Description

Technical Field

[0001] This invention belongs to the technical field of ring spinning machines, and specifically relates to a double-output shaft reducer for ring spinning machines. Background Technology

[0002] In traditional ring spinning machines, the drive structure used to drive the ring rail and yarn guide plate to move up and down includes a power component and a transmission component. The power component mainly includes a motor, and the transmission component mainly includes a reducer with a single output shaft design. The reducer transmits the running power provided by the motor unidirectionally to the ring rail and yarn guide plate to achieve their up and down movement.

[0003] However, as market demand for the output and production efficiency of ring spinning machines has become increasingly significant, the number of spindles in ring spinning machines has also increased. Consequently, in long and extra-long ring spinning machines, the load on the lifting system components responsible for the lifting and lowering of the ring rail and yarn guide plate has increased exponentially. In order to enable normal lifting and lowering operations, it is necessary to continuously improve the load-bearing capacity of the reducer mechanism components. However, this approach would result in a large reducer housing, which contradicts the limited space available for the reducer within the main machine head. Alternatively, two sets of unidirectional transmission reducers could be installed, but this approach would not only increase the space occupied by the equipment but also compromise the consistency of the two lifting transmission mechanisms during operation. Therefore, there is an urgent need for a reducer mechanism that can achieve stable lifting and lowering transmission while also miniaturizing the equipment. Summary of the Invention

[0004] In view of this, the present invention provides a dual-output shaft reducer for ring spinning machines, which aims to reduce the overall size of the reducer while simultaneously transmitting power from an external power source in both directions by designing the internal space of the housing and the arrangement of the power input shaft, the first intermediate shaft, the second intermediate shaft and the power output shaft within the housing.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A dual-output shaft reducer for a ring spinning frame is disposed in the middle of the ring spinning frame body for bidirectional speed reduction transmission of the power driving the ring rail and yarn guide plate to move up and down. The dual-output shaft reducer includes: a housing and a reduction system, wherein the housing supports the reduction system, wherein:

[0007] The shell is generally rectangular. The shell has a partition plate inside, which divides the internal space of the shell into a worm gear transmission cavity and a gear transmission cavity. The worm gear transmission cavity also has a fixing block with a fixing hole.

[0008] The reduction system includes a shaft system assembly and a gear transmission assembly, wherein:

[0009] The shaft system assembly includes a power input shaft located within the worm gear transmission cavity. The power input shaft extends into the worm gear transmission cavity through a bearing mounting hole pre-set on the housing and engages with a fixing hole. Furthermore, the shaft system assembly includes a first intermediate shaft and a second intermediate shaft. The first intermediate shaft passes through a partition plate, which divides the first intermediate shaft into two parts located within the worm gear transmission cavity and the gear transmission cavity, respectively. The first intermediate shaft and the power input shaft are arranged perpendicularly to each other. The second intermediate shaft is located within the gear transmission cavity and is positioned above the first intermediate shaft. In addition, the shaft system assembly includes a power output shaft. The power output shaft passes through the partition plate, the worm gear transmission cavity, and the gear transmission cavity simultaneously, with its two output ends extending to both sides of the housing.

[0010] The gear transmission assembly includes a worm gear portion on the power input shaft, a worm wheel portion and a first gear on the first intermediate shaft, a second gear on the second intermediate shaft, and a third gear on the power output shaft. Based on the meshing of the worm wheel portion and the worm gear portion, the meshing of the first gear and the second gear, and the meshing of the second gear and the third gear, the operating power transmitted by the dual-output shaft reducer to the reduction system through the power input shaft is transmitted bidirectionally from the two output ends of the power output shaft.

[0011] Preferably, on the housing, the bearing mounting hole engages with the power input shaft via a first rolling bearing, and a first through cover is provided on one side of the first rolling bearing. The power input shaft passes through the first through cover, and an oil seal is also provided on the first through cover to seal the gap between the first through cover and the power input shaft.

[0012] Preferably, in the worm gear transmission cavity inside the housing, a second rolling bearing is provided inside the fixing hole. Based on the fact that one end of the power input shaft is engaged with the fixing hole through the second rolling bearing and the other end of the power input shaft is engaged with the bearing mounting hole through the first rolling bearing, the rotation of the power input shaft in the worm gear transmission cavity is realized. In addition, the end of the power input shaft located outside the housing is connected to an external power source.

[0013] Preferably, both ends of the first intermediate shaft are engaged with the side wall of the housing via third rolling bearings, and the partition plate is also engaged with the first intermediate shaft via third rolling bearings. Based on the engagement of the three third rolling bearings with the first intermediate shaft, the rotation of the first intermediate shaft within the housing is achieved.

[0014] In addition, the outer wall of the housing is provided with a second cover at the positions corresponding to the two ends of the first intermediate shaft, and the gap between the first intermediate shaft and the housing is sealed by the second cover.

[0015] Preferably, one end of the second intermediate shaft is engaged with the side wall of the housing via a fourth rolling bearing, and the other end of the second intermediate shaft is also engaged with the partition plate via a fourth rolling bearing. Based on this, the second intermediate shaft and the power input shaft are in the same horizontal plane.

[0016] In addition, the outer wall of the housing is provided with a third cover at the position corresponding to the end of the second intermediate shaft, and the gap between the second intermediate shaft and the housing is sealed by the third cover.

[0017] Preferably, both output ends of the power output shaft are engaged with the side wall of the housing via fifth rolling bearings, and the partition plate is also engaged with the power output shaft via fifth rolling bearings. Based on the engagement of the three fifth rolling bearings with the power output shaft, the rotation of the power output shaft within the housing is achieved.

[0018] In addition, on the outer wall of the housing, each of the fifth rolling bearings is provided with a second through cover on one side. The two output ends of the power output shaft pass through the two second through covers respectively. Each second through cover is also provided with an oil seal to seal the gap between the power output shaft and the second through cover.

[0019] Preferably, the top of the housing is also provided with a top cover, and the top cover is also provided with a lifting ring and a vent plug, which are used to lift the dual-output shaft reducer and to discharge the air inside the dual-output shaft reducer, respectively. The bottom of the housing is also provided with a mounting plate, and the mounting plate is provided with a plurality of first mounting holes. The housing is mounted on the ring spinning machine body by means of the cooperation of the first mounting holes and fixing bolts.

[0020] Preferably, the housing is further provided with an oil hole, which is located below the bearing mounting hole, and a first cap is also provided on the oil hole to seal the oil hole.

[0021] Preferably, the side wall of the housing is further provided with a vernier mounting hole, and the vernier mounting hole is located on one side of the power output shaft. The vernier mounting hole is used to install a vernier.

[0022] The beneficial effects of this invention are as follows:

[0023] In general, this invention incorporates a partition plate within the housing to divide the internal space. The arrangement of the power input shaft, first intermediate shaft, second intermediate shaft, and power output shaft within the housing is designed to minimize the size of the dual-output shaft reducer. Furthermore, the invention configures the two output ends of the power output shaft to extend outside the housing and be located on both sides of the housing. This allows the reducer to transmit power to both sides of the dual-output shaft reducer, enabling it to simultaneously drive two sets of lifting transmission mechanisms for the ring rail and yarn guide plate in both directions. This avoids the problem of the reducer's size increasing exponentially due to the need to improve load-bearing capacity. It also solves the potential problem of inconsistent lifting actions between the two lifting transmission mechanisms when two unidirectional reducers transmit power to them separately. This provides technical support for the development of ultra-large spindle-count extra-long spinning frames. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0030] The dual-output shaft reducer provided in this application is located in the middle of the ring spinning frame body and is used to transmit the power for bidirectional speed reduction of the lifting and lowering motion of the ring rail and the yarn guide plate. It should be noted that the ring rail and the yarn guide plate are the moving mechanisms in the ring spinning frame, and they mainly rely on a separate power system to provide the power for their lifting and lowering motion. Considering the characteristic that the load-bearing capacity of the lifting system components in long and extra-long machines is positively correlated with their own volume, the transmission components driving the lifting system are designed bidirectionally, thus resulting in the dual-output shaft reducer of this application.

[0031] Specifically in this technical solution, such as Figure 1-2 As shown, the dual-output shaft reducer includes: a housing 1 and a reduction system. The housing 1 is used to support the reduction system, wherein:

[0032] The shell 1 is generally rectangular. The interior of the shell 1 is provided with a partition plate 101, which divides the interior space of the shell 1 into a worm gear transmission cavity 2 and a gear transmission cavity 3. The worm gear transmission cavity 2 is also provided with a fixing block 102, and the fixing block 102 is provided with a fixing hole 103.

[0033] like Figure 3 As shown, the reduction system includes a shaft assembly 4 and a gear transmission assembly 5, wherein:

[0034] The shaft assembly 4 includes a power input shaft 401 located in the worm gear transmission cavity 2. The power input shaft 401 extends into the worm gear transmission cavity 2 through a bearing mounting hole 104 pre-set on the housing 1 and then engages with a fixing hole 103.

[0035] More specifically, the bearing mounting hole 104 is engaged with the power input shaft 401 through the first rolling bearing 105; the fixed hole 103 is provided with a second rolling bearing 106. Based on the fact that one end of the power input shaft 401 is engaged with the fixed hole 103 through the second rolling bearing 106 and the other end of the power input shaft 401 is engaged with the bearing mounting hole 104 through the first rolling bearing 105, the rotation of the power input shaft 401 in the worm gear transmission cavity 2 is realized. In addition, the end of the power input shaft 401 located outside the housing 1 is connected to an external power source to transmit the running power provided by the external power source to the reduction system.

[0036] like Figure 3 As shown, the shaft assembly 4 also includes a first intermediate shaft 402 and a second intermediate shaft 403. The first intermediate shaft 402 passes through the partition plate 101 and is divided into two parts located in the worm gear transmission cavity 2 and the gear transmission cavity 3, respectively. The first intermediate shaft 402 and the power input shaft 401 are arranged perpendicular to each other. In addition, both ends of the first intermediate shaft 402 are engaged with the side wall of the housing 1 through the third rolling bearing 107. The partition plate 101 and the first intermediate shaft 402 are also engaged with the third rolling bearing 107. Based on the engagement of the three third rolling bearings 107 with the first intermediate shaft 402, the rotation of the first intermediate shaft 402 within the housing 1 is realized.

[0037] The second intermediate shaft 403 is disposed in the gear transmission cavity 3 and is located above the first intermediate shaft 402. The second intermediate shaft 403 and the power input shaft 401 are in the same horizontal plane. One end of the second intermediate shaft 403 is engaged with the side wall of the housing 1 through the fourth rolling bearing 108, and the other end of the second intermediate shaft 403 is also engaged with the partition plate 101 through the fourth rolling bearing 108.

[0038] Based on the above embodiments, with the power input shaft 401, the first intermediate shaft 402 and the second intermediate shaft 403 respectively installed inside the housing 1, the second intermediate shaft 403 is positioned above the first intermediate shaft 402, and the second intermediate shaft 403 and the power input shaft 401 are in the same horizontal plane. The first intermediate shaft 402 and the power input shaft 401 are arranged perpendicular to each other. This results in a compact arrangement structure between the power input shaft 401, the first intermediate shaft 402 and the second intermediate shaft 403, which helps to reduce the overall volume of the dual-output shaft reducer and make it miniaturized.

[0039] Based on this, such as Figure 3As shown, the shaft assembly 4 also includes a power output shaft 404. The power output shaft 404 passes through the partition plate 101, the worm gear transmission cavity 2 and the gear transmission cavity 3. The two output ends of the power output shaft 404 extend to both sides of the housing 1. Both output ends of the power output shaft 404 are engaged with the side wall of the housing 1 through the fifth rolling bearing 109. The partition plate 101 and the power output shaft 404 are also engaged through the fifth rolling bearing 109. Based on the engagement of the three fifth rolling bearings 109 and the power output shaft 404, the rotation of the power output shaft 404 within the housing 1 is realized.

[0040] At this point, the arrangement of the shaft system assembly 4 in the dual-output shaft reducer is complete. Based on this, the power transmission in the reducer also requires the arrangement of gears between the shafts. Specifically, a gear transmission assembly 5 is also set based on the shaft system assembly 4.

[0041] like Figure 3 As shown, the gear transmission assembly 5 includes a worm gear portion 501 on the power input shaft 401, a worm wheel portion 502 and a first gear 503 on the first intermediate shaft 402, a second gear 504 on the second intermediate shaft 403, and a third gear 505 on the power output shaft 404. Based on the meshing of the worm wheel portion 502 and the worm gear portion 501, the meshing of the first gear 503 and the second gear 504, and the meshing of the second gear 504 and the third gear 505, the operating power transmitted by the dual-output shaft reducer to the reduction system through the power input shaft 401 is transmitted bidirectionally from the two output ends of the power output shaft 404.

[0042] It should be noted here that the reduction ratio in the reducer is determined by factors such as the number of teeth between the gears. In this application, the reduction ratio of the double-output shaft reducer for the ring spinning machine can be obtained according to the actual needs based on conventional design methods in the prior art, and the number of teeth and other parameters of each gear can be calculated from there. This application only improves and explains the transmission method of the lifting system in the ring spinning machine, that is, the bidirectional transmission form, and does not limit the specific reduction ratio and other parameters.

[0043] In addition, this application also considers the sealing performance of the dual-output shaft reducer during normal operation, specifically, as follows: Figure 1As shown, this application also provides a first through cover 110 on one side of the first rolling bearing 105, through which the power input shaft 401 passes. An oil seal is also fitted on the first through cover 110 to seal the gap between the first through cover 110 and the power input shaft 401. The outer wall of the housing 1 also provides a second cover 111 at positions corresponding to the two ends of the first intermediate shaft 402, sealing the gap between the first intermediate shaft 402 and the housing 1. The outer wall of the housing 1 also provides a third cover 112 at positions corresponding to the ends of the second intermediate shaft 403, sealing the gap between the second intermediate shaft 403 and the housing 1. On the outer wall of the housing 1, a second through cover 113 is provided on one side of each fifth rolling bearing 109. The two output ends of the power output shaft 404 pass through two second through covers 113 respectively, and an oil seal is also fitted on each second through cover 113 to seal the gap between the power output shaft 404 and the second through cover 113.

[0044] In this technical solution, such as Figure 1 As shown, the top of the housing 1 is also provided with a top cover 114, and the top cover 114 is also provided with a lifting ring 119 and a vent plug 120, which are used to lift the dual-output shaft reducer and to vent the air inside the dual-output shaft reducer, respectively. The bottom of the housing 1 is also provided with a mounting plate 115, which is provided with several first mounting holes 116. The housing 1 is mounted on the ring spinning machine body through the cooperation of the first mounting holes 116 and the fixing bolts. The housing 1 is also provided with an oil hole, which is located below the bearing mounting hole 104. The oil hole is also provided with a first cap 117 for sealing the oil hole. The side wall of the housing 1 is also provided with a vernier mounting hole, which is located on one side of the power output shaft 404. The vernier mounting hole is used to install a vernier 118.

[0045] In general, the dual-output shaft reducer provided by this invention is applied in long or extra-long ring spinning machines. The dual-output shaft reducer has a partition plate 101 in the housing 1. Based on the partition plate 101 dividing the internal space of the housing 1, the arrangement of the power input shaft 401, the first intermediate shaft 402, the second intermediate shaft 403, and the power output shaft 404 within the housing 1 is designed to make the reducer body more compact. Furthermore, this invention also configures the two output ends of the power output shaft 404 to extend to the outside of the housing 1 and be located on both sides of the housing 1, for transmitting power to both sides of the dual-output shaft reducer. This allows the reducer to simultaneously drive two sets of lifting transmission mechanisms targeting the ring rail and the yarn guide plate in both directions, avoiding the problem of the reducer body increasing in size due to the need to improve load-bearing capacity. It also solves the potential problem of inconsistent lifting actions between the two lifting transmission mechanisms when two unidirectional reducers transmit power to the two sets of lifting transmission mechanisms respectively, providing technical support for the development of extra-large spindle extra-long ring spinning machines.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
