Description

Technical Field

[0001] The invention belongs to the technical field of vacuum pump production and maintenance, relates to a vacuum pump motor, and in particular to a method for adjusting the axial positioning gap of a conical rotor. Background Art

[0002] The conical rotor brake motor is a three-phase asynchronous motor with built-in brakes and a conical stator and rotor. The conical rotor brake motor includes a housing, a stator assembly, a rotor assembly, a front seat, a rear seat, a brake male, a brake nut, and a screw disk for adjusting the rotor axial clearance. When the conical rotor brake motor is powered off, the brake nut is pressed against the brake male under the action of the spring. When powered on, the electromagnetic force generated by the rotor assembly will stretch the spring and push the brake nut open, separating it from the brake nut, so that the function of rotating when powered on and braking when powered off can be realized. The use of a conical rotor brake motor as the power source of the vacuum pump can effectively improve the start-stop performance of the equipment and help extend the actual service life of the equipment.

[0003] Since the axial clearance of the rotor assembly of the conical rotor brake motor in the stator assembly is directly related to the braking performance of the brake male and brake nut, if it is too tight, it will increase the resistance of the rotor, and if it is too loose, it will affect the braking performance of the motor. At present, the main adjustment function of the axial clearance of the rotor assembly is the screw disk located at the rear end of the brake nut; during the adjustment process, the screw disk is generally tightened by empirical methods. After tightening a certain number of turns, the shaft end of the motor is placed on the ground, and the separation of the brake nut and the brake male is observed by pressing the shell from top to bottom, thereby judging whether the clearance meets the working requirements of the motor. However, in this case, the clearance adjustment requires repeated measurements and repeated tightening of the screw disk, which affects the assembly efficiency and maintenance efficiency of the conical rotor brake motor.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear below, they only indicate that the upper, lower, left and right directions are consistent with the accompanying drawings themselves, and do not limit the structure.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0033] Examples, such as Figures 1 to 7 As shown, a method for adjusting the axial positioning gap of a conical rotor provided by the present invention includes a supporting tool 1, an overhead component 2, a pressurizing component 3 and a precision control component 4, and specifically includes the following steps:

[0034] S1. Level and place the support fixture 1, and assemble the front end seat 11, the rotor assembly 10, the stator assembly, the housing 9 and the rear end seat 12 with the brake male 13 on the support fixture 1 in sequence, wherein the front end seat 11 is supported on the overhead component 2, and the rotor assembly 10 is supported on the support fixture 1 with one axial end facing away from the brake nut 14 downward, and the other axial end of the rotor assembly 10 is upward;

[0035] S2, adjust the position of the overhead component 2 to the lowest position, and overhead the front end seat 11;

[0036] S3, press the brake end of the precision control component 4 against the edge of the top surface of the rear end seat 12, the precision control component 4 and the pressure component 3 are vertically movable, apply pressure to the pressure component 3 and make the precision control component 4 and the rear end seat 12 descend synchronously, the precision control component 4 is used to display the actual descending distance, and the descending distance is the working separation distance between the brake male 13 and the brake nut 14;

[0037] S4, install the brake nut 14 to the shaft end of the rotor assembly 10, install the screw plate 15 on the top of the rotor assembly 10 by screwing, and connect the screw plate 15 and the brake nut 14 with the positioning screws, so that the opposite surface of the screw plate 15 and the brake nut 14 are close to each other;

[0038] S5, the pressure-applying component 3 is decompressed, and the precision control component 4 and the rear end seat 12 are synchronously raised until the brake male 13 and the brake nut 14 are completely engaged.

[0039] By using a method for adjusting the axial positioning clearance of a conical rotor provided by the present invention, the axial movable clearance of the conical rotor brake motor is set before the brake nut 14 and the screw disk 15 are installed, and the screw disk 15 does not need to be adjusted repeatedly, which is beneficial to improving the assembly efficiency and maintenance efficiency. At the same time, in the process of adjusting the axial positioning clearance, the supporting tool 1 provides a supporting foundation and a bottom clamp for the assembly parts, and the overhead component 2 first supports and then performs the overhead function, while the precision control component 4 and the pressure component 3 are used to complete the control of the telescopic distance of the rotor assembly 10, so as to achieve the purpose of adjusting the separation distance between the brake male 13 and the brake nut 14, and then achieve the purpose of adjusting the positioning clearance of the rotor bearing.

[0040] In order to improve the performance of the supporting fixture 1 as a supporting base and bottom fixture, the supporting fixture 1 provided by the present invention includes a base 11, a supporting hole 12 is arranged at the center of the base 11, the top and bottom ends of the supporting hole 12 are respectively an upper supporting boss 13 and a lower supporting boss 14, a T-shaped supporting sleeve 15 is arranged at the center of the upper supporting boss 13, and the inner wall of the supporting sleeve 15 is provided with a spline hole 16 for matching with the shaft end of the rotor assembly 10. Among them, the upper supporting boss 13 and the lower supporting boss 14 can lengthen the axial length of the supporting hole 12, and the upper supporting boss 13 can support the lip of the front end seat 11; the spline hole 16 of the supporting sleeve 15 can play a centering role after being spline-connected with the shaft end of the rotor assembly 10, preventing the semi-assembled motor from tipping over after being suspended, and ensuring that the precision control component 4 can effectively contact the rear end seat 12. It should be noted that the supporting fixture 1 can be equipped with a bottom wheel at its bottom according to specific use needs to facilitate the transfer of the workstation.

[0041] In order to improve the performance of the overhead component 2 in terms of support and overhead capacity, the overhead component 2 provided by the present invention includes a plurality of lifting modules 21 distributed in a circular array and used to support the front end seat 11. The inner and outer surfaces of the lifting modules 21 are both arc-shaped. The lifting modules 21 are provided with screw holes near both ends thereof, and a screw shaft 22 is provided in the screw hole to rotate with the lifting module 21. The screw shaft 22 passes through the upper and lower surfaces of the supporting tooling 1 and is provided with a driven gear 23 connected to the driven gear 23. The driven gear 23 is located inside the supporting tooling 1 and is provided with a composite gear ring 24 that is meshed with all the driven gears 23 on its outer side. The composite gear ring 24 includes an inner gear ring 241 and an outer gear ring 242. A driving gear 25 that is meshed with the driving gear 23 is provided on the outer side of the outer gear ring 242. A transmission groove 17 for assembling the driving gear 25 is provided on the supporting tooling 1. A transmission sealing cover 26 is provided on the top of the transmission groove 17. A rocker arm 27 that is connected to the driving gear 25 is provided at the center of the transmission sealing cover 26. To match the overhead component 2, the bottom of the support fixture 1 is a hollow structure for installing the transmission part of the overhead component 2. The transmission part of the overhead component 2 uses a driving gear 25 to drive the outer ring gear 242, and the outer ring gear 242 rotates synchronously with the inner ring gear 241. The inner ring drives all the driven gears 23 at the same time, thereby ensuring that the lifting data of all lifting modules 21 are changed synchronously. More specifically, the power is transmitted to the driving gear 25, the composite ring gear 24 and the driven gear 23 by rotating the rocker arm 27, and the driven gear 23 rotates synchronously with the screw shaft 22, thereby controlling the lifting module 21 at a reasonable height. The support diameter formed by all lifting modules 21 is smaller than the maximum outer diameter of the front end seat 11, so that the front end seat 11, the rotor assembly 10, the housing 9, the stator assembly and the rear end seat 12 can be effectively supported. Before the gap is adjusted, the lifting module 21 always maintains a supporting relationship with the front end seat 11. After the rear end seat 12 is assembled, the height of the lifting module 21 is lowered by rotating the rocker arm 27 to maintain a sufficient vertical distance between the front end seat 11 and the lifting module 21 to ensure that when the rear end seat 12 is subsequently pressed down, the rotor assembly 10 and the housing 9 can produce an ideal axial difference, that is, an axial gap.

[0042] In order to improve the transmission performance of the compound gear ring 24 and the driven gear 23, from the perspective of assembly relationship, the hollow position of the support fixture 1 provided by the present invention is provided with a transmission clamping plate 5 for assembling the compound gear ring 24, and the transmission clamping plate 5 is provided with an axial eye for cooperating with the shaft end of the screw shaft 22, which is used to limit the plane position of the screw shaft 22 and the driven gear 23. At the same time, in order to ensure the assembly reliability of the transmission clamping plate 5, the present invention is provided with a positioning plate 6 at the bottom of the transmission clamping plate 5 which is flange-connected to the bottom of the support fixture 1 to prevent the transmission clamping plate 5 from being dislocated under the pressure of the transmission component.

[0043] Furthermore, the transmission splint 5 provided by the present invention is an annular structure, and the transmission splint 5 includes a groove section 51 nested with the inner wall of the supporting tooling 1, and a first annular aperture groove 52 is arranged on the top of the groove section 51, and a flat ring section 53 is arranged on the groove section 51, and the top surface of the flat ring section 53 cooperates with the shoulder of the screw shaft. The compound ring gear 24 includes a first welding plate 243 arranged at the bottom of the inner ring gear 241 and a second welding plate 244 arranged on the outside of the inner ring gear 241. The inner ring gear 241 and the outer ring gear 242 are welded to the first welding plate 243 and the second welding plate 244 in an up-and-down staggered manner. The cross-section of the first welding plate 243 is T-shaped and its bottom is rotatably matched with the first aperture groove 52. Among them, the assembly position of the outer gear ring 242 is lower than the assembly position of the inner gear ring 241. If the inner gear ring 241 is in a high position, the position of the driven wheel matched therewith is also high, so that the transmission clamp plate 5 and the inner top surface of the support fixture 1 can form a relatively moderate vertical assembly space, avoiding the axial movement of the driven gear 23 and affecting the transmission performance of the transmission part; if the outer gear ring 242 is in a low position, the driving gear 25 is also in a relatively low position, which is conducive to the driving gear 25 and the transmission node of the rocker arm 27 and the transmission sealing cover 26 to maintain a relatively long distance, so as to ensure the smoothness and stability of the rotation of the rocker arm 27. As for the transmission clamp plate 5, the transmission clamp plate 5 is in a predetermined position in the support fixture 1, and no rotation, end swing and axial movement occur. The first aperture groove 52 provides smooth support for the support part of the first welding plate 243, that is, the groove wall of the first aperture groove 52 is smooth, finely turned and polished, and while providing support, it acts as a bearing to reduce the transmission resistance of the composite gear ring 24.

[0044] In order to improve the rotation performance of the composite gear ring 24, the top of the second welding plate 244 provided by the present invention is rotatably matched with the second aperture groove 18 set at the top of the support fixture 1, and the groove wall of the second aperture groove 18 is smooth, finely turned and polished, and while providing support, it acts as a bearing to reduce the transmission resistance of the composite gear ring 24. In this way, the composite gear ring 24 can establish a stable rotating working surface between the support fixture 1 and the transmission clamping plate 5 through the first welding plate 243 and the second welding plate 244, effectively reducing the probability of obvious end swing and radial runout, thereby ensuring the transmission performance of the transmission part of the overhead component 2.

[0045] In order to improve the utilization rate of the support fixture 1, the central bottom of the support fixture 1 provided by the present invention is provided with a top pressing seat 7 which is threadedly matched therewith, and the side surfaces of the support fixture 1 and the transmission clamping plate 5 are provided with a plurality of plate-shaped holes 8 corresponding to the height of the top pressing seat 7, and the plate-shaped holes 8 are used to pass the tool for adjusting the top pressing seat 7. The top surface of the top pressing seat is supported and matched with the bottom end of the rotor assembly, and the height of the end of the rotor assembly can be adjusted by adjusting the matching depth between the top pressing seat 7 and the support hole 12, thereby meeting the assembly and adjustment requirements of conical rotor brake motors of different specifications, and facilitating improving the accuracy of the axial clearance adjustment operation.

[0046] In order to improve the stability of the conical rotor brake motor after being suspended by the overhead component 2, especially the deflection situation, a radial slide plate 28 is provided between the adjacent lifting modules 21 provided by the present invention, a slide bar 281 is provided at both ends of the radial slide plate 28, an adjusting screw 29 is provided at the center of the slide bar 281 to cooperate with its thread, the slide bar 281 cooperates with the slide groove provided on the lifting module 21, and the adjusting screw 29 cooperates with the screw hole provided at the end of the slide groove, and a thorn plate 282 is provided at the bottom of the radial slide plate 28 for radially positioning the front end seat 11 after being suspended, the cross section of the thorn plate 282 is an arc, and the top surface of the thorn plate 282 is a slope surface. Among them, the quasi-circular clamping caliber formed by all the thorn plates 282 is slightly larger than the maximum outer diameter of the front end seat 11, the inner wall of the thorn plate 282 is used to radially limit the edge of the front end seat 11, and the actual position of the thorn plate 282 and the radial slide plate 28 on the lifting module 21 is controlled by the adjusting screw 29. The matching position of the adjusting screw 29 in the screw hole is manually rotated and adjusted, and the rotating action of the adjusting screw 29 can be converted into the relative sliding action of the slide bar 281 and the slide groove, thereby controlling the actual radial position of the radial slide plate 28 and the thorn plate 282. The maximum height of the thorn plate 282 is greater than the maximum adjustment requirement of the axial clearance. After the overhead component 2 suspends the conical rotor brake motor, the inner wall of the thorn plate 282 always maintains the original clamping diameter, and its highest position does not leave the highest surface of the front end seat 11, so it can effectively ensure that the conical rotor brake motor is always kept in the axial position within the error allowable range after being suspended by the overhead component 2, and effectively avoid the shear stress at the root of the rotor assembly 10 from increasing as a side effect and affecting the subsequent axial clearance accuracy.

[0047] In order to improve the matching performance between the precision control component 4 and the rear end seat 12, the precision control component 4 provided by the present invention includes a base plate 41, a vertical shaft 42 is arranged at one end of the base plate 41, a pressure plate 43 is arranged on the side of the vertical shaft 42, the pressure plate 43 is in a "7" shape, the inner side surface of the pressure plate 43 is reinforced with reinforcing ribs, and a shaft head 44 is arranged on the top of the vertical shaft 42.

[0048] In coordination with the precision control component 4, the pressurizing component 3 provided by the present invention includes a fixed axis rod 31 fixedly connected to the supporting tooling 1, a scale rod 32 is arranged on the top of the fixed axis rod 31, the scale rod 32 is movably matched with the light hole arranged on the base plate 41, a length scale is arranged on the scale rod 32 and a spring 33 is sleeved on its outer side, the two ends of the spring 33 are respectively in pressure contact with the base plate 41 and the fixed axis rod 31, a pressurizing plate 34 connected to the fixed axis rod 31 by a key is arranged on the fixed axis rod 31, a bayonet 35 movably matched with the shaft head 44 is arranged on the side of the pressurizing plate 34, a fixing nut 36 is arranged on the top of the pressurizing plate 34, the fixing nut 36 is used to extend the matching surface between the pressurizing plate and the scale rod, a pipe sleeve 37 threadedly connected to the fixed axis rod 31 is arranged on the top of the fixing nut 36, a power input member 38 is arranged on the pipe sleeve 37, and the power input member 38 can be a manual structure such as a hand wheel, or it can be a small stepping motor. Specifically, during the assembly of the front end seat 11, the rotor assembly 10, the stator assembly, the housing 9 and the rear end seat 12, the precision control component 4 can be rotated away from the assembly range by manual toggle, and when adjusting the axial positioning clearance, the pressure plate 34 is raised, and then the shaft head 44 of the precision control component 4 is rotated to the bayonet 35, and the braking surface of the pressure plate 43 acts on the edge of the top surface of the rear end seat 12; after the rotational power is input through the power input member 38 and the sleeve 37, the sleeve 37 presses the pressure plate 43 and the precision control component 4 to produce a descending action. At the same time, the bottom plate 41 of the precision control component 4 serves as both a support member and a pointer member, mainly the upper surface of the bottom plate 41, which cooperates with the length scale on the fixed shaft rod 31 to accurately mark the distance that the sleeve 37 needs to be adjusted to descend. The descending distance is the axial positioning clearance that meets the assembly requirements, that is, the clutch distance between the brake male 13 and the brake female 14, which is generally 3 to 8 mm. The role of the spring 33 in the pressurizing component 3 is, on the one hand, to elastically support the precision control component 4 so that the precision control component 4 and the fixed axis rod 31 have a stable and accurate scale marking effect; on the other hand, it can prevent the shaft head 44 from accidentally disengaging from the bayonet 35 under pressure and affecting the efficiency and safety of adjusting the axial positioning gap.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
