Description

Technical Field

[0001] The invention relates to the technical field of traction machines, and in particular to a variable control high-efficiency energy-saving motor reducer assembly used for elevator driving. Background Art

[0002] The traction machine serves as the power source in the elevator braking system, and is synchronously equipped with a dedicated reducer structure and a motor structure. The reducer is essentially a conventional planetary reduction mechanism, which is used to change the output torque of the motor structure. Please refer to the relevant content mentioned in the publication number CN110040612A.

[0003] The gear structure inside the reducer will rotate according to a certain transmission ratio, so the torque conversion ratio is in a relatively constant state. According to the actual use requirements of the elevator, on the basis of changing the output power (torque) of the traction machine, it is also necessary to ensure that the elevator can operate stably, which requires a tight braking control system. However, because the reducer is a post-position device of the traction machine, the traction machine and the motor structure are the ones that "bear" the "work burden" when the torque changes. However, in the overall process, the gear structure in the reducer is mainly responsible for the torque change, which in the long-term operation will aggravate the wear of the gear structure or directly affect the operation process of the motor and directly affect the operation state of the elevator.

[0004] This application proposes a solution to this problem. Summary of the invention

[0005] The purpose of the present invention is to provide a variable control high-efficiency energy-saving motor reducer assembly for elevator drive, and the reducer structure matched with the elevator traction machine is explained. Because when the traction machine changes the output power, most of the work burden of the torque change is borne by the reducer or the motor itself, which is specifically reflected in the degree of wear between the internal gear structures, and directly affects the operating state of the elevator.

[0006] The object of the present invention can be achieved by the following technical solution: a variable control high-efficiency energy-saving motor reducer assembly applied to elevator drive, comprising a housing and a driving shaft, wherein a planetary gear plate and a planetary gear set are arranged inside the housing, and a cooperative component is arranged in the internal position of the housing corresponding to the planetary gear set and the driving shaft; The cooperative assembly includes a triangular cooperative block, an auxiliary steel cable and an auxiliary gear, wherein the auxiliary gear is arranged on the driving shaft, and the auxiliary gear is fixedly connected to the driving shaft, the triangular cooperative block is installed on the rotating shaft between the planetary gear set and the housing, and a rope groove for matching the auxiliary steel cable is arranged on the outer wall of the triangular cooperative block, and the auxiliary steel cable is wound on the triangular cooperative block through the rope groove; A directional sliding block corresponding to the auxiliary steel cable is arranged at an internal position of the shell corresponding to the cooperative component, and a cylinder sleeve corresponding to the directional sliding block is installed at an internal position of the shell, and an oil pressure auxiliary control module corresponding to the cylinder sleeve is arranged on the traction machine reducer assembly.

[0007] It is further configured that: the planetary gear set is composed of three planetary gears, the three planetary gears are arranged in a ring array along the driving shaft, the planetary gears are externally meshed with the driving shaft, and the driving shaft is rotationally connected to the housing; A planetary gear plate corresponding to the planetary gear is rotatably mounted inside the housing, the planetary gear plate is internally meshed with the planetary gear, and a shaft seat sleeve is mounted outside the planetary gear plate.

[0008] It is further configured as follows: the planetary gear is fixedly connected to the rotating shaft, and the center point of the planetary gear and the triangular cooperating block are on the same axis, the cross-section of the triangular cooperating block is an equilateral triangle arc, and the angles of the triangular positions of the triangular cooperating block are the same, and the arc lengths of the three side positions are the same.

[0009] It is further configured as follows: the number of triangular cooperative blocks is the same as the number of planetary gears, the setting angle of one triangular cooperative block is different from the setting angles of the triangular cooperative blocks in other positions, and the setting angles of the triangular cooperative blocks in other positions are the same.

[0010] It is further configured as follows: the auxiliary steel cable is provided with a first expansion portion and a second expansion portion through the setting angles of a plurality of triangular cooperating blocks, and the auxiliary steel cable is curved in an arch shape along a direction pointing to the cylinder sleeve through the first expansion portion and the second expansion portion.

[0011] It is further configured that: the setting positions of the first expansion part and the second expansion part match the setting angles of the triangular cooperating block.

[0012] It is further configured as follows: a through hole corresponding to the auxiliary steel cable is opened in the directional sliding block, and a cooperative roller is rotatably installed at the lower end of the directional sliding block close to the driving shaft, and the sliding direction of the directional sliding block in the shell is along the direction pointing to the center point of the driving shaft.

[0013] It is further configured as follows: the length of the cooperative roller is equal to the thickness of the auxiliary gear, the outer wall curved surface of the auxiliary gear is in a continuous wave shape, and the outer wall curved surface of the auxiliary gear matches the auxiliary gear.

[0014] It is further configured as follows: the end of the output shaft of the cylinder sleeve is fixedly connected to the center point of the outer curved surface of the directional sliding block, and the cylinder sleeve is matched with the oil pressure auxiliary control module.

[0015] The present invention has the following beneficial effects: The structure is basically the same as that of a conventional reducer, and a planetary reduction mechanism is used to achieve the purpose of reduction transmission. However, in view of the operating environment of the elevator, a cooperative working component is proposed on the basis of not changing the reduction transmission. Its essence lies in a triangular cooperative block that rotates in the same direction / speed as the planetary gear, and an auxiliary steel cable is added based on the structural shape of the triangular cooperative block. Under normal conditions, the length dimension of the auxiliary steel cable segment position is changed by changing the setting angle of one of the triangular cooperative blocks. Because the driving shaft is a power source structure, in the process of speed change, the driving shaft directly acts on the directional sliding block through the auxiliary gear, thereby changing the initial position of the directional sliding block, and directly feedbacks the operating effect inside the overall reducer through the change in oil pressure inside the cylinder sleeve; In combination with the above, it is explained again that: the auxiliary steel cable actively performs a cooperative "tension expansion action" during the transmission process of the planetary gear set, but it will also interfere with the winding process of the auxiliary steel cable through the auxiliary gear. Specifically, the first expansion part and the second expansion part are changed according to the setting angle of the triangular cooperative block. Therefore, during the overall operation, it can also directly interfere with the transmission process of the internal gear assembly by actively changing the oil pressure inside the cylinder sleeve.

DETAILED DESCRIPTION

[0019] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than 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] Embodiment 1: The motor + reducer structure of the elevator traction machine is described. When the traction machine changes its output power, the reducer bears most of the workload when the torque changes, which is especially reflected in the motor structure or the degree of wear between the internal gear structures, and directly affects the operation state of the elevator. In this regard, the present application proposes the following technical solutions: Reference Figures 1 to 7 The variable control high-efficiency energy-saving motor reducer assembly for elevator driving in this embodiment includes a housing 1 and a driving shaft 2, a planetary gear plate 3 and a planetary gear set 5 are arranged inside the housing 1, and a cooperative component is arranged in the internal position of the housing 1 corresponding to the planetary gear set 5 and the driving shaft 2; The cooperative assembly includes a triangular cooperative block 7, an auxiliary steel cable 6 and an auxiliary gear 11. The auxiliary gear 11 is arranged on the driving shaft 2, and the auxiliary gear 11 is fixedly connected to the driving shaft 2. The triangular cooperative block 7 is installed on the rotating shaft between the planetary gear set 5 and the housing 1, and a rope groove for matching the auxiliary steel cable 6 is arranged on the outer wall of the triangular cooperative block 7. The auxiliary steel cable 6 is wound on the triangular cooperative block 7 through the rope groove. A directional sliding block 10 corresponding to the auxiliary steel cable 6 is arranged at an internal position of the housing 1 corresponding to the cooperative assembly, and a cylinder sleeve 8 corresponding to the directional sliding block 10 is installed at an internal position of the housing 1, and a hydraulic auxiliary control module corresponding to the cylinder sleeve 8 is arranged on the traction machine reducer assembly, and the planetary gear set 5 is composed of three planetary gears, and the three planetary gears are arranged in a ring array along the driving shaft 2, and the planetary gears are externally meshed with the driving shaft 2, and the driving shaft 2 and the housing 1 are rotationally connected; A planetary gear plate 3 corresponding to the planetary gear is rotatably mounted inside the housing 1 . The planetary gear plate 3 and the planetary gear are internally meshed, and a shaft seat sleeve 4 is mounted outside the planetary gear plate 3 .

[0021] Basic working principle: The transmission process of the overall reducer is basically the same as that of the conventional reduction mechanism. The driving shaft 2 is used as the power input shaft, and the driving shaft 2 is used as the basic structure for connecting the motor structure. When the driving shaft 2 rotates at high speed, Figure 5 and Figure 4 , through the external meshing relationship between the planetary gears in the planetary gear set 5 and the driving shaft 2, they rotate synchronously, and again through the internal meshing relationship between the planetary gears in the planetary gear 5 and the planetary gear plate 3, they drive the planetary gear plate 3 to rotate, and drive the shaft seat sleeve 4 fixed to the outside of the planetary gear plate 3 to rotate synchronously. This part is the basic principle of the reducer.

[0022] Embodiment 2: This embodiment is based on the basic working principle of embodiment 1, and explains the cooperative components therein: The planetary gear is fixedly connected to the rotating shaft, and the center point of the planetary gear and the triangular cooperative block 7 are on the same axis. The cross section of the triangular cooperative block 7 is an equilateral triangle arc, and the angles of the triangular positions of the triangular cooperative block 7 are the same, and the arc lengths of the three sides are the same. The number of triangular cooperative blocks 7 is the same as the number of planetary gears, and the setting angle of one triangular cooperative block 7 is different from the setting angles of the triangular cooperative blocks 7 in the remaining positions, and the setting angles of the triangular cooperative blocks 7 in the remaining positions are the same. The auxiliary steel cable 6 is provided with a first expansion portion 601 and a second expansion portion 602 through the setting angles of multiple triangular cooperative blocks 7, and the auxiliary steel cable 6 passes through the first expansion portion 6 01 and the second expansion part 602 are in a curved arch shape along the direction pointing to the cylinder sleeve 8, the setting positions of the first expansion part 601 and the second expansion part 602 are matched with the setting angles of the triangular cooperative block 7, a through hole corresponding to the auxiliary steel cable 6 is opened in the directional sliding block 10, and a cooperative roller 9 is rotatably installed on the lower end position of the directional sliding block 10 close to the driving shaft 2, the sliding direction of the directional sliding block 10 in the shell 1 is along the direction pointing to the center point of the driving shaft 2, the length of the cooperative roller 9 is equal to the thickness of the auxiliary gear 11, the outer wall curved surface position of the auxiliary gear 11 is continuous wavy, and the outer wall curved surface of the auxiliary gear 11 matches the auxiliary gear 11.

[0023] Solution description: Supplementary description combined with the working principle of the first embodiment: the planetary gear is arranged inside the housing 1 through the rotating shaft. According to the planetary gear transmission principle, the planetary gear is only fixed to the rotating shaft, but the rotating shaft and the housing 1 keep rotating, so that the planetary gear keeps rotating instead of revolving around the driving shaft 2, so that the planetary gear plate 3 rotates; What needs to be explained about the rotating shaft is that the rotating shaft also needs to ensure that the triangular cooperative block 7 rotates synchronously. Figure 6 and Figure 7 The essence of the triangular cooperative block 7 is an equilateral triangle, but considering that the auxiliary steel cable 6 sets its three sides to arc surfaces, when the triangular cooperative block 7 rotates synchronously, the auxiliary steel cable 6 does not rotate synchronously. It is only because of the mutual switching process of the arc surface and the rounded corner position in the triangular cooperative block 7 that the length of the auxiliary steel cable 6 corresponding to the triangular cooperative blocks 7 at two adjacent positions is changed; It should be noted that in order to prevent the auxiliary steel cable 6 from being separated from the triangular cooperative block 7, the setting angle of one of the triangular cooperative blocks 7 is specially set to be different from the setting angles of the other two triangular cooperative blocks 7, so as to prevent the auxiliary steel cable 6 from being separated from the triangular cooperative block 7. Figure 6 For example, if the triangular cooperative block 7 at the upper right corner is numbered one, then they are numbered two and three in the clockwise direction, and the setting angles of the triangular cooperative blocks 7 of number two and three are exactly the same. In this case, only one complete arc surface of the triangular cooperative block 7 at position one is in contact with the auxiliary steel cable 6, and the other two triangular cooperative blocks 7 have one corner "holding" the auxiliary steel cable 6, so the length of the auxiliary steel cable 6 at the position of the first expansion portion 601 is slightly greater than the auxiliary steel cable 6 at the remaining two positions. Therefore, in this state, with the triangular cooperative block 7 The block 7 continues to rotate, and the setting angle is changed at a stable speed, then the length of the three sections of the auxiliary steel cable 6 "divided" by the three triangular cooperative blocks 7 changes regularly. In this case, because the length of the auxiliary steel cable 6 in the three sections changes, the "active" pulling directional sliding block 10 moves linearly along the length direction pointing to the center point of the active shaft 2. More specifically, the length of one section of the auxiliary steel cable 6 decreases, while the length of the other two sections of the auxiliary steel cable 6 increases, but the length of the entire auxiliary steel cable 6 does not change and does not leave the triangular cooperative block 7; The explanation of the oil cylinder sleeve 8 is: when the directional sliding block 10 moves linearly, it cooperates with the output shaft in the oil cylinder sleeve 8 to "passively" change the oil pressure in the oil cylinder sleeve 8; The auxiliary gear 11 is essentially a structural component fixed on the driving shaft 2. Compared with the planetary gear or the planetary gear plate, the auxiliary gear 11 can more directly sense the speed change of the driving shaft 2. On this basis, the outer wall surface of the auxiliary gear 11 is first limited to form a regular continuous wave shape, which is specifically required to cooperate with the cooperative roller 9 at the lower end of the directional sliding block 10. Figure 7 For example, combined with the directional sliding block 10 in the upper position, the cooperative roller 9 in this position is located at the concave surface of the outer wall of the auxiliary gear 11, but when the auxiliary gear 11 rotates stably, the convex surface on the outer wall of the auxiliary gear 11 moves to the position corresponding to the cooperative roller 9, thereby actively pushing the directional sliding block 10. The purpose of this working state is: in conjunction with the normal operating state of the reducer, the oil pressure changes in the three cylinder sleeves 8 can be used to feedback the operating efficiency of the internal gear structure of the reducer. More specifically, the oil pressure of one of the cylinder sleeves 8 is reduced, while the oil pressure inside the other two cylinder sleeves 8 is increased.

[0024] Embodiment 3: In combination with Embodiment 1 and Embodiment 2, an explanation about the cylinder sleeve is provided: The end of the output shaft of the oil cylinder sleeve 8 is fixedly connected to the center point of the outer curved surface of the directional sliding block 10, and the oil cylinder sleeve 8 is matched with the oil pressure auxiliary control module.

[0025] Solution description: First of all, in conjunction with the second embodiment, it is explained that the oil pressure change in the cylinder sleeve 8 can be actively changed by a matching oil pressure pump and other structures, which is specifically determined by the operating state of the reducer itself. When the power on the driving shaft 2 is constant, because the rotation state of the auxiliary gear 11 and the triangular co-acting block 7 is basically constant, the oil pressure change inside the cylinder sleeve 8 is in a relatively constant state of change. However, when the power on the driving shaft 2 changes, the driving shaft 2 always "responds" before the planetary gears and the planetary gear plate. In this state, because the planetary gears maintain their original rotation state under the influence of inertia, the driving shaft 2 drives the rotation state of the auxiliary gear 11. Changes occur, so it can be understood that there is a difference between the expansion state of the first expansion part 601 and the second expansion part 602 in the auxiliary steel cable 6 driven by the triangular cooperative block 7 and the expansion state of the first expansion part 601 and the second expansion part 602 in the auxiliary steel cable 6 driven by the auxiliary gear 11. Specifically, the oil pressure change in the cylinder sleeve 8 is directly fed back and combined with the oil pressure auxiliary control module to illustrate that the oil pressure change amplitude driven by the triangular cooperative block 7 is Q1, but after being "interfered" by the auxiliary gear 11, the oil pressure change amplitude at this position is less than or greater than Q1. In this state, the oil pressure in the cylinder sleeve is actively changed through structures such as a hydraulic pump to gradually restore stability.

[0026] In summary: the overall structure is changed according to the reducer structure used in the elevator traction machine, and a cooperative working component is proposed without changing the reduction transmission. Its essence lies in the triangular cooperative block that rotates in the same direction and speed as the planetary gear, and an auxiliary steel cable is added based on the structural shape of the triangular cooperative block. The auxiliary steel cable actively performs a cooperative "tension expansion action" during the transmission process of the planetary gear set, but it will also interfere with the winding process of the auxiliary steel cable through the auxiliary gear. Specifically, the first expansion part and the second expansion part are changed according to the setting angle of the triangular cooperative block. Therefore, during the overall operation, the transmission process of the internal gear assembly can be directly interfered with by actively changing the oil pressure change inside the cylinder sleeve, and the structural wear burden when the torque changes can be "actively assumed" by actively interfering with the oil pressure change inside the cylinder sleeve.
