Description
Technical Field
[0001] The utility model relates to the technical field of planetary frame detection, in particular to a planetary frame detection device for a reduction gearbox. Background Art
[0002] A reduction gearbox is a mechanical transmission device whose main function is to reduce the speed of the input shaft and increase the output torque so that the power transmission meets the actual needs of the working equipment. For example, in some large cranes, the high-speed, low-torque output of the motor is converted into low-speed, high-torque output through the reduction gearbox, thereby achieving smooth lifting of heavy objects.
[0003] The planetary carrier is one of the main components of the planetary gear transmission. The planetary shafts or bearings are installed on the planetary carrier. It is the part that bears the largest external torque in the device. The structural design and manufacturing of the planetary carrier have a great impact on the load distribution between the planetary gears and the load-bearing capacity of the entire transmission device.
[0004] When using the gearbox planetary carrier detection device, the planetary carrier needs to be fixed first, and then the pins are measured with a caliper and then compared with the required data. However, it is found that the measurement error of this method is large during use, and it is difficult to reflect the real data of the planetary carrier.
[0005] Therefore, in order to solve the above problems, a reduction gearbox planetary carrier detection device is proposed. Utility Model Content

[0008] Preferably, the fixing assembly includes a plurality of fixing rods; the fixing rods and the bearing seat are in a fixed connection; the end of the fixing rod is fixed with a circular plate; the middle of the circular plate is rotatably connected to a threaded rod; the middle of the threaded rod is threadedly connected to a threaded ring; the side wall of the threaded ring is fixed with a plurality of clamps; the middle of the clamp and the circular plate are in a hinged relationship; the end of the clamp is provided with a slot; by using the clamp to fix the planetary carrier, the stability of the planetary carrier during rotation can be increased, thereby reducing the shaking during rotation, and at the same time, the same operation of the clamp on the threaded rod can make the clamp move synchronously, thereby increasing the fixation of the planetary carrier, thereby reducing the data error caused by the position offset of the planetary carrier during rotation.
[0009] Preferably, a plurality of damping springs are fixed to the bottom of the slot; a slide is fixed to the top of the damping spring; the slide and the slot are slidably connected; by adding the damping spring, the force when the planetary carrier enters the slot can be absorbed, thereby reducing the contact with the probe when falling, and at the same time, the damping spring will press the slide tightly against the planetary carrier so that the slot increases the contact of the slide, thereby increasing the fixation of the splint to the planetary carrier.
[0010] Preferably, a sponge is fixed to the surface of the skateboard; the sponge and the skateboard are arranged correspondingly; by adding the sponge, the friction between the skateboard and the planetary carrier can be increased, so that after the planetary carrier enters the slot, the friction is increased and the position movement is reduced. Since the sponge is flexible, when the splint is buckled inward, the planetary carrier enters the sponge, thereby increasing the contact area between the sponge and the planetary carrier.
[0011] Preferably, a first circular ring is fixedly connected to the middle of the probe; a pair of spring telescopic rods are fixedly connected to the bottom of the first circular ring; the ends of the spring telescopic rods are fixedly connected to the second circular ring; the second circular ring and the end of the probe are fixedly connected; by adding the spring telescopic rod, the end of the probe can rebound quickly after being contacted by the pin shaft, thereby reducing the measurement error caused by the probe and increasing the numerical accuracy of the dial indicator response.
[0012] Preferably, a scraper is fixedly connected to the middle of the spring telescopic rod; the scraper and the end of the spring telescopic rod are correspondingly arranged; by adding the scraper, impurities attached to the end of the spring telescopic rod can be reduced, thereby increasing the smoothness of the spring telescopic rod during operation, so that the probe can rebound to the initial position faster.

By fixing the planetary carrier with a clamping plate, the stability of the planetary carrier during rotation can be increased, thereby reducing shaking during rotation. At the same time, by operating the clamping plates with a threaded rod in the same manner, the clamping plates can be moved synchronously, thereby increasing the fixation of the planetary carrier, thereby reducing data errors caused by position offset during rotation of the planetary carrier.

DETAILED DESCRIPTION
[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] Specific examples are given below.
[0025] like Figures 1 to 5As shown, a gearbox planetary carrier detection device described in an embodiment of the present invention includes a base 1, a first bracket 11 is fixedly connected to the top of the base 1; a motor 16 is fixedly connected to the side wall of the first bracket 11; a bearing seat 17 is installed at the output end of the motor 16; the bearing seat 17 is set through the first bracket 11 and is rotatably connected; a fixing component 12 is installed on the side wall of the bearing seat 17; a second bracket 13 is fixed to the surface of the base 1; a dial indicator 14 is slidably connected to the side wall of the second bracket 13; a probe 15 is installed at the bottom of the dial indicator 14; when working, the planetary carrier is first installed into the inside of the bearing seat 17 and fixed through the fixing component 12, and then the bearing seat 17 and the output end of the motor 16 are connected. At this time, the dial indicator 14 is moved to the planetary By using the bearing seat 17 to fix the planetary carrier and then rotating it to contact the probe 15, the measurement data error of the caliper test can be reduced, thereby increasing the accuracy of the data and making the planetary carrier test faster and increasing the rate of planetary carrier testing.
[0026] like Figure 2 As shown, the fixing assembly 12 includes a plurality of fixing rods 2; the fixing rods 2 and the bearing seat 17 are fixedly connected; the ends of the fixing rods 2 are fixedly connected to a circular plate 21; the middle of the circular plate 21 is rotatably connected to a threaded rod 22; the middle of the threaded rod 22 is threadedly connected to a threaded ring 23; the side walls of the threaded ring 23 are fixedly connected to a plurality of clamping plates 24; the ends of the clamping plates 24 are provided with a card slot 25; when working, when fixing the planetary carrier, first rotate the threaded rod 22 to make the threaded ring 23 close to the circular plate 21, and then put the side wall of the planetary carrier into The clamping plate 24 is used to fix the planetary carrier. The clamping plate 24 is used to fix the planetary carrier. The planetary carrier is locked in the slot 25. The threaded rod 22 is then rotated in the opposite direction to make the threaded ring 23 approach the bearing seat 17. At this time, the clamping plate 24 will shrink inward to buckle the planetary carrier on the circular plate 21, thereby fixing the planetary carrier. By using the clamping plate 24 to fix the planetary carrier, the stability of the planetary carrier during rotation can be increased, thereby reducing the shaking during rotation. At the same time, the same operation of the clamping plate 24 by the threaded rod 22 can make the clamping plate 24 move synchronously, thereby increasing the fixation of the planetary carrier, thereby reducing the data error caused by the position offset when the planetary carrier rotates.
[0027] like Figure 3As shown, a plurality of damping springs 3 are fixed to the bottom of the slot 25; a slide 31 is fixed to the top of the damping spring 3; the slide 31 and the slot 25 are slidably connected; during operation, when the planetary carrier is placed into the slot 25, it will first contact the slide 31, and at this time the damping spring 3 will immediately contract so that the planetary carrier enters the slot 25, and when the splint 24 is buckled inward, the damping spring 3 will continue to contract so that the slide 31 is tightly attached to the planetary carrier, thereby increasing the contact between the slot 25 and the planetary carrier; by adding the damping spring 3, the force of the planetary carrier entering the slot 25 can be absorbed, thereby reducing the contact with the probe 15 when falling, and at the same time, the damping spring 3 will press the slide 31 tightly against the planetary carrier, so that the slot 25 increases the contact of the slide 31, thereby increasing the fixation of the splint 24 to the planetary carrier.
[0028] like Figure 3 As shown, a sponge 4 is fixed to the surface of the slide 31; the sponge 4 and the slide 31 are correspondingly arranged; during operation, when the slide 31 contacts the planetary carrier, the sponge 4 will first contact the planetary carrier to increase the friction therewith, and when the planetary carrier enters the slot 25, the movement of the planetary carrier will be reduced, so that the position of the planetary carrier will be reduced when the splint 24 is buckled inward; by adding the sponge 4, the friction between the slide 31 and the planetary carrier can be increased, so that after the planetary carrier enters the slot 25, the friction is increased and the position movement is reduced. Since the sponge 4 is flexible, the planetary carrier enters the sponge 4 when the splint 24 is buckled inward, thereby increasing the contact area between the sponge 4 and the planetary carrier.
[0029] like Figures 4 and 5 As shown, a first circular ring 5 is fixedly connected to the middle of the probe 15; a pair of spring telescopic rods 51 are fixedly connected to the bottom of the first circular ring 5; the end of the spring telescopic rod 51 is fixedly connected to a second circular ring 52; the second circular ring 52 is fixedly connected to the end of the probe 15; during operation, when the pin contacts the end of the probe 15, the spring telescopic rod 51 will contract, and when the pin leaves the end of the probe 15, the spring telescopic rod 51 will immediately rebound, causing the probe 15 to quickly rebound to its initial position and wait for the next contact of the pin. At the same time, when the difference is calculated among the three pins, since each pin will add the same error, the difference offset during the calculation will not affect the calculation result; by adding the spring telescopic rod 51, the end of the probe 15 can quickly rebound after being contacted by the pin, thereby reducing the measurement error caused by the probe 15 and increasing the numerical accuracy of the dial indicator 14.
[0030] like Figure 5As shown, a scraper 6 is fixedly connected to the middle of the spring telescopic rod 51; the scraper 6 and the end of the spring telescopic rod 51 are correspondingly arranged; during operation, when the spring telescopic rod 51 has been working for a long time, impurities in the air will adhere to the surface of the spring telescopic rod 51, thereby reducing the smoothness of the end of the spring telescopic rod 51 when it is extended and retracted. At this time, the scraper 6 will push off the attached impurities on the surface of the end of the spring telescopic rod 51 when the spring telescopic rod 51 is working; by adding the scraper 6, the impurities attached to the end of the spring telescopic rod 51 can be reduced, thereby increasing the smoothness of the spring telescopic rod 51 when it is working, so that the probe 15 can rebound to the initial position faster.
[0031] Working principle: First, install the planetary carrier into the bearing seat 17 and fix it through the fixing component 12, then connect the bearing seat 17 and the output end of the motor 16. At this time, move the dial indicator 14 to the top of the planetary carrier until the pin on the planetary carrier touches the tip of the probe 15. Then, after fixing the dial indicator 14, start the motor 16 to rotate the bearing seat 17 and drive the planetary carrier to rotate at the same time, so that the three pins will touch the tip of the probe 15 one after another. When the pin touches the probe 15, the dial indicator 14 will show the data of each pin's jump. Record these data and use them. The maximum value minus the minimum value is used to calculate the planet carrier runout value. The smaller the calculated value, the better the accuracy. This is used to detect the accuracy of the planet carrier. When fixing the planet carrier, first rotate the threaded rod 22 to make the threaded ring 23 approach the circular plate 21. At this time, the clamping plate 24 will change its angle and open outward. At this time, put the side wall of the planet carrier into the groove 25. Then rotate the threaded rod 22 in the opposite direction to make the threaded ring 23 approach the bearing seat 17. At this time, the clamping plate 24 will shrink inward to buckle the planet carrier on the circular plate 21, thereby fixing the planet carrier. When the planet carrier is placed in the groove 25, 5 will first contact the slide plate 31, at this time the damping spring 3 will immediately contract so that the planetary carrier enters the slot 25. When the splint 24 buckles inward, the damping spring 3 will continue to contract so that the slide plate 31 is tightly attached to the planetary carrier, thereby increasing the contact between the slot 25 and the planetary carrier. When the slide plate 31 contacts the planetary carrier, the sponge 4 will first contact the planetary carrier to increase friction with it, and when the planetary carrier enters the slot 25, the movement of the planetary carrier will be reduced, thereby reducing the movement of the planetary carrier when the splint 24 buckles inward. When the pin shaft contacts the end of the probe 15, the spring telescopic rod 51 will contract. When the pin shaft contacts the end of the probe 15, the spring telescopic rod 51 will contract. After the axis leaves the end of the probe 15, the spring telescopic rod 51 will rebound immediately, causing the probe 15 to quickly rebound to the initial position and wait for the next contact of the pin shaft. At the same time, when the three pin shafts are calculated for difference, since each pin shaft will add the same error, the difference offset during the calculation will not affect the calculation result; when the spring telescopic rod 51 has been working for a long time, impurities in the air will adhere to the surface of the spring telescopic rod 51, thereby reducing the smoothness of the end of the spring telescopic rod 51 when it is extended and retracted. At this time, the scraper 6 will push off the attached impurities on the surface of the end of the spring telescopic rod 51 when the spring telescopic rod 51 is working.
