Description

Technical Field

[0002] A reducer is an independent component consisting of a gear drive, worm drive, or gear-worm drive enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine. It matches the speed and transmits torque between the prime mover and the working machine or actuator. It is widely used in modern machinery and is generally used with a motor to control the output speed of the motor so that the motor can output better and more evenly.

[0003] In the prior art (publication number CN220067119U, patent name is a patent application for a reducer conveniently connected to a motor), the structure is reasonably designed and easy to use.

[0049] The base frame 1 is provided with a clamping assembly 6 and a locking assembly 7 for use with the motor output shaft 3 and the reducer input shaft 5, respectively. A double limiting technology combining clamping and locking is adopted to firmly connect the reducer input shaft and the motor output shaft to improve the stability of the connection.

[0050] like Figure 7-Figure 12 As shown, the clamping assembly 6 includes a first through slot 61 opened on the left side of the top of the base frame 1, and the base frame 1 is provided with slide rails 62 on both sides close to the first through slot 61. The left side of the base frame 1 is rotatably connected with a rotating wheel 63, and the rotating wheel 63 is manually rotated clockwise or counterclockwise to provide a unified driving force, and the right side of the rotating wheel 63 is fixedly connected with a one-way screw rod 64 that rotates with the base frame 1, and a screw rod barrel 65 is threadedly connected to the one-way screw rod 64, and the top of the screw rod barrel 65 is fixedly connected with a connecting seat 66 that slides with the first through slot 61 and is fixed to the motor body 2.

[0051] The locking assembly 7 includes a second through slot 71 opened on the other two sides of the base frame 1 near the first through slot 61, and locking grooves 72 are opened on the motor output shaft 3 and the reducer input shaft 5. The driving bevel gear 68 is meshed with a driven bevel gear 73, and the driving bevel gear 68 and the driven bevel gear 73 are meshed and driven by the driving bevel gear 68 that rotates synchronously with the one-way screw rod 64, and the inner cavity of the driven bevel gear 73 is fixedly connected with a forward and reverse screw rod 74 that rotates with the base frame 1, and both sides of the forward and reverse screw rod 74 are threadedly connected with a screw rod sleeve 75, and the top of the screw rod sleeve 75 is fixedly connected with a connecting frame 76 that slides with the second through slot 71. The connecting frame 7 The top of the inner side of the locking seat 77 is fixedly connected, and the two sets of locking seats 77 are driven to move toward the motor output shaft 3 and the reducer body 4 through the two sets of screw sleeves 75 and the connecting frame 76 on the forward and reverse screw rods 74. The inner side of the locking seat 77 is fixedly connected with a locking protrusion 78 that rotates with the locking groove 72, so that the two sets of semicircular locking protrusions 78 are stuck to the locking grooves 72 reserved for the motor output shaft 3 and the reducer body 4, and will not affect the rotation of the motor output shaft 3 and the reducer body 4, providing a second limit measure for the motor output shaft 3 and the reducer input shaft 5, improving the firmness of their connection to prevent loosening or falling off.

[0052] like Figure 13-Figure 15 As shown, during the connection between the motor output shaft 3 and the reducer input shaft 5, most of them do not have a protective function, cannot perform dust and noise prevention treatment on the work site, and have relatively simple functionality. A protective component 8 used in conjunction with the clamping component 6 and the locking component 7 is provided on the chassis 1, and the protective component 8 includes a bevel gear frame 81 meshed with the other side of the driven bevel gear 73 and rotated with the chassis 1, and a differential bevel gear 82 is meshed on the other side of the bevel gear frame 81, and a threaded rod 83 is fixedly connected to the top of the differential bevel gear 82, and a threaded cylinder 84 is threadedly connected to the threaded rod 83. The driven bevel gear 73 drives the threaded rod 83 on the differential bevel gear 82 to rotate forward or reversely through the bevel gear frame 81, and the threaded rod 83 drives the threaded cylinder 84 to move upward or downward;

[0053] The top of the threaded tube 84 is fixedly connected to a fixing seat 85 fixedly matched with the protective cover 9 through a bearing, and the protective cover 9 is fixedly connected to a light rod tube 86 on all sides, and the base frame 1 is fixedly connected to a light rod 87 slidably plugged with the light rod tube 86 on all sides.

[0054] A working principle of a reducer that is convenient for connecting with a motor: first, hold the rotating wheel 63 tightly and synchronously drive the one-way screw 64 to rotate, the one-way screw 64 drives the screw barrel 65 to move forward accordingly, and the screw barrel 65 drives the connecting seat 66 to slide forward in the first through groove 61, and under the cooperation of the two sets of slide rails 62 and the slider 67 for sliding support of the connecting seat 66, the connecting seat 66 drives the motor output shaft 3 on the motor body 2 to move toward the reducer body 4, until the reserved slot 21 of the motor output shaft 3 is clamped to the surface of the flat key 22 on the reducer input shaft 5 and completely covered in place, thus completing the first clamping and fixing work of the motor output shaft 3 and the reducer input shaft 5;

[0055] When the one-way screw 64 rotates, it also drives the driving bevel gear 68 to rotate synchronously. The driving bevel gear 68 drives the forward and reverse screws 74 on the driven bevel gear 73 to rotate accordingly. The forward and reverse screws 74 drive the two sets of screw sleeves 75 to move synchronously inward. The two sets of screw sleeves 75 drive the two sets of connecting frames 76 to slide synchronously inward in the second through groove 71. The two sets of connecting frames 76 drive the two sets of semicircular locking seats 77 to move toward the motor output shaft 3 and the reducer input shaft 5 in the clamped and fixed state until the locking protrusions 78 in the two sets of semicircular locking seats 77 fit into the locking grooves 72 reserved for the motor output shaft 3 and the reducer input shaft 5, completing the second locking and fixing work for the motor output shaft 3 and the reducer input shaft 5;

[0056] When the driven bevel gear 73 rotates, it also drives the bevel gear frame 81 to rotate synchronously. The gear at the other end of the bevel gear frame 81 drives the differential bevel gear 82 to rotate accordingly. The differential bevel gear 82 drives the threaded rod 83 to rotate accordingly. The threaded rod 83 drives the threaded cylinder 84 to move downward. With the cooperation of the light rod cylinder 86 and the light rod 87 to slide the protective cover 9, the threaded cylinder 84 drives the protective cover 9 to move downward through the fixed seat 85.

[0057] The protective cover 9 also drives the telescopic sleeve 10 and the frame 11 to move down as a whole until they are on the bottom frame 1. At this time, the control circuit breaker 12 is turned on and the electromagnet 13 is energized. The electromagnet 13 is adsorbed on the metal back cover of the motor body 2. The slide groove 14 and the slide bar 15 first cooperate with the frame 11 to slide and support the frame 11. Then, the motor body 2 drives the telescopic sleeve 10 to telescope through the frame 11 on the electromagnet 13. The dust and noise prevention work of the motor body 2 and the reducer body 4 on the bottom frame 1 is completed through the protective cover 9, the telescopic sleeve 10 and the frame 11.

[0058] When the motor output shaft 3 and the reducer input shaft 5 are doubly firmly connected, the motor body 2 drives the reducer input shaft 5 on the reducer body 4 to rotate through the motor output shaft 3, and the locking grooves 72 reserved on the motor output shaft 3 and the reducer input shaft 5 fit the locking protrusions 78 in the two sets of semicircular locking seats 77 to rotate, and the reducer input shaft 5 drives the input cylindrical gear 18 to rotate in the reducer upper end cover 16 and the reducer lower end cover 17, and the input cylindrical gear 18 drives the reducer output shaft 20 to change speed and rotate through the output differential gear 19, thereby completing the speed control work of the reducer body 4 on the motor body 2 after connection.
