Description

[0001] The invention relates to control and measuring equipment, in particular to methods for monitoring the quality of the assembly of a gear transmission of a rotary support device, and can find its application for checking rotary support devices installed in road construction and other mobile equipment.

[0002] A method for testing a port davit support and rotating device is known from the prior art [patent JPS6088346A, IPC G01M99 / 00, published on May 18, 1985], in which the davit is temporarily held in a horizontal position, then tilted to a predetermined vertical tilt angle, wherein the predetermined rotation angle is imparted to the tilt of the tilt axis, and a predetermined compound tilt angle is formed. Then, the port davit, held at a predetermined tilt angle, is moved horizontally in a predetermined tilt direction. The lower frame of the support and rotating device rotates horizontally on the base, and a vertically controlled intermediate frame is supported on a support post attached to the lower frame, and the upper base is pivotally mounted on the intermediate frame.

[0003] The disadvantages of this method of testing a rotary support device are the lack of quality control of the assembly of the gear transmission of the rotary support device in terms of measuring the radial and (or) lateral clearance of the gear transmission of the rotary support device when it is tilted and at different relative positions of its elements, as well as the high labor intensity when reinstalling the rotary support devices.

[0004] Also, from the prior art, a method is known for creating combinations of roll-trim positions of a heavy product having a tracked or wheeled drive [RU 2809962, IPC G01M 17 / 007 G01M 1 / 00, published 12 / 19 / 2023, Bull. No. 35], which includes locking the turntable of the stand from rotation using a locking device against rotation, fixing the turntable from tilting using stops, ensuring that the side locks of the product are in the retracted position, moving the product onto the stand, fixing the product from movement by fastening it with side locks, after which the turntable is unlocked from tilting using stops, then the turntable of the stand is unlocked for rotation, then the turntable with the product installed and secured on it is rotated to an angle slightly less than that required in high-speed mode, then the turntable together with the product is rotated to the required angle in low-speed mode,then the turntable of the stand is locked from rotation, the product is tilted to an angle slightly less than that required in high-speed mode, then the inclined frame together with the turntable and the product fixed on it is tilted to the required angle in low-speed mode, the lifting frame is fixed in a given position using the braking mechanisms built into the tilt drive, then the necessary parameters of the product, which has received the required roll-trim position on the turntable fixed on the inclined frame, are checked, then the inclined frame and the turntable with the product are returned to the horizontal position using the tilt drive, the turntable of the stand is unlocked for rotation, the platform with the product is turned to its original position, the turntable of the turntable is locked, the product is unlocked from movement using the side locks,fix the turning platform from tilting using stops, move the product from the stand,

[0005] The disadvantage of this method is the lack of ability to control the quality of the assembly of the gear transmission of the rotary support device in terms of measuring the radial and (or) lateral clearance of the gear transmission of the rotary support device when it is tilted and in various relative positions of its elements, since the tilt of the product being tested is carried out only in one direction, and the product being tested itself must have a tracked or wheeled drive.

[0006] In addition, a method for assembling and running-in a bearing run is known from the prior art [RU 2249192, IPC G01M 19 / 00, published 03 / 27 / 2005 Bulletin No. 9], which includes assembling the run, loading it with an equally distributed axial load, checking the axial play and radial runout, wherein before checking the radial runout, the axial load is formed to the actual mass by an additional load, the center of gravity of which is oriented according to a given value of deviation of the center of gravity of the actual mass.

[0007] The disadvantages of this method of assembling and running in a bearing run are the lack of the ability to tilt the run to the minimum and maximum operating angles at different relative positions of its elements and, accordingly, the lack of the ability to control the quality of the assembly of the run gear under conditions close to operating conditions with high reliability of this process.

[0008] This technical solution is adopted as a prototype for the claimed methods of quality control of the assembly of the gear transmission of the rotary support device.

[0009] The problem, which the claimed technical solution is aimed at solving, is the creation of methods for quality control of the assembly of the gear transmission of the rotary support device, which make it possible to ensure the measurement of the radial and / or lateral clearance of the gear transmission of the rotary support device under conditions close to operational conditions with a high reliability of this process.

[0010] The technical result of using the claimed methods for quality control of the assembly of a gear transmission of a rotary support device consists in increasing the reliability of the process of quality control of the assembly of a gear transmission of a rotary support device by carrying out quality control of its assembly at minimum and maximum values ​​of operating angles at various relative positions of its elements.

[0011] The problem is solved, and the technical result set for the first option is achieved by the fact that the method for quality control of the assembly of the gear transmission of the rotary support device includes stages at which

[0016] fix the fixed ring of the slewing ring,

[0017] tilt the rotary support device relative to the X axis of the stand to a spatial position in which the driving gear of the rotary support device is located in the upper spatial position corresponding to the maximum value of the operating angle α,

[0018] measure the radial and / or lateral clearances of the gear engagement between the drive gear of the slewing bearing and the ring gear of the slewing bearing,

[0019] rotate the movable ring of the rotary support device around its vertical axis at angles of 90°, 180° and 270° and measure the radial and / or lateral clearance of the gear engagement between the driving gear of the rotary support device and the gear ring of the rotary support device after each rotation of the movable ring of the rotary support device around the axis.

[0020] The problem is solved, and the technical result set for the second option is achieved by the fact that the method for quality control of the assembly of the gear transmission of the rotary support device includes stages at which

[0021] install the rotary support device on the support plate of the stand, which is designed with the possibility of tilting and fixing its position relative to the X-axis of the stand,

[0022] connect the fixed ring of the rotary support device with the drive of the driving gear, ensuring the engagement of the driving gear of the fixed ring of the rotary support device with the toothed rim of the movable ring of the rotary support device,

[0023] load the slewing ring with axial load,

[0024] rotate the fixed ring of the rotary support device, connected to the drive of the driving gear, around the vertical Z axis of the stand to a spatial position in which the axis of rotation of the driving gear coincides with the plane of symmetry passing through the Y axis of the stand,

[0025] fix the fixed ring of the slewing ring,

[0029] measure the radial and / or lateral clearances of the gear engagement between the drive gear of the slewing bearing and the ring gear of the slewing bearing,

[0030] Set the slewing ring to a horizontal position,

[0031] sequentially rotate the movable ring of the rotary support device around its vertical axis at angles of 90°, 180° and 270° and tilt the rotary support device relative to the X axis of the stand at the maximum and minimum value of the operating angle α and measure the radial and / or lateral clearance of the gear engagement between the driving gear of the rotary support device and the gear ring of the rotary support device after each rotation of the movable ring of the rotary support device around the axis.
