Description

Technical Field

[0001] The invention relates to the technical field of reducers, and in particular to a reversible multi-roller reducer. Background Art

[0002] A reversible reducer is a mechanical device that can achieve bidirectional rotation and provide different speed ratios. It is mainly used in transmission systems to control the speed and direction of the output shaft by changing the speed and direction of the input shaft. Reversible reducers are widely used in various industrial fields, such as machinery manufacturing, automation equipment, transportation equipment, etc.

[0003] The emergence of reversible reducers has solved many problems of traditional reducers. Through special structural design, the reducer can easily realize bidirectional transmission while realizing the deceleration function. The main advantages include: Bidirectional transmission: The reversible reducer can realize bidirectional transmission between the input shaft and the output shaft without additional mechanical devices, which simplifies the system design. Efficient and stable: Due to its optimized structural design, the reversible reducer can maintain efficient and stable transmission during the reversing process, reducing transmission interruption and impact.

[0004] In specific applications, when the direction of the output shaft changes, such as when it originally rotates counterclockwise to clockwise, the shaft in the reducer will continue to rotate for a period of time due to rotational inertia.

[0016] In summary, the present invention mainly has the following beneficial effects: By setting an input shaft, the input power can be connected to the input shaft. The rotation of the input shaft can make the connecting shaft rotate through the connecting component, and transmit the power to the output shaft through the reduction mechanism. When applied, the input shaft will rotate first. When the input shaft rotates initially, the restriction of the connecting shaft by the clamping part can be cancelled. When the input shaft rotates to a preset number of circles, the connecting shaft can be driven to rotate to transmit the power to the output shaft. When the restriction of the connecting shaft by the clamping part is cancelled, the problem of power loss caused by the restriction of the connecting shaft by the clamping part is avoided. When the restriction of the connecting shaft by the clamping part is cancelled, the drain port can be opened and the cone plug can be moved, and the conveying component on the bottom box can be opened to output the output shaft. The delivery component can deliver the lubricating liquid in the bottom box to the top box. The lubricating liquid in the top box can drip onto the speed reduction mechanism through the dripping tube to lubricate the speed reduction mechanism. The cone plug moves close to the dripping tube and can be plugged into the dripping tube using the top of the cone plug to reduce the flow of the lubricating liquid. When changing the rotation direction of the output shaft, the operator can stop the power source and no longer provide power to the input shaft. At this time, the multiple rollers of the speed reduction mechanism and the gear mechanisms thereon gradually reduce the rotation speed, and the connecting shaft connected to the speed reduction mechanism gradually reduces the rotation speed. When the input shaft no longer receives power, the clamping part can be reset and contact the connecting shaft again. The clamping part and the connecting shaft are connected. The friction force of the connecting shaft can be used to limit the rotation of the connecting shaft, which can accelerate the stopping effect of the connecting shaft. At the same time, because the reduction mechanism is still rotating due to the rotational inertia to provide power to the output shaft, the restriction of the clamping part alone is not enough to quickly stop the rotation of the connecting shaft. Therefore, when the clamping part contacts the connecting shaft again and generates friction between the connecting shaft, the provided cone plug can be reset and move away from the drip tube, which can increase the flow rate of the lubricating liquid, and the conveying component continues to work. The provided drain port is closed, that is, the lubricating liquid enters the reduction box through the drip tube and no longer flows into the bottom box. The liquid in the bottom box is continuously transported to the top box, so that all the lubricating liquid can flow into the reduction box and soak The reduction mechanism in the bubble reduction box uses the viscosity of lubricating grease to provide damping for the rotation of the reduction mechanism due to inertia, and cooperates with the clamping part to quickly stop the reduction mechanism, the connecting shaft and the output shaft, so as to facilitate the subsequent reverse rotation of the power source input shaft, and reverse the output shaft through the reduction mechanism. This solves the problem in the prior art that when the direction of the output shaft changes, such as when it originally rotates counterclockwise and changes to clockwise, the shaft in the reducer will continue to rotate for a period of time due to rotational inertia and cannot be stopped quickly. Before it stops, it is forced to rotate counterclockwise, and more parts cooperate with each other, which will cause greater damage to it. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0020] refer to Figure 1-Figure 7 , a reversible multi-roller reducer, comprising: Reduction box body 100; An input shaft 101 and an output shaft 102 are provided at both ends of the reduction gearbox body 100, and a reduction mechanism 103 is provided between the input shaft 101 and the output shaft 102; The connecting pipes 104 provided at both ends of the reduction gearbox 100 are respectively sleeved on the input shaft 101 and the output shaft 102; A connecting shaft 105 provided at one end of the input shaft 101, one end of which is connected to the speed reduction mechanism 103, and the other end of which is connected to the input shaft 101; A top case 106 is disposed on the top of the reduction gearbox 100, and a bottom case 107 connected to the top case 106 is connected to the bottom of the reduction gearbox 100; A plurality of drip tubes 108 are disposed on the top box body 106, and a plurality of cone plugs 109 are disposed at the bottom of the drip tubes 108; A plurality of drain ports 110 are provided on the bottom housing 107 and are connected to the reduction housing 100; A clamping portion provided in one of the connecting tubes 104, for limiting the rotation of the connecting shaft 105; The connecting component provided between the input shaft 101 and the connecting shaft 105 is used to drive the connecting shaft 105 to rotate when the input shaft 101 rotates a preset number of times. When the input shaft 101 rotates, the restriction of the clamping part on the connecting shaft 105 can be removed before the connecting shaft 105 is driven to rotate. Wherein, when the clamping part removes the restriction on the connecting shaft 105, the liquid discharge port 110 can be opened, and the cone plug 109 can move close to the drip tube 108; The conveying component provided on the bottom box 107 is used to convey the lubricating liquid in the bottom box 107 to the top box 106; By setting the input shaft 101, the input power can be connected to the input shaft 101. The rotation of the input shaft 101 can make the connecting shaft 105 rotate through the connecting component, and transmit the power to the output shaft 102 through the speed reduction mechanism 103. When used, the input shaft 101 will rotate first. When the input shaft 101 rotates initially, the restriction of the clamping part on the connecting shaft 105 can be cancelled. When the input shaft 101 rotates to a preset number of circles, the connecting shaft 105 can be driven to rotate to transmit the power to the output shaft 102. When the clamping part cancels the restriction on the connecting shaft 105, the problem of power loss caused by the restriction on the connecting shaft 105 by the clamping part is avoided. When the clamping part cancels the restriction on the connecting shaft 105, the drain port 110 can be opened to allow the cone plug 109 to move. The conveying component on the bottom box 107 is opened, and the conveying component can convey the lubricating liquid in the bottom box 107 to the top box 106. The lubricating liquid in the top box 106 can drip onto the reduction mechanism 103 through the dripping tube 108, and the reduction mechanism 103 can be lubricated. The cone plug 109 moves close to the dripping tube 108 and can be plugged into the dripping tube 108 with the top of the cone plug 109 to reduce the flow of the lubricating liquid. When changing the rotation direction of the output shaft 102, the operator can stop the power source and no longer provide power to the input shaft 101. At this time, the multiple rollers of the reduction mechanism 103 and the gear mechanism thereon gradually reduce the rotation speed, and the connecting shaft 105 connected to the reduction mechanism 103 gradually reduces the rotation speed. When the input shaft 101 is no longer receiving power When the force is applied, the clamping portion can be reset and contact the connecting shaft 105 again. The friction between the clamping portion and the connecting shaft 105 can limit the rotation of the connecting shaft 105, which can accelerate the stopping effect of the connecting shaft 105. At the same time, because the reduction mechanism 103 is still rotating to provide power to the output shaft 102 due to rotational inertia, the restriction of the clamping portion alone is not enough to quickly stop the rotation of the connecting shaft 105. For this reason, when the clamping portion contacts the connecting shaft 105 again and generates friction between the connecting shaft 105, the cone plug 109 can be reset and move away from the drip tube 108, which can increase the flow rate of the lubricating liquid, and the conveying component continues to work, and the drain port 110 is closed, that is, the lubricating liquid enters the reduction box body 100 through the drip tube 108 and no longer flows into the bottom box body. 107, the liquid in the bottom box 107 is continuously transported to the top box 106, so that all the lubricating liquid can flow into the reduction box 100 and soak the reduction mechanism 103 in the reduction box 100. The viscosity of the lubricating grease provides damping for the rotation of the reduction mechanism 103 due to inertia, and the clamping part can quickly stop the reduction mechanism 103, the connecting shaft 105 and the output shaft 102, so as to facilitate the subsequent reverse rotation of the input shaft 101 by the power source, and reverse rotation of the output shaft 102 through the reduction mechanism 103, which solves the problem in the prior art that when the direction of the output shaft 102 changes, such as when it originally rotates counterclockwise and changes to clockwise, due to rotation inertia, the shaft in the reducer will continue to rotate for a period of time and cannot be stopped quickly.If it is forced to rotate counterclockwise before it stops, the parts will be more likely to be damaged.

[0021] As a further solution of the present invention, the connecting component includes a bearing 200 arranged in the connecting tube 104, the connecting shaft 105 is connected to the inner ring of the bearing 200, a slide groove 201 is opened at one end of the output shaft 102, a slide rod 202 is slidably connected in the slide groove 201, and one end of the slide rod 202 is connected to a screw 203 threadedly connected to the connecting shaft 105; By setting the slide bar 202, when the input shaft 101 rotates, the slide bar 202 will be driven to rotate through the slide groove 201. The rotation of the slide bar 202 can drive the screw 203 to rotate. The rotation of the screw 203 can generate a translational motion in the connecting shaft 105 through the force of the thread. When the input shaft 101 rotates a preset number of circles, the screw 203 can be moved to the extreme position in the connecting shaft 105. At this time, the connecting shaft 105 can be driven to rotate by the screw 203. When the input shaft 101 rotates in the opposite direction, the screw 203 gradually moves away from the connecting shaft 105. After the slide bar 202 moves to the extreme position in the slide groove 201, the rotation of the input shaft 101 can allow the connecting shaft 105 to rotate through the slide bar 202 and the screw 203. The set bearing 200 can support the position of the connecting shaft 105 to ensure that the connecting shaft 105 does not generate a translational motion.

[0022] As a further solution of the present invention, the clamping part includes a bracket 204 connected to the connecting tube 104, two damping blocks 205 in contact with the connecting shaft 105 are arranged in the bracket 204, a first rod 206 is rotatably connected to the bracket 204, a second rod 207 rotatably connected to the damping block 205 is slidably connected to the first rod 206, and a first spring 208 is connected between the damping block 205 and the bracket 204; By setting the first rod 206 and the second rod 207, the first rod 206 and the second rod 207 can support the position of the damping block 205, and the set first spring 208 can provide the damping block 205 with a force to squeeze the connecting shaft 105, so as to achieve the purpose of providing a certain limiting force for the rotation of the connecting shaft 105.

[0023] As a further solution of the present invention, the connecting component further includes a first gear 209 connected to the input shaft 101, a receiving groove 210 is provided on the bracket 204, a reel 214 is provided in the receiving groove 210, a first traction rope 211 is connected to the reel 214, one end of the first traction rope 211 is connected to the damping block 205, a connecting rod 212 is connected to the reel 214, and one end of the connecting rod 212 is connected to a second gear 213 meshing with the first gear 209; By setting the first gear 209, when the input shaft 101 rotates to move the screw 203 but before the screw 203 causes the connecting shaft 105 to rotate, the rotation of the first gear 209 can drive the second gear 213 and the connecting rod 212 to rotate, so that the winding shaft 214 rotates to wind up the first traction rope 211, so that the first traction rope 211 causes the damping block 205 to move, thereby achieving the goal of keeping the damping block 205 away from the connecting shaft 105 before it rotates, thereby avoiding the problem of affecting its rotation.

[0024] As a further solution of the present invention, the outer fixed sleeve of the connecting rod 212 is provided with a connecting ring 300 rotatably connected to the winding shaft 214, the outer wall of the connecting ring 300 is provided with a plurality of receiving grooves 301, a top rod 302 is slidably connected in the receiving groove 301, the inner wall of the winding shaft 214 is provided with a top groove 303 adapted to the top rod 302, a second spring 304 is connected between the top rod 302 and the receiving groove 301, and one end of the top rod 302 adapted to the top groove 303 is semi-spherical; By setting the push rod 302, the push rod 302 can be engaged with the top groove 303 by the force of the second spring 304. When the connecting shaft 105 rotates, the friction between the push rod 302 and the top groove 303 can be used to rotate the winding shaft 214. When the winding shaft 214 rotates to reel in the first traction rope 211, it can overcome the force of the first spring 208, so that the damping block 205 moves. When the damping block 205 moves to the extreme position, the rotation damping of the winding shaft 214 increases, and the push rod 302 continues to rotate with the connecting rod 212. The push rod 302 is driven by the top groove 303. The squeezing force can overcome the force of the second spring 304 and shrink in the receiving groove 301. When the connecting rod 212 continues to drive the connecting ring 300 to move, when the top rod 302 corresponds to the next top groove 303, the top rod 302 moves toward the top groove 303 under the force of the second spring 304. Because the connecting ring 300 is continuously rotating, that is, the top rod 302 jumps in the receiving groove 301 and always gives the winding shaft 214 a force to rotate, so as to achieve the purpose of positioning the position of the winding shaft 214, and at the same time, it can also avoid affecting the normal rotation of the input shaft 101.

[0025] As a further solution of the present invention, a plurality of connecting bars 400 are connected to the connecting shaft 105, a connecting box 401 is connected to the connecting bar 400, and a spring spring 402 is connected between the connecting box 401 and the input shaft 101; By setting the clockwork spring 402, since the connecting shaft 105 is connected to the speed reduction mechanism 103, the rotation of the connecting shaft 105 is subject to certain restrictions in the initial state. When the input shaft 101 rotates, potential energy can be applied to the clockwork spring 402 without causing the connecting shaft 105 to rotate. The connecting shaft 105 will not rotate until the screw rod 203 moves to a preset position. When the input shaft 101 stops outputting power subsequently, the input shaft 101 loses the force to rotate, and the clockwork spring 402 can release the potential energy to cause the input shaft 101 to rotate in the opposite direction. When the input shaft 101 is subjected to the force of the clockwork spring 402 and rotates in the opposite direction, the winding shaft 214 can be caused to rotate in the opposite direction through the first gear 209, the second gear 213, the connecting rod 212, the top rod 302 and the top groove 303, so as to release the first traction rope 211 and reset the damping block 205, thereby achieving the purpose of generating rotational damping for the connecting shaft.

[0026] As a further solution of the present invention, a baffle 500 covering the discharge port 110 is provided in the bottom box 107, a connecting plate 501 is connected to the top of the bottom box 107, a blocking plate 502 is slidably connected to the connecting plate 501, a third spring 503 is connected between the blocking plate 502 and the connecting plate 501, a flow opening 504 is opened on the top of the blocking plate 502, and a support bar 505 extending into the connecting pipe 104 and connected to one of the damping blocks 205 is connected to one side of the baffle 500; By setting the support bar 505, when the damping block 205 moves, the baffle 500 can be moved through the support bar 505. The baffle 500 moves away from the drain port 110 to open the drain port 110. The liquid flowing out of the drain port 110 can enter the flow opening 504 on the baffle 500 and be guided by the flow opening 504 to enter the bottom box body 107. The liquid can be transported to the top box body 106 by the transport component.

[0027] As a further solution of the present invention, the conveying component includes a first screw rod 506 rotatably connected to the bottom box body 107, a first push plate 507 slidably connected to the bottom box body 107 is threadedly connected to the first screw rod 506, a second push plate 508 is slidably connected to the first push plate 507, a fourth spring 509 is connected between the second push plate 508 and the first push plate 507, a motor 510 connected to the first screw rod 506 is connected to the bottom box body 107, a conveying pipe 511 is connected between the bottom box body 107 and the top box body 106, and a one-way port 512 is opened on one side of the first push plate 507; By setting the second push plate 508, when the baffle 500 moves downward, the blocking plate 502 and the second push plate 508 can be pressed to move to adapt to the position of the baffle 500. When in use, the motor 510 can be used to rotate the first screw rod 506, and the two first push plates 507 arranged in the bottom box body 107 can move away from each other. A one-way valve can be set in the one-way port 512. When the two first push plates 507 move away from each other, the one-way valve is closed, and the liquid in the bottom box body 107 can be pushed into the delivery pipe 511 and enter the top box body 106 through the delivery pipe 511. When the two first push plates 507 move towards each other, the one-way valve is opened, and the liquid flowing between the two push plates can flow out from the one-way port 512, so that the liquid can enter the delivery pipe 511 when the first push plate 507 moves again next time.

[0028] As a further solution of the present invention, a frame 600 is connected inside the drip tube 108, a second screw rod 601 is rotatably connected to the frame 600, a connecting frame 602 is connected to the drip tube 108, a cone plug 109 is slidably connected to the connecting frame 602, the cone plug 109 is threadedly connected to the second screw rod 601, and a fifth spring 603 is connected between the second screw rod 601 and the connecting frame 602; By setting the second screw rod 601, when the damping block 205 moves away from the connecting shaft 105, the second screw rod 601 can be rotated, and the rotation of the second screw rod 601 allows the cone plug 109 to move through the force of the thread. The cone plug 109 moves close to the drip tube 108 to achieve the purpose of reducing the liquid flow rate, thereby avoiding the normal operation of the speed reduction mechanism 103 affected by excessive flow of lubricating grease.

When the damping block 205 moves away from the connecting shaft 105, the sixth spring releases the potential energy, so that the second screw rod 601 can rotate and reel in the second traction rope 606. The rotation of the second screw rod 601 can move the cone plug 109 through the force of the thread. When the damping block 205 moves toward the connecting shaft 105, the second traction rope 606 can be pulled, and the cone plug 109 is reset downward, which can increase the flow rate of the liquid.
