive shaft of the device to rotate.

[0025] As Figure 4 shown, the connecting mechanism 7 includes a first threaded sleeve 701 connected to the output end 604. A limit ring seat 702 is fixedly installed on the first threaded sleeve 701. A second threaded sleeve 703 is connected to the adjusting sleeve 602. An installation notch 705 is formed on the second threaded sleeve 703. A buffer rubber ring 704 is provided between the first threaded sleeve 701 and the second threaded sleeve 703. Docking threads 706 are provided in both the first threaded sleeve 701 and the second threaded sleeve 703. The first threaded sleeve 701 is installed on the output end 604 through the docking threads 706, and the second threaded sleeve 703 is installed on the adjusting sleeve 602 through the docking threads 706.

[0026] Specifically, when the output shaft 5 and the device drive shaft are preliminarily connected, the adjusting sleeve 602 and the output end 604 are not concentric. At this time, the second threaded sleeve 703 cannot be completely tightened on the adjusting sleeve 602. At this time, the user can adjust the position of the reducer body 4 while rotating the second threaded sleeve 703. When the second threaded sleeve 703 is completely tightened on the adjusting sleeve 602, it means that the adjusting sleeve 602 and the output end 604 are concentric, enabling the output shaft 5 of the reducer to be aligned with the drive shaft of the device at one time. Moreover, the second threaded sleeve 703 that is completely tightened on the adjusting sleeve 602 will press against the limit ring seat 702 on the first threaded sleeve 701, thereby fixing the output end 604 on the adjusting sleeve 602 and maintaining concentricity, and then quickly connecting the output shaft 5 on the reducer body 4 with the drive shaft of the device together, without the need for the user to repeatedly adjust.

[0027] It should be noted that the present utility model is a speed reducer with a self-aligning coupling. During actual use, first, the input end 601 is fixed on the output shaft 5 of the speed reducer body 4, and the output end 604 is fixed on the drive shaft of the device. Then, the speed reducer body 4 can be pushed forward to make the cross pin 603 embed into the cross adjustment port 606, realizing the preliminary connection between the output shaft 5 and the drive shaft of the device. When the output shaft 5 and the drive shaft of the device are preliminarily connected, the adjusting sleeve 602 is not concentric with the output end 604. At this time, the second threaded sleeve 703 cannot be fully tightened on the adjusting sleeve 602. At this time, the user can adjust the position of the speed reducer body 4 while rotating the second threaded sleeve 703. When the second threaded sleeve 703 is fully tightened on the adjusting sleeve 602, it means that the adjusting sleeve 602 is concentric with the output end 604. And the second threaded sleeve 703 fully tightened on the adjusting sleeve 602 will press on the limit ring seat 702 on the first threaded sleeve 701, thereby fixing the output end 604 on the adjusting sleeve 602 and keeping it concentric, and then quickly connecting the output shaft 5 on the speed reducer body 4 with the drive shaft of the device. After that, the speed reducer body 4 can be fixed, and the input end 601 is driven to rotate by the output shaft 5 on the speed reducer body 4. After the input end 601 rotates, it will drive the output end 604 to rotate. After the output end 604 rotates, it will drive the drive shaft of the device to rotate.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
