Description

Technical Field

[0001] The present invention belongs to the technical field of dryer equipment, and in particular relates to an anti-impact connection device and a self-compensation method for a dryer reducer. Background Art

[0002] Double-cone dryers are widely used in the chemical, food, and pharmaceutical industries due to their efficient mixing and drying capabilities. However, the double-cone dryer's cylinder itself is heavy, resulting in significant impact during rotation. This is especially true when the dryer is stopped. The impact load generated by the cylinder's inertia is transmitted to the reducer, causing significant load and damage.

[0003] Conventional double cone dryers (such as Figure 1 ), a driving sprocket, a driven sprocket and a chain are usually used for transmission between the double-cone cylinder and the reducer, which not only makes the reducer bear torque, but also radial tension. The impact load generated by the inertia of the double-cone cylinder will cause the reducer casing to rupture, thereby causing damage to the dryer and high maintenance costs. Summary of the Invention

[0004] The purpose of the present invention is to address the above-mentioned technical problems and provide an impact-resistant connection device and a self-compensation method for a dryer reducer, thereby reducing the damage to the reducer caused by the inertial impact of the double-cone cylinder and reducing the maintenance cost of equipment damaged by inertial impact.

[0005] In view of this, the present invention provides a dryer reducer anti-impact connection device, comprising: A double-cone cylinder with a rotating shaft on the side and a driven gear on the rotating shaft; The shell is mounted on the side of the double-cone cylinder, and the shaft extends to the top of the shell and is rotatably connected via a bearing; The reducer is fixedly installed in the housing, and its output shaft is coaxially connected to the transmission shaft through a coupling; A bearing seat is fixedly installed in the housing and supports the transmission shaft, and the transmission shaft is provided with a driving gear meshing with the driven gear; Among them, the bearing seat is used to withstand the inertial impact load transmitted to the transmission shaft when the double-cone cylinder rotates.

[0006] In the above technical solution, further: There are two bearing seats, which are symmetrically arranged on both sides of the axial direction of the driving gear to evenly support the transmission shaft and withstand the inertial impact load when the double-cone cylinder rotates.

[0007] In the above technical solution, further: A bracket for fixing the bearing seat is provided in the housing.

[0008] In the above technical solution, further, the coupling includes: The first connecting end is sleeved on the output shaft; The second connecting end is sleeved on an end of the transmission shaft close to the reducer and connected to the first connecting end; A compensation structure is installed between the first connecting end and the second connecting end, and is used for torque transmission linkage between the transmission shaft and the output shaft, and allows relative rotation within a preset angular range in the opposite direction of torque transmission; The first connecting end is key-connected to the output shaft, and the second connecting end is rotationally connected to the transmission shaft.

[0009] In the above technical solution, further: The preset angle range is 0°-40°.

[0010] In the above technical solution, further, the compensation structure includes: The guide ring is mounted on the transmission shaft and is used for torque transmission linkage and can be axially offset along the transmission shaft; A connecting member is installed between the guide ring and the first connecting end, and is used for abutting when torque is transmitted between the two, and for pushing the guide ring to deflect axially when relative rotation occurs in the opposite direction of torque transmission; The reset member is installed at the second connection end and is used for resetting the guide ring after axial deviation occurs and for limiting the maximum axial deviation of the guide ring.

[0011] In the above technical solution, further: The connecting member includes a ball, and the first connecting end and the opposite surface of the guide ring are respectively provided with a first guide slope and a second guide slope in opposite directions; Among them, the first guide slope and the second guide slope both include a slope surface, a pushing surface and an arc-shaped guide surface, and when the output shaft and the transmission shaft are linked for torque transmission, the ball abuts against both pushing surfaces. When the output shaft and the transmission shaft rotate relative to each other, the ball rolls on the slope surface along the arc-shaped guide surface and pushes the guide ring to axially offset.

[0012] In the above technical solution, further: The reset member includes an elastic washer, and the second connecting end is provided with a stepped groove for mounting the elastic washer and the guide ring; The elastic washer is used to elastically buffer the guide ring when it undergoes axial displacement, and the stepped groove is used to limit the maximum axial displacement distance of the guide ring.

[0013] In the above technical solution, further: A wear-resistant gasket is provided on a side of the elastic washer close to the guide ring.

[0014] The present invention provides a self-compensation method for a dryer reducer anti-impact connection device, comprising the following steps: S1: The reducer starts and drives the double cone cylinder to rotate through the output shaft, the first connecting end, the ball, the guide ring, the transmission shaft, the driving gear, the driven gear and the rotating shaft in sequence; S2: When the reducer stops, the first connection end stops, and the guide ring continues to rotate relative to the first connection end due to the inertial impact of the double-cone cylinder to perform rotation compensation; S3: The first guide slope and the second guide slope rotate relative to each other, driving the ball to move along the arc-shaped guide surface on the slope, and pushing the guide ring to axially displace; S4: The guide ring moves axially and squeezes the reset member to buffer the inertial impact and reduce the transmission of the inertial impact to the output shaft; S5: When the reducer is started again, the first guide slope and the second guide slope rotate relative to each other, causing the two pushing surfaces to continue to abut against the balls, and the guide ring is reset under the action of the reset member.

[0015] The beneficial effects of the present invention are: 1. A transmission shaft is set between the double-cone cylinder and the reducer for transmission, and the transmission shaft is installed and fixed by a bearing seat. The traditional chain transmission is eliminated, so that the driving gear and the driven gear are directly engaged. While weakening the radial tension, the bearing seat is used to absorb the radial impact, effectively reducing the inertial impact load of the double-cone cylinder from being transmitted to the reducer, avoiding damage to the reducer and reducing the maintenance cost of impact damage caused by the excessive weight of the double-cone cylinder of the dryer.

[0016] 2. By providing two bearing seats and providing a bracket to install and fix the bearing seats, the structural strength and stability of the bearing seats are improved, which can better cope with inertial impact loads.

[0017] 3. Through the compensation structure, the transmission shaft can compensate for the rotation angle when it is subjected to torque load, and the reset part can buffer and absorb the inertial impact load, which can effectively reduce the transmission of torque load to the reducer, further reduce damage to the reducer, and avoid high maintenance costs.

[0019] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0020] Example 1: This embodiment provides an anti-impact connection device for a dryer reducer, comprising: A double-cone cylinder 1 is provided with a rotating shaft 2 on the side thereof, and a driven gear 3 is provided on the rotating shaft 2; The housing 4 is mounted on the side of the double-cone cylinder 1, and the rotating shaft 2 extends to the top of the housing 4 and is rotatably connected via a bearing; The reducer 5 is fixedly installed in the housing 4, and its output shaft is coaxially connected to the transmission shaft 7 through a coupling 6; The bearing seat 8 is fixedly mounted in the housing 4 and supports the transmission shaft 7, and the transmission shaft 7 is provided with a driving gear 9 meshing with the driven gear 3; The bearing seat 8 is used to bear the inertial impact load transmitted to the transmission shaft 7 when the double-cone cylinder 1 rotates; At the same time, the dryer, specifically the other mechanisms of the double-cone dryer, and the specific structures of the reducer 5 and the bearing seat 8 are existing mature technologies, which are known to technicians in the relevant technical field from the traditional reducer 5 and the bearing seat 8 and will not be repeated here.

[0021] It can be seen from the present embodiment that by arranging a transmission shaft 7 between the double-cone cylinder 1 and the reducer 5 for transmission, and installing and fixing the transmission shaft 7 through the bearing seat 8, and canceling the chain transmission, the driving gear 9 and the driven gear 3 are directly engaged, while weakening the radial tension, the radial impact is absorbed by the bearing seat 8, effectively reducing the inertial impact load of the double-cone cylinder 1 from being transmitted to the reducer 5, avoiding damage to the reducer 5, and reducing the maintenance cost of impact damage caused by the excessive weight of the double-cone cylinder 1 of the dryer.

[0022] Example 2: This embodiment provides an anti-impact connection device for a dryer reducer, which, in addition to the technical solutions of the above embodiments, also has the following technical features: There are two bearing seats 8, which are symmetrically arranged on both sides of the axial direction of the driving gear 9 to evenly support the transmission shaft 7 and withstand the inertial impact load when the double-cone cylinder 1 rotates.

[0023] It can be seen from this embodiment that by providing two bearing seats 8 and symmetrically arranging them on both axial sides of the driving gear 9, the structural stability can be improved and the stability in bearing inertial impact loads can be improved.

[0024] Example 3: This embodiment provides an anti-impact connection device for a dryer reducer, which, in addition to the technical solutions of the above embodiments, also has the following technical features: A bracket 10 for fixing the bearing seat 8 is provided in the housing 4; The bracket 10 is installed and connected in a detachable manner, specifically by bolt connection and fixation.

[0025] It can be seen from this embodiment that by providing a bracket 10 to install and fix the bearing seat 8, the structural strength and stability of the installation of the bearing seat 8 are improved, and the inertial impact load can be better coped with.

[0026] Example 4: This embodiment provides an anti-impact connection device for a dryer reducer. In addition to the technical solutions of the above embodiments, it also has the following technical features: the coupling 6 includes: The first connecting end 60 is sleeved on the output shaft; The second connecting end 61 is sleeved on the end of the transmission shaft 7 close to the reducer 5 and connected to the first connecting end 60; The compensation structure is installed between the first connecting end 60 and the second connecting end 61 and is used for torque transmission linkage between the transmission shaft 7 and the output shaft, and allows relative rotation within a preset angular range in the opposite direction of torque transmission; The first connecting end 60 is key-connected to the output shaft, while the second connecting end 61 is rotationally connected to the transmission shaft 7; At the same time, the key connection between the first connecting end 60 and the output shaft can be a spline or a flat key connection, the second connecting end 61 and the transmission shaft 7 can be a clearance fit, and the first connecting end 60 and the second connecting end 61 can be connected by flange end faces and installed by bolts; Furthermore, in addition to the preset angle range in the opposite direction of torque transmission, an additional safety angle should also be provided.

[0027] It can be seen from this embodiment that a compensation structure is provided in the coupling 6 between the transmission shaft 7 and the output shaft of the reducer 5, so that the transmission shaft 7 and the output shaft can be linked to perform torque transmission in the driving direction, and relative rotation can be allowed in the opposite direction of torque transmission. After the reducer 5 stops, the transmission shaft 7 can undergo compensatory rotation under the inertial impact load of the double-conical cylinder 1, thereby avoiding the torque force under the action of inertia acting on the output shaft, thereby avoiding impact and damage to the reducer 5.

[0028] Example 5: This embodiment provides an anti-impact connection device for a dryer reducer, which, in addition to the technical solutions of the above embodiments, also has the following technical features: The preset angle range is 0°-40°; The preset angle range can also be different. Specifically, it can be determined according to the specific dead weight of the double-cone cylinder 1 of the double-cone dryer. If the dead weight is large, the preset angle range can be increased, while if the dead weight is small, the preset angle range can be reduced.

[0029] It can be seen from this embodiment that the preset angle range of relative rotation between the transmission shaft 7 and the output shaft is adaptively set based on the specific weight of the double-conical cylinder 1, which can minimize the inertial impact load transmitted to the output shaft, so that the inertial impact load of the double-conical cylinder 1 gradually dissipates under the action of resistance such as friction.

[0030] Example 6: This embodiment provides an anti-impact connection device for a dryer reducer. In addition to the technical solutions of the above embodiments, it also has the following technical features. The compensation structure includes: The guide ring 62 is sleeved on the transmission shaft 7 and is used for torque transmission linkage and can be axially offset along the transmission shaft 7; The connecting member 63 is installed between the guide ring 62 and the first connecting end 60 and is used for abutting when the torque is transmitted between the two, and for pushing the guide ring 62 to deflect axially when relative rotation occurs in the opposite direction of the torque transmission; The reset member 64 is installed at the second connecting end 61 and is used to reset the guide ring 62 after axial deviation occurs and to limit the maximum axial deviation of the guide ring 62; Among them, the guide ring 62 is made of metal, and the guide ring 62 and the transmission shaft 7 can be connected by a key, specifically, a spline or a flat key connection, which can be selected according to needs and will not be repeated here.

[0031] It can be seen from this embodiment that the connecting member 63 is used to abut the guide ring 62 and the first connecting end 60 during torque transmission, so that the torque of the output shaft is transmitted to the transmission shaft 7 through the first connecting end 60, the connecting member 63 and the guide ring 62 in sequence, thereby ensuring the transmission of torque. In the opposite direction of torque transmission, when the transmission shaft 7 and the output shaft valve core rotate relative to each other, the guide ring 62 can be pushed to deflect axially, thereby compressing the reset member 64 to buffer and absorb the inertial impact load, so that the double-cone cylinder 1 can be stabilized more quickly, that is, the inertial impact load can be eliminated more quickly. Furthermore, the reset member 64 can limit the maximum axial displacement of the guide ring 62, thereby ensuring the stability of the structure.

[0032] Example 7: This embodiment provides an anti-impact connection device for a dryer reducer, which, in addition to the technical solutions of the above embodiments, also has the following technical features: The connecting member 63 includes a ball 630, and the first connecting end 60 and the guide ring 62 have oppositely directed first and second guide slopes 631 and 632, respectively. The first guide slope 631 and the second guide slope 632 each include a slope surface 6310, a push surface 6311, and an arcuate guide surface 6312. When the output shaft and the transmission shaft 7 are in torque transmission linkage, the ball 630 abuts against both push surfaces 6311. When the output shaft and the transmission shaft 7 rotate relative to each other, the ball 630 rolls on the slope surface 6310 along the arcuate guide surface 6312, pushing the guide ring 62 axially to deflect. The ball 630 is made of metal. At the same time, by adopting the setting of the ball 630 and the first guide slope 631 and the second guide slope 632, the benefit of reducing the preset angle range can increase the number of settings of the ball 630 and the first guide slope 631 and the second guide slope 632 in the circumferential direction, specifically 360° / (maximum value of the preset angle range + additional safety angle) = N, N is the number of settings of the ball 630 and the first guide slope 631 and the second guide slope 632, and N is a positive integer and is greater than or equal to 2. Taking the present application as an example, N is 8, and the maximum value of the preset angle range is 40°, and the additional safety angle is 5°.

[0033] As can be seen from this embodiment, by using the ball 630, the first guide slope 631, and the second guide slope 632 in the connecting member 63, when the guide ring 62 approaches the first connecting end 60, the ball 630 is located on the side of the first guide slope 631 and the second guide slope 632 close to the pushing surface 6311, that is, the ball 630 is embedded in the first guide slope 631 and the second guide slope 632. Because the first guide slope 631 and the second guide slope 632 are opened in opposite directions, the two pushing surfaces 6311 respectively abut against the two side surfaces of the ball 630, and then the first connecting end 60 pushes the ball 630 through the pushing surface 6311 of the first guide slope 631, and the ball 630 pushes the guide ring 62 to rotate through the pushing surface 6311 of the second guide slope 632, thereby rotating the transmission shaft 7, thereby ensuring the transmission of torque; The first guide slope 631 and the second guide slope 632 also include a slope surface 6310 and an arc-shaped guide surface 6312, so that after the reducer 5 stops, that is, the first connecting end 60 stops rotating, the guide ring 62 will continue to rotate due to the inertial impact load of the double-cone cylinder 1, and prompt the two pushing surfaces 6311 to leave the ball 630. The ball 630 moves along the slope surface 6310 and pushes the guide ring 62 axially to compress the reset member 64. The elastic force of the reset member 64 offsets the inertial impact load to prevent the inertial impact load from being transmitted to the output end and causing damage to the reducer 5.

[0034] Example 8: This embodiment provides an anti-impact connection device for a dryer reducer, which, in addition to the technical solutions of the above embodiments, also has the following technical features: The reset member 64 includes an elastic washer 640 , and the second connecting end 61 is provided with a stepped groove 610 for mounting the elastic washer 640 and the guide ring 62 ; The elastic washer 640 is used to elastically buffer the guide ring 62 when it deviates axially, and the stepped groove 610 is used to limit the maximum axial deviation distance of the guide ring 62; Meanwhile, the elastic washer 640 is made of rubber, and the inner wall diameter of the stepped groove 610 for installing the elastic washer 640 is smaller than the inner wall diameter for installing the guide ring 62 .

[0035] As can be seen from this embodiment, by using the elastic washer 640 for the reset member 64, the buffering process can be made smoother and rebound can be reduced, thereby improving stability and buffering effect. In addition, the provision of the stepped groove 610 improves the installation stability of the reset member 64 and the guide ring 62. Furthermore, the elastic washer 640 is used so that, after being squeezed by the guide ring 62, its radial dimension increases, so that the surface of the elastic washer 640 on the side close to the axis abuts against the surface of the transmission shaft 7, thereby increasing the friction force and the frictional resistance to the rotation of the transmission shaft 7, so that the swing of the double-cone cylinder 1 caused by inertia and gravity can be stabilized more quickly. The setting of the stepped groove 610 can limit the maximum axial offset distance of the guide ring 62, thereby preventing the ball 630 from falling out of the first guide slope 631 and the second guide slope 632 due to a large axial offset of the guide ring 62, thereby improving the structural stability.

[0036] Example 9: This embodiment provides an anti-impact connection device for a dryer reducer, which, in addition to the technical solutions of the above embodiments, also has the following technical features: A wear-resistant gasket 641 is provided on the side of the elastic washer 640 close to the guide ring 62; The wear-resistant gasket 641 may be made of polytetrafluoroethylene.

[0037] It can be seen from this embodiment that by setting the wear-resistant gasket 641, the wear resistance between the guide ring 62 and the elastic gasket 640 is improved, friction and wear are reduced, and the service life is extended. In addition, the use of polytetrafluoroethylene material makes the guide ring 62 and the elastic gasket 640 have a lubrication effect. Although the friction resistance between the guide ring 62 and the elastic gasket 640 is reduced, it has no beneficial effect on absorbing inertial impact loads, but it can effectively extend the service life. The benefits brought by extending the service life of the elastic gasket 640 and the wear-resistant gasket 641 are far greater than the benefits brought by the friction resistance generated by direct contact between the guide ring 62 and the elastic gasket 640.

[0038] Example 10: This embodiment provides a self-compensation method for a dryer reducer anti-impact connection device, comprising the following steps: S1: The reducer 5 is started and drives the double-cone cylinder 1 to rotate through the output shaft, the first connecting end 60, the ball 630, the guide ring 62, the transmission shaft 7, the driving gear 9, the driven gear 3 and the rotating shaft 2 in sequence; S2: When the reducer 5 stops, the first connecting end 60 stops, and the guide ring 62 continues to rotate relative to the first connecting end 60 due to the inertial impact of the double-cone cylinder 1 to perform rotation compensation; S3: The first guide slope 631 and the second guide slope 632 rotate relative to each other, driving the ball 630 to move along the arc-shaped guide surface 6312 on the slope 6310 and pushing the guide ring 62 to axially displace; S4: The guide ring 62 moves axially and squeezes the reset member 64, buffering the inertial impact and reducing the inertial impact from being transmitted to the output shaft; S5: When the reducer 5 is started again, the first guide slope 631 and the second guide slope 632 rotate relative to each other, and the two pushing surfaces 6311 continue to abut against the balls 630 , and the guide ring 62 is reset under the action of the reset member 64 .

[0039] It can be seen from this embodiment that the ball 630 abuts against the pushing surface 6311 of the first guide slope 631 and the second guide slope 632, thereby enabling the torque of the output shaft to be transmitted to the transmission shaft 7, thereby driving the double-cone cylinder 1 to rotate, and after the reducer 5 stops, the transmission shaft 7 and the output shaft are rotated and offset to compensate, and the ball 630 is prompted to move along the arc-shaped guide surface 6312 on the slope 6310 to push the guide ring 62 to axially displace, thereby squeezing the reset member 64 to absorb and consume the inertial impact load, effectively preventing the inertial impact from being transmitted to the output shaft, and reducing the impact and damage to the reducer 5; And after the reducer 5 is restarted, with the rotation of the output shaft and the reset action of the reset member 64, the ball 630 again contacts the abutment surfaces of the first guide slope 631 and the second guide slope 632, and then drives the double-cone cylinder 1 to rotate through the guide ring 62, the transmission shaft 7, the driving gear 9, the driven gear 3 and the rotating shaft 2 in sequence.

[0040] The embodiments of the present application are described above in conjunction with the accompanying drawings. Unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.

A self-compensation method for the anti-impact connection device of a dryer reducer according to any one of claims 4 to 9, characterized in that: The following steps are involved: S1: The reducer (5) is started and drives the double-cone cylinder (1) to rotate through the output shaft, the first connecting end (60), the ball (630), the guide ring (62), the transmission shaft (7), the driving gear (9), the driven gear (3) and the rotating shaft (2); S2: When the reducer (5) stops, the first connecting end (60) stops, and the guide ring (62) continues to rotate relative to the first connecting end (60) due to the inertial impact of the double-cone cylinder (1), performing rotation compensation; S3: The first guide slope (631) and the second guide slope (632) rotate relative to each other, driving the ball (630) to move along the arc-shaped guide surface (6312) on the slope surface (6310), and pushing the guide ring (62) to axially displace; S4: The guide ring (62) is axially displaced and squeezes the reset member (64), thereby buffering the inertial impact and reducing the transmission of the inertial impact to the output shaft; S5: When the reducer (5) is started again, the first guide slope (631) and the second guide slope (632) rotate relative to each other, causing the two pushing surfaces (6311) to continue to abut against the ball (630), and the guide ring (62) is reset under the action of the reset member (64).
