[0065] The elevator traction machine provided by the utility model improves the disadvantages of the existing split-structure steel belt traction machine and solves the problem of large cumulative errors formed during the assembly process of the split-structure elevator traction machine by improving the machine base of the elevator traction machine.

[0066] The elevator traction machine of the present invention adopts a machine base with an integrated structure, which not only improves the overall rigidity and strength of the elevator traction machine, as well as the safety performance, but also reduces the number of connecting parts, thereby appropriately reducing the overall weight of the elevator traction machine and reducing processing costs.

[0067] In terms of the processing of the machine base, the overall structure of the machine base no longer requires separate processing of each split structure. During processing, the entire base can be positioned at one time or based on the same reference, and multiple positions can be machined. Therefore, the overall structure of the machine base not only improves the processing accuracy, but also reduces the processing cost.

[0068] The elevator traction machine and the base of the present invention are described in detail below with reference to the accompanying drawings. The accompanying drawings are only used to illustrate the elevator traction machine and the base of the present invention and cannot be understood as limiting the present invention.

[0069] Figure 1 This is a structural diagram of the brake side of the elevator traction machine according to an embodiment of the present utility model. Figure 2 This is a structural diagram of one side of the installation drum of the elevator traction machine according to an embodiment of the present utility model. Figure 3 for Figure 1 AA section view, combined with Figure 1 、 Figure 2 and Figure 3 The elevator traction machine 10 of the present invention includes a machine base 100 with an integrated structure, wherein the machine base 100 includes a mounting tube 110, a first support seat 120 and a second support seat 130; the first support seat 120 is arranged at one end of the mounting tube 110, and the second support seat 130 is located on the side of the first support seat 120 away from the mounting tube 110, and is spaced apart from the first support seat 120, and the first support seat 120 and the second support seat 130 brackets are connected by a support assembly 140.

[0070] like Figure 3 As shown, the elevator traction machine 10 also includes a rotor assembly 400, a stator assembly 300, a rotating shaft 500 and a traction wheel 600, wherein the stator assembly 300 is arranged on the rotating shaft 500, and the stator assembly 300 and the rotor assembly 400 are cooperatively installed in the mounting tube 110 of the machine base 100 to constitute a motor device for driving the rotating shaft 500 to rotate.

[0071] One end of the rotating shaft 500 extends out of the mounting tube 110 of the machine base 100, and is sequentially passed through the first support seat 120 and the second support seat 130, and a traction wheel 600 is provided on the partial shaft section of the rotating shaft 500 located between the first support seat 120 and the second support seat 130, so that the motor device can drive the rotating shaft 500 and the traction wheel 600 to rotate together.

[0072] The elevator traction machine 10 of this embodiment further includes a braking device 700 , which is disposed on a side of the second support base 130 away from the second support base 130 and is used to brake the rotating shaft 500 to control the start and stop of the traction sheave 600 on the rotating shaft 500 .

[0073] In the elevator traction machine 10 of this embodiment, the stator assembly 300 and the rotor assembly 400 are both arranged in the installation tube 110 of the machine base 100, the braking device 700 is arranged on the outside of the second support seat 130, and the traction sheave 600 is arranged between the first support seat 120 and the second support seat 130. The entire machine maintains a stable state under the support of the first support seat 120 and the second support seat 130; whether the rotating shaft 500 drives the traction sheave 600 to rotate under the interaction of the rotor assembly 400 and the stator assembly 300 in the motor device, or the rotating shaft 500 and the traction sheave 600 are braked under the action of the braking device 700, the machine base 100 with an integrated structure can maintain a high stability.

[0074] The integrated structure of the machine base 100 is also beneficial for the elevator traction machine 10 to withstand a larger load, especially for a large-tonnage steel belt elevator traction machine 10. When the elevator traction machine 10 is started or during braking, the rotating shaft 500 is subjected to a large load, which is ultimately transferred to the machine base 100. The machine base 100 of the present invention is an integrated structure with high overall strength, which can well disperse the load and maintain a high stability under the action of the first support base 120, the second support base 130 and the support assembly 140.

[0075] Figure 11 FIG. 1 is a schematic structural diagram of the rotating shaft of the elevator traction machine according to an embodiment of the present invention, as shown in FIG. Figure 11 As shown, the traction sheave 600 of the elevator traction machine 10 is integrally formed with the rotating shaft 500 , thereby improving the load-bearing capacity and stability of the rotating shaft 500 .

[0076] The rotating shaft 500 is provided with a plurality of shaft segments 510 for winding traction members such as steel belts. Figure 11 The rotating shaft 500 is provided with four shaft sections 510. The axial ends of each shaft section 510 are higher to form a groove section suitable for accommodating the steel belt, which is conducive to the traction part of the steel belt being stably wound in each groove section.

[0077] Figure 12 for Figure 11 The enlarged view of the C part is as follows: Figure 12 As shown, the outer surface of the shaft segment 510 on the rotating shaft 500 for winding the steel strip is an outward convex arc segment. In order to clearly illustrate the arc shape of each shaft segment 510, Figure 12 A horizontal reference line 512 is also provided as a comparison object. In the elevator traction machine 10 in this embodiment, the intersection line between the surface of the multiple shaft segments 510 on the rotating shaft 500 and the plane passing through the central axis of the rotating shaft 500 is set to be an arc shape. The arc-shaped intersection line 511 can make the steel belt more stably wound on the shaft segment 510 on the rotating shaft 500.

[0078] That is, a shaft segment for winding the traction member is provided on the rotating shaft, and the shaft segment is in an arc shape along the direction of the central axis of the rotating shaft.

[0079] Combine Figure 11 It can also be seen that four shaft segments 510 are provided on the rotating shaft 500 for winding steel belts and other traction machines. Among them, two shaft segments 510 are provided on the side close to the first support seat 120, and two shaft segments 510 are provided on the side close to the second support seat 130. This can make the rotating shaft 500 bear the load stably; avoid the first support seat 120 side or the second support seat 130 side bearing a large load, which may cause local instability in the operation of the elevator traction machine 10.

[0080] Among them, a plurality of slot sections are provided on the rotating shaft 500 for carrying the winding traction member. Figure 10 Four slot segments are shown; when multiple slot segments are set, the number of slot segments close to the first support seat 120 should be consistent with the number of slot segments close to the second support seat 130. This arrangement allows the first support seat 120 and the second support seat 130 to bear the load evenly respectively, avoiding the load concentration on the first support seat 120 or the second support seat 130.

[0081] In one embodiment of the present invention, the elevator traction machine 10 further includes a protection assembly 800, which is disposed above the traction sheave 600 and distributed on both sides of the traction sheave 600. Specifically, Figure 5 and Figure 6 The protective component 800 includes a first plate-shaped member 810 and a second plate-shaped member 820 arranged adjacent to each other. The first plate-shaped member 810 and the second plate-shaped member 820 are both connected to the support component 140. The first plate-shaped member 810 and the second plate-shaped member 820 are arranged above the shaft section 510 of the rotating shaft 500 for winding traction members such as steel belts. The first plate-shaped member 810 is arranged on one side of the rotating shaft 500, and the second plate-shaped member 820 is arranged on the other side of the rotating shaft 500, and is located on both sides of the rotating shaft 500.

[0082] The elevator traction machine 10 of this embodiment is provided with a first plate-shaped member 810 and a second plate-shaped member 820 on both sides of the groove section of the rotating shaft 500, respectively, which can prevent foreign matter from entering the shaft section 510 of the rotating shaft 500, thereby avoiding adverse effects on traction parts such as steel belts when the elevator traction machine 10 is running.

[0083] Figure 7 This is a three-dimensional diagram of the base of the elevator traction machine according to an embodiment of the present invention. Figure 8 This is a three-dimensional diagram of the base of the elevator traction machine according to an embodiment of the present invention from another perspective, combined with Figure 7 and Figure 8 ,as well as Figure 3It can be seen that an installation cavity 111 is provided in the installation cylinder 110 of the machine base 100, and an installation opening 112 is provided at one end of the installation cavity 111 for installing the stator assembly 300 and the rotor assembly 400; the first support seat 120 is arranged at the other end of the installation cavity 111 and is connected to the installation cylinder 110. Along the central axis direction of the installation cylinder 110, the second support seat 130 and the first support seat 120 are arranged at intervals and are connected through the support assembly 140.

[0084] The machine base 100 in this embodiment is an integrated structure, which can improve the overall rigidity and strength of the machine base 100, so that the elevator traction machine 10 has higher safety performance both during operation and braking.

[0085] Compared with the split structure, the integrated structure of the machine base 100 no longer requires individual processing of each component, and no longer requires precise processing of the matching positions between different components, thereby reducing the processing cost of the entire machine base 100.

[0086] At the same time, the base 100 of the integral structure can also reduce unnecessary connecting parts and supporting parts compared with the split structure, and its weight can be appropriately reduced.

[0087] like Figure 7 and Figure 8 As shown, a first bearing chamber 121 is provided in the first support seat 120 of the machine base 100. The first bearing chamber 121 is connected to the mounting cavity 111 of the mounting cylinder 110. Along the central axis direction of the mounting cavity 111 of the mounting cylinder 110, the first bearing chamber 121 is provided with a through hole 122.

[0088] The second support seat 130 of the machine base 100 is provided with a second bearing chamber 131 . The second bearing chamber 131 has a mounting hole 132 for coupling with the bearing. The inner diameter of the mounting hole 132 is smaller than the inner diameter of the through hole 122 .

[0089] When installing the elevator traction machine 10, the machine base 100 in this embodiment can sequentially install the second bearing 220 in the second bearing chamber 131 and the first bearing 210 in the first bearing chamber 121 on the side of the installation opening 112 of the installation cylinder 110. Because the inner diameter D1 of the through hole 122 of the first bearing chamber 121 is larger than the inner diameter D3 of the installation hole 132 of the second bearing chamber 131, the second bearing 220 can pass through the through hole 122 on the side of the installation opening 112 of the installation cylinder 110 and then be installed in the second bearing chamber 131.

[0090] During disassembly, the first bearing 210 and the second bearing 220 can be removed in sequence from one side of the mounting port 112 of the mounting cylinder 110 without removing the braking device 700 on the other side of the second support seat 130. Therefore, the machine base 100 in this embodiment has the advantage of being easy to install and replace the first bearing 210 and the second bearing 220.

[0091] The installation steps of the elevator traction machine 10 of the present invention may refer to the installation steps of the first bearing 210 and the second bearing 220 in the machine base 100, which are described together here.

[0092] When installing the elevator traction machine 10, the second bearing 220 and the first bearing 210 as well as the rotor assembly 400 and the rotor retaining ring can be installed on the rotating shaft 500 in sequence. Then, the rotating shaft 500 with the second bearing 220, the first bearing 210, the rotor assembly 400 and the rotor retaining ring are passed through the installation opening 112 and the through hole 122 in sequence, and the second bearing 220 is installed in the installation hole 132 of the second bearing 220 seat. The first bearing 210 is installed in the first bearing chamber 121 of the first support seat 120, and the pressure covers of the first bearing chamber 121 and the second bearing chamber 131 are installed at the same time to seal the first bearing chamber 121 and the second bearing chamber 131. Finally, the stator assembly 300 is pressed into the installation cavity 111 of the installation cylinder 110, and the installation opening 112 of the installation cylinder 110 is sealed.

[0093] The machine base 100 in this embodiment, and the elevator traction machine 10 using the machine base 100, can complete the installation of the first bearing 210, the second bearing 220, the rotor assembly 400 and the rotating shaft 500 on one side of the installation opening 112 of the installation cylinder 110 without removing the braking device 700 on the other side of the second support base 130; at the same time, it also facilitates the replacement of the second bearing 220 and the first bearing 210.

[0094] In one embodiment of the present invention, Figure 7 and Figure 8 The second bearing chamber 131 is provided with an oil retaining ring 133 on the side away from the first bearing chamber 121. The provision of the oil retaining ring 133 can prevent the lubricating grease in the second bearing chamber 131 from leaking outward, thereby preventing the grease in the second bearing chamber 131 from overflowing onto the brake device 700, thereby avoiding the end face of the friction pair of the brake device 700 being affected by the grease and causing the braking torque to decrease, while reducing the safety hazards caused by this.

[0095] In this embodiment, the machine base 100 is provided with an oil retaining ring 133 in the second bearing chamber 131 , which not only reduces grease leakage in the second bearing chamber 131 but also improves the safety performance of the entire elevator traction machine 10 .

[0096] In one embodiment of the present invention, Figure 7 、 Figure 8 and Figure 9 A support assembly 140 is provided between the first support base 120 and the second support base 130 of the machine base 100. The support assembly 140 is connected to the first support base 120 and the second support base 130 respectively, connecting the first support base 120 and the second support base 130 into one body.

[0097] Specifically, the support assembly 140 includes a first support member 141 and a second support member 142, the first support member 141 is connected to the first support seat 120 and the second support seat 130, the second support member 142 is connected to the first support seat 120 and the second support seat 130, and the first support member 141 and the second support member 142 are spaced apart. Figure 7 、 Figure 8 and Figure 9 It can also be seen that the first support member 141 is arranged on the upper part of the first support seat 120 and the second support seat 130, and the second support member 142 is arranged on the lower part of the first support seat 120 and the second support seat 130; thereby, the steel belt and other traction members can be wound on the traction wheel 600 between the first support seat 120 and the second support seat 130 through the space between the first support member 141 and the second support member 142.

[0098] In order to improve the connection strength and rigidity, one end of the first support member 141 may be extended to the outer wall of the installation tube 110 , and one end of the second support member 142 may be extended to the outer wall of the installation tube 110 .

[0099] Figure 10 for Figure 9 The BB section view is as follows: Figure 10 As shown, the first support member 141 can be set as a T-shaped rib, and the second support member 142 can be set as a T-shaped rib, which can improve the bending resistance of the first support member 141 and the second support member 142 between the first support seat 120 and the second support seat 130, so that the machine base 100 can withstand a larger impact load.

[0100] In one embodiment of the present invention, Figure 7 A plurality of first reinforcing ribs 123 are also provided on the first support seat 120 of the machine base 100. The plurality of first reinforcing ribs 123 are arranged at intervals along the axial direction of the first bearing chamber 121 of the first support seat 120. One end of the first reinforcing rib 123 is connected to the outer wall of the first bearing chamber 121, and the other end of the first reinforcing rib 123 is connected to the first support seat 120 to improve the structural strength of the first support seat 120.

[0101] The first reinforcing rib 123 is connected to the outer wall of the first bearing chamber 121 . On the one hand, it can support the first bearing chamber 121 . On the other hand, it can also dissipate heat from the first bearing chamber 121 , thereby dissipating more heat from the first bearing chamber 121 to the outside.

[0102] In order to improve the stability of the first support base 120, as Figure 7 As shown, a first groove 124 is provided on the bottom wall of the first support seat 120. The first groove 124 can be provided as a C-shaped groove, a trapezoidal groove or other specific structures to make the bottom contact area of ​​the first support seat 120 smaller, thereby avoiding the influence of the machining accuracy of the flatness of the bottom of the first support seat 120 on the stability of the machine base 100.

[0103] In one embodiment of the present invention, Figure 8 A plurality of second reinforcing ribs 135 are provided on the second support seat 130 of the machine base 100, and the plurality of reinforcing ribs are arranged at intervals along the circumference of the second bearing chamber 131. One end of the second reinforcing rib 135 is connected to the outer wall of the second bearing chamber 131, and the other end of the second reinforcing rib 135 is connected to the second support seat 130 to improve the structural strength of the second support seat 130.

[0104] Two third reinforcing ribs 136 are also provided on the second support seat 130, which are respectively connected to the outer wall of the second bearing chamber 131 and the second support seat 130. The two third reinforcing ribs 136 are provided at the lower part of the second support seat 130, and the two third reinforcing ribs 136 are arranged at an angle. For example, the two third reinforcing ribs 136 are both inclined, and the angle between the extension lines of the two third reinforcing ribs 136 is 60°, so as to improve the structural strength of the second support seat 130.

[0105] A second reinforcing rib 135 and a third reinforcing rib 136 connected to the outer wall of the second bearing chamber 131 are arranged on the second support seat 130, which can also improve the load-bearing capacity of the second support seat 130. For example, the inclined arrangement of the two third reinforcing ribs 136 can enable the second support seat 130 to withstand a greater impact load.

[0106] In addition, the second reinforcing ribs 135 and the third reinforcing ribs 136 can also play a heat conducting role, transferring the heat generated in the second bearing chamber 131 to the outside in a timely manner and dissipating it as quickly as possible to reduce the high temperature impact on the grease in the second bearing chamber 131 and the second bearing 220.

[0107] In some embodiments of the present invention, a first reinforcing rib 123 can be provided on the first support seat 120, and a second reinforcing rib 135 and a third reinforcing rib 136 can be provided on the second support seat 130, wherein the first reinforcing rib 123, the second reinforcing rib 135 and the third reinforcing rib 136 can also serve as heat dissipation ribs 113 to dissipate heat for the first bearing chamber 121 of the first support seat 120 and the second bearing chamber 131 of the second support seat 130, and heat dissipation ribs 113 can also be provided on the outer wall of the mounting tube 110 of the machine base 100 to dissipate heat generated by the rotor assembly 400 in the mounting cavity 111 during rotation to the outside.

[0108] like Figure 8 As shown, a second groove 137 is further provided at the bottom of the second support seat 130 to improve the stability of the second support seat 130. The second groove 137 can be provided with a C-shaped groove or a trapezoidal groove or other structures to reduce the contact area of ​​the bottom of the second support seat 130 to avoid the influence of insufficient processing accuracy on the flatness of the bottom of the second support seat 130.

[0109] The second groove 137 of the second support base 130 , combined with the first groove 124 of the first support base 120 , can improve the stability of the connection between the machine base 100 and the machine room, and improve the load bearing capacity of the elevator traction machine 10 .

[0110] In summary, the machine base 100 of the present invention is described in detail in combination with specific embodiments and drawings. The machine base 100 of the present invention is applied to the elevator traction machine 10, which makes the elevator traction machine 10 more stable and improves its ability to withstand impact. At the same time, it is more conducive to the installation and replacement of the first bearing 210 and the second bearing 220.

[0111] Other embodiments of the elevator traction machine 10 of the present invention will be described below with reference to the accompanying drawings.

[0112] The elevator traction machine 10 of the present invention includes a machine base 100 as in any of the above embodiments, and also includes a stator assembly 300 and a rotor assembly 400 arranged in the installation cavity 111 of the installation cylinder 110, and a rotating shaft 500 passing through the installation cavity 111, the first bearing 210 of the first support seat 120 and the second bearing 220 of the second support seat 130, and a traction sheave 600 arranged on the rotating shaft 500 and located between the first support seat 120 and the second support seat 130.

[0113] The traction sheave 600 can be fixed to the rotating shaft 500 , for example, by an interference fit, a shaft key connection, or a spline shaft connection.

[0114] The traction sheave 600 and the rotating shaft 500 may also be integrally formed to improve the connection strength and stability between the rotating shaft 500 and the traction sheave 600 .

[0115] In one embodiment of the elevator traction machine of the present invention, Figure 3 and Figure 4 The elevator traction machine includes a bearing assembly 200, which includes a first bearing 210 and a second bearing 220. The first bearing 210 is arranged in the first bearing chamber 121 of the first support seat 120 of the machine base 100, for positioning the rotating shaft 500. The second bearing 220 in the second bearing chamber 131 of the second support seat 130 is provided with a radial gap 230 with the mounting hole 132. That is, the inner diameter D3 of the mounting hole is larger than the outer diameter D2 of the second bearing. In the radial direction, the outer ring of the second bearing 220 is clearance-matched with the inner wall of the mounting hole 132. Setting the second bearing 220 to a floating state can improve the environmental adaptability of the elevator traction machine 10.

[0116] When the temperature in the second bearing chamber 131 is high, or when the rotating shaft 500 is affected by high temperature, or when the second bearing 220 is affected by high temperature, the radial deformation generated can be released between the radial gap 230 between the second bearing 220 and the mounting hole 132, so as to reduce the stress impact and local deformation on the second support seat 130, thereby affecting the normal operation of the elevator traction machine 10.

[0117] Since the brake device 700 is provided on the outer side of the second support base 130 of the machine base 100 of the elevator traction machine 10, the influence of stress concentration or stress deformation on the brake device 700 can be reduced.

[0118] In one embodiment of the present invention, Figure 7 A boss 134 is provided on the side of the second support seat 130 facing away from the first support seat 120 , and a plurality of connection positions are provided on the boss 134 for connecting the braking device 700 .

[0119] Combine Figure 6 , wherein the braking device 700 includes a first brake 710 and a second brake 720. The first brake 710 and the second brake 720 are independently arranged to brake the rotating shaft 500. The advantage of such an arrangement is that when the first brake 710 or the second brake 720 fails, the elevator traction machine 10 still has good braking ability.

[0120] like Figure 6 As shown, the first brake 710 and the second brake 720 are both provided with a semicircular structure, and the two semicircular brakes form a disc-shaped structure. In the braking state, the first brake 710 and the second brake 720 press the brake disc 730 against the movable plate of the brake through the spring, and then the movable plate of the brake presses the brake disc 730 against the end face of the machine base 100, thereby braking the rotating shaft 500.

[0121] In the brake release state, the first brake 710 and the second brake 720 no longer press the brake movable plate through the spring, so that the brake disc 730 is no longer subjected to the force of the brake movable plate. A gap is formed between the brake disc 730 and the end face of the machine base 100, and the rotating shaft 500 and the traction wheel 600 can rotate under the action of the motor device.

[0122] The brake disc 730 and the rotating shaft 500 are connected in a spline manner.

[0123] The utility model also provides an elevator device, which includes the elevator traction machine as described above and the machine base as described above.

[0124] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
