Description

Technical Field

[0001] The utility model relates to the technical field of right-angle reducers, in particular to a right-angle reducer with a gear position fine-tuning structure. Background Art

[0002] A reducer is an independent, closed transmission device between the prime mover and the working machine, used to reduce speed and increase torque to meet operating requirements. A reducer uses transmission components (typically gears or worms) to convert the higher speed of the input shaft to a lower speed of the output shaft. To prevent deterioration in the meshing state between the bevel gears due to vibration or wear after a period of operation, a mechanism for fine-tuning the gear position is typically installed within the reducer. This is usually achieved by providing a push mechanism to change the gear position.

[0003] However, the adjustment structure of the existing right-angle reducer with a gear position fine-tuning structure usually needs to be completed manually. This requires that the casing of the right-angle reducer needs to be disassembled in actual use, and then the push structure is manually adjusted to fine-tune the position of the gear. This process tests the operator's operating level and is difficult to operate.

[0004] To this end, we designed a right-angle reducer with a gear position fine-tuning structure to solve the above problems. Utility Model Content

[0005] The purpose of the present utility model is to provide a right-angle reducer with a gear position fine-tuning structure to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the utility model provides a right-angle reducer with a gear position fine-tuning structure, comprising a right-angle housing, two first bearings and a second bearing fixedly mounted at both ends of the right-angle housing, and an input shaft and an output member fixedly plugged into the inner rings of the first and second bearings, one end of the input shaft is fixedly sleeved with a first bevel gear, one end of the output member is slidably provided with a second bevel gear, one end of the second bevel gear is fixedly mounted with a slide column, and the slide column is slidably plugged into one side of the output member, and further comprising:

[0007] The fixed plate is fixedly installed in the right-angle housing and movably sleeved on the output member;

[0008] The micro electric push rod has two ends which are respectively slidably mounted and fixedly mounted between the fixed plate and the second bevel gear, and is used for electrically driving the position of the second bevel gear.

[0009] Furthermore, an annular groove is provided on one side of the fixing plate, and an end of the micro electric push rod away from the second bevel gear is slidably inserted into the annular groove.

[0010] Furthermore, there are two micro electric push rods, and the two micro electric push rods are symmetrically arranged between the fixed disk and the second bevel gear.

[0011] Furthermore, a sliding groove is provided on one side of the output member, and the sliding post is slidably inserted in the sliding groove.

[0012] Furthermore, two guide rails are symmetrically provided in the slide groove, and balls are rotatably mounted on the top and bottom of the slide column, and the balls are rollingly connected in the guide rails.

[0013] Furthermore, a right-angle cavity is defined in the right-angle housing, a blocking member is fixedly installed in the right-angle cavity, and the input shaft is rotatably inserted in the blocking member.

[0014] Furthermore, flanges are fixedly mounted on both ends of the right-angle housing, and threaded holes are provided in the flanges for threaded insertion of screws.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By turning on the micro electric push rod, the driving end of the micro electric push rod can push the second bevel gear and the slide column to slide inward and outward of the output member, thereby achieving the effect of electrically adjusting the position of the second bevel gear, thereby avoiding the problem that the second bevel gear cannot be perfectly meshed with the first bevel gear due to mechanical wear such as vibration. It should be noted that during the rotation of the second bevel gear, the second bevel gear will drive the micro electric push rod to slide in the annular groove, thereby avoiding the problem of motion interference;

[0016] 2. When the slide column slides in the slide groove, the ball will roll in the guide rail, which can change the sliding friction of the slide column into rolling friction, reducing the friction force and friction loss at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-4 The utility model provides a technical solution: a right-angle reducer with a gear position fine-tuning structure, comprising a right-angle housing 1, two first bearings 2 and a second bearing 3 fixedly mounted at both ends of the right-angle housing 1, and an input shaft 4 and an output member 5 fixedly plugged into the inner rings of the first bearing 2 and the second bearing 3, one end of the input shaft 4 is fixedly sleeved with a first bevel gear 6, one end of the output member 5 is slidably provided with a second bevel gear 7, one end of the second bevel gear 7 is fixedly mounted with a slide post 11, and the slide post 11 is slidably plugged into one side of the output member 5, and further comprising,

[0024] The fixed plate 8 is fixedly mounted in the right-angle housing 1 and movably sleeved on the output member 5;

[0025] A micro electric push rod 9 is slidably mounted and fixedly mounted at both ends between the fixed disk 8 and the second bevel gear 7, and is used to electrically drive the position of the second bevel gear 7. An annular groove 10 is provided on one side of the fixed disk 8, and the end of the micro electric push rod 9 away from the second bevel gear 7 is slidably inserted into the annular groove 10. A slide groove 12 is provided on one side of the output member 5, and the slide column 11 is slidably inserted into the slide groove 12.

[0026] During specific implementation, the driving end of the motor is fixedly connected to the input shaft 4, and then the output member 5 is fixedly connected to the shaft body to be transmitted. At this time, the motor is turned on, and the driving end of the motor can drive the input shaft 4 to rotate, so that the first bevel gear 6 and the second bevel gear 7 are meshed and drive the output member 5 and the shaft body to rotate, which can achieve the effect of decelerating the driving end of the motor;

[0027] In addition, when the position of the second bevel gear 7 needs to be adjusted, the micro electric push rod 9 is turned on at this time, so that the driving end of the micro electric push rod 9 pushes the second bevel gear 7 and the slide column 11 to slide inward and outward of the output member 5, thereby achieving the effect of electrically adjusting the position of the second bevel gear 7, and avoiding the problem of the second bevel gear 7 not being able to perfectly mesh with the first bevel gear 6 due to mechanical wear such as vibration. It should be noted that during the rotation of the second bevel gear 7, the second bevel gear 7 will drive the micro electric push rod 9 to slide in the annular groove 10, which can avoid the problem of motion interference.

[0028] See Figure 1-4 As shown, there are two micro electric push rods 9, and the two micro electric push rods 9 are symmetrically arranged between the fixed plate 8 and the second bevel gear 7. The arrangement of the two micro electric push rods 9 can ensure the stability of the second bevel gear 7 when sliding, and avoid the problem of the second bevel gear 7 tilting.

[0029] See Figure 1-4 Two guide rails 13 are symmetrically arranged in the chute 12. Ball bearings 14 are rotatably mounted on the top and bottom of the slide post 11. The balls 14 roll in the guide rails 13. As the slide post 11 slides in the chute 12, the balls 14 roll in the guide rails 13, converting the sliding friction of the slide post 11 into rolling friction, thereby reducing friction and friction loss.

[0030] See Figure 1-4 A right-angle cavity 16 is provided in the right-angle housing 1, a blocking member 15 is fixedly installed in the right-angle cavity 16, and the input shaft 4 is rotatably inserted in the blocking member 15. The first bearing 2 can be blocked.

[0031] See Figure 1-4 The right angle housing 1 is fixed with flanges 17 at both ends, and threaded holes are provided in the flanges 17 for threaded screws. This allows for quick installation of the right angle reducer.

[0032] In addition, it should be noted that, for the first bevel gear 6 and the second bevel gear 7, we can set the diameter of the first bevel gear 6 to be smaller than the second bevel gear 7, so that when the first bevel gear 6 rotates, the second bevel gear 7 can rotate slowly, thereby ensuring the deceleration effect of the right-angle reducer.

[0033] In addition, as the micro electric push rod 9 slides in the annular groove 10, in order to prevent the micro electric push rod 9 from slipping out of the annular groove 10, we can set a convex edge (not shown in the figure) on the outer side of the micro electric push rod 9, and then open a card slot (not shown in the figure) in the annular groove 10, and slide the convex edge into the card slot to limit the micro electric push rod 9 so that the micro electric push rod 9 can only slide along the inner circle of the annular groove 10.

[0034] Working principle: When in use, the driving end of the motor is fixedly connected to the input shaft 4, and then the output member 5 is fixedly connected to the shaft body to be driven. At this time, the motor is turned on, and the driving end of the motor can drive the input shaft 4 to rotate, so that the first bevel gear 6 and the second bevel gear 7 are meshed and drive the output member 5 and the shaft body to rotate, which can achieve the effect of decelerating the driving end of the motor;

[0035] In addition, when the position of the second bevel gear 7 needs to be adjusted, the micro electric push rod 9 is turned on at this time, so that the driving end of the micro electric push rod 9 pushes the second bevel gear 7 and the slide column 11 to slide inward and outward of the output member 5, thereby achieving the effect of electrically adjusting the position of the second bevel gear 7, thereby avoiding the problem that the second bevel gear 7 cannot be perfectly meshed with the first bevel gear 6 due to mechanical wear such as vibration. It should be noted that during the rotation of the second bevel gear 7, the second bevel gear 7 will drive the micro electric push rod 9 to slide in the annular groove 10, thereby avoiding the problem of motion interference;

[0036] In addition, when the slide column 11 slides in the slide groove 12, the ball 14 rolls in the guide rail 13, which can change the sliding friction of the slide column 11 into rolling friction, thereby reducing friction force and friction loss.
