Abstract
Description
Technical Field
[0001] This application relates to the field of slewing bearing transmission technology, specifically to an installation and adjustment structure for a slewing bearing motor. Background Technology
[0002] Gear-type slewing bearings are special large bearings capable of simultaneously withstanding axial force, radial force, and overturning moment. They typically consist of an inner ring, an outer ring, and rolling elements. The inner or outer ring has machined toothed structures for meshing with a motor gear. Currently, the mainstream drive method involves a motor driving a pinion to rotate, causing it to mesh tightly with the slewing bearing's gear ring, thus transmitting power. However, under heavy-load transmission conditions, if the meshing clearance between the pinion on the motor output shaft and the external gear of the slewing bearing is too small, the motor output shaft will bear a large eccentric load, leading to output shaft deformation, excessive gear wear and seizing, and even deformation and cracking of the reducer housing, ultimately severely affecting the operational stability of the equipment. Therefore, during operation, it is necessary to pay close attention to the meshing clearance between the pinion on the motor output shaft and the external teeth of the slewing bearing. If the meshing clearance is too small, it needs to be adjusted in time to avoid deformation of the output bearing due to excessive eccentric load. The usual adjustment method is to manually move the motor to change the position of the motor output shaft, thereby achieving the meshing clearance between the pinion on the motor output shaft and the external teeth of the slewing bearing. Since the motor has a certain weight, the manual moving method has the problem of difficulty in accurately positioning the motor, requiring repeated moving, which is time-consuming and labor-intensive. Alternatively, automated fixtures and automated motion devices can be used to achieve precise positioning of the motor. This method requires moving the automated fixtures and automated motion devices back and forth, which is inconvenient to implement. In some installation situations, the operating space near the motor is small, and the automated fixtures and automated motion devices cannot complete the operation. Utility Model Content

Detailed Implementation
[0018] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this application are only for explaining this application and are not intended to limit this application.
[0019] like Figures 1-5As shown in the figure, this application provides an installation and adjustment structure for a slewing bearing motor. The structure includes a support base 301, a motor mounting plate 102, a bearing mounting plate, a first adjustment base 103, and a second adjustment base 212. The support base 301 is a plate structure, with its two surfaces serving as a first mounting surface and a second mounting surface, respectively. A sliding groove, rectangular in shape, extends through the support base 301 to form a notch. The motor mounting plate 102 is located within the sliding groove and connected to the sliding groove of the support base 301. The motor mounting plate 102 is rectangular, and its width is approximately equal to the width of the sliding groove, meaning that when the motor mounting plate 102 is within the sliding groove, it can only slide in one direction. For example, it can slide back and forth towards or away from the notch. A first clearance hole is provided on the motor mounting plate 102 for... The output shaft of motor 101 is provided with a clearance; the bearing mounting plate is connected to the second mounting surface via a groove, and the bearing mounting plate has a second clearance hole for clearance of bearing 206. The second clearance hole is typically adapted to the outer diameter of bearing 206; the first adjusting base 103 is connected to the first mounting surface, and a first adjusting rod that abuts against motor mounting plate 102 is movably connected to the first adjusting base 103, meaning that when the first adjusting rod moves on the first adjusting base 103, it can change the position of motor mounting plate 102 in at least one direction; the second adjusting base 212 is connected to the second mounting surface, and a second adjusting rod that abuts against bearing mounting plate is movably connected to the second adjusting base 212, meaning that when the second adjusting rod moves on the second base, it can change the position of bearing mounting plate in at least one direction; bearing 206 and the output shaft of motor 101 are coaxially fitted, therefore the first adjusting rod and the second adjusting rod move motor mounting plate 102 and bearing mounting plate in the same direction, for example, from the notch inward.
[0020] When adjusting the position of the output shaft of motor 101, loosen the fastening connection between motor mounting plate 102, bearing mounting plate, and support base 301. Since motor mounting plate 102 and bearing mounting plate are all connected to support base 301 via sliding grooves, motor mounting plate 102 and bearing mounting plate are movable relative to support base 301. This means that motor mounting plate 102 can move towards or away from the notch. Here, the direction of motor mounting plate 102 towards the notch is defined as the first direction, and the direction of motor mounting plate 102 away from the notch is defined as the second direction. This allows the first adjusting rod and the second adjusting rod to disengage from motor mounting plate 101. 2. With the bearing mounting plate, manually change the position of the motor 101 to drive the motor mounting plate 102 to move in the first direction, completing the coarse positioning of the motor 101. Make the first adjusting rod abut against the motor mounting plate 102 and drive the first adjusting rod to move on the first adjusting base 103 to drive the motor mounting plate 102 to move in the second direction, completing the accurate positioning of the motor 101. Make the second adjusting rod abut against the bearing mounting plate and apply a small contact pressure to achieve the rotation limit of the bearing mounting plate. Tightly connect the motor mounting plate 102 and the support base 301, and the bearing mounting plate and the support base 301 respectively, to complete the position adjustment of the output shaft of the motor 101.
[0021] The installation and adjustment structure for a slewing bearing motor provided in this application is installed together with the motor 101. The adjustment is performed directly on-site without the need to access other resources such as automated fixtures or automated motion devices. At the same time, the operating space requirement is only the operating space required for the installation of the motor 101, without the need for additional movement clearance space. During adjustment, the motor 101 is coarsely positioned manually, and then the output shaft of the motor 101 and the bearing 206 of the motor 101 are accurately positioned simultaneously by the first adjusting rod on the first adjusting base 103 and the second adjusting rod on the second adjusting base 212. This solves the problem of difficult positioning caused by manual handling in existing systems.
[0022] In this embodiment of the application, a groove connection refers to a connection in which at least one of the two components has a bolt hole that is a slot hole. After the two components are connected by bolts, one component can slide relative to the other component before the bolts are tightened. This is a common connection method in the mechanical field. For example, in this embodiment of the application, a number of slot holes are opened on the motor mounting plate 102, and the motor mounting plate 102 forms a groove connection with the support base 301 through the first bolt 104.
[0023] In this embodiment, the motor mounting plate 102 has a plurality of connecting holes evenly distributed around the circumference of the first clearance hole, and the connecting holes are fastened to the motor 101 by the second bolt 105.
[0024] In this embodiment, the gear 205 on the motor 101 engages with the output shaft hole of the motor 101. The end of the output shaft of the motor 101 is connected to an end plate 204 by a seventh bolt 201 to axially position the gear 205. The gear 205 meshes with the external teeth on the slewing bearing 302 to achieve transmission. A bushing 202 is fitted on the output shaft of the motor 101 to isolate the output shaft of the motor 101 from the support base 301. The bushing 202 is axially limited by a snap ring 203. A bearing 206 is fitted between the bushing 202 and the support base 301 to ensure smooth rotation.
[0025] In some optional embodiments, the first adjusting base 103 includes a first fixed base and a second fixed base; the first fixed base is fixedly connected to the support base 301; the second fixed base is fixedly connected to the support base 301, and the second fixed base and the first fixed base are arranged at intervals. In actual implementation, the first fixed base and the second fixed base can be connected at both ends in the width direction of the notch of the sliding groove.
[0026] In this embodiment, the first adjusting base 103 and the second adjusting base 212 are subjected to force independently, which is less prone to deformation compared to multiple points of force on the same base.
[0027] In some optional embodiments, the first fixed seat and / or the second fixed seat are bolted to the support base 301. In actual implementation, both the first fixed seat and the second fixed seat can be fixedly connected to the support base 301 by the third bolt 107. The first fixed seat and the second fixed seat are respectively connected to the support base 301 by two third bolts 107 to ensure connection stability and ensure the positioning accuracy of the first fixed seat and the second fixed seat after connection.
[0028] In some optional embodiments, the first adjusting rod passes through the first adjusting base 103 and is threadedly engaged with the first adjusting base 103; in actual implementation, the first adjusting rod can be set as a fourth bolt 106, the length direction of the fourth bolt 106 is parallel to the movable direction of the motor mounting plate 102 in the sliding groove, by rotating the fourth bolt 106, the end of the fourth bolt 106 can contact the motor mounting plate 102 and push the motor mounting plate 102 to move in the sliding groove.
[0029] In some optional embodiments, the second adjusting base 212 is welded to the second mounting surface by stiffening plates, thereby ensuring the connection stability between the second adjusting base 212 and the support base 301. In actual implementation, the number of stiffening plates is not less than 4, and the 4 stiffening plates are arranged at equal intervals to ensure balanced force.
[0030] In some optional embodiments, the second adjusting rod passes through the second adjusting base 212 and is threaded into the second adjusting base 212; in actual implementation, the second adjusting rod can be set as the fifth bolt 211. By rotating the fifth bolt 211, the end of the fifth bolt 211 can contact the bearing mounting plate. The bearing mounting plate is a rectangular plate in general. After the two fifth bolts 211 contact one side of the bearing mounting plate at the same time, the bearing mounting plate can be rotated and limited.
[0031] In some optional embodiments, the bearing mounting plate includes a first splicing plate 207, a second splicing plate 208, and a dustproof plate 210. A first arc-shaped notch is provided on one side of the first splicing plate 207; a second arc-shaped notch is provided on one side of the second splicing plate 208. The first arc-shaped notch can be spliced with the second arc-shaped notch to form a mating circular hole adapted to the bearing 206, meaning that both the first and second arc-shaped notches are semi-circular notches. The dustproof plate 210 can be connected to the first splicing plate 207 and the second splicing plate 208 via a sixth bolt 209, meaning that the first splicing plate 207 and the second splicing plate 208 are connected as a whole by the dustproof plate 210. The dustproof plate 210 has a motor 101 shaft clearance hole, the diameter of which is smaller than the diameter of the mating circular hole. Therefore, the dustproof plate 210 can cover the bearing 206 in the axial direction of the mating circular hole, preventing excessive dust from entering the bearing 206.
[0032] In some optional embodiments, the motor mounting plate 102 and the bearing mounting plate share one or a set of bolts connected to the sliding groove of the support base 301. This means that the motor mounting plate 102 and the bearing mounting plate each have corresponding slots. The first bolt 104 passes through the slots on the motor mounting plate, the support base 301, and the bearing mounting plate in sequence, and is finally locked with a nut. In this way, after the motor mounting plate 102 is adjusted into place by the first adjusting rod and the bearing mounting plate is limited by the second adjusting rod, the motor mounting plate 102 and the bearing mounting plate can be fixed simultaneously by the first bolt 104, which is time-saving and convenient.
