Description

Technical field:

[0001] The invention relates to the technical field of bearing production, in particular to a method for installing a plastic retainer on a double-row bearing. Background technology:

[0002] Rolling bearings are often installed in various precision machines to perform high-precision movements. Rolling bearings typically consist of an outer ring, an inner ring, rolling elements, and a retainer. The rolling elements are positioned between the inner and outer rings, while the retainer confines the rolling elements within the grooves of the inner and outer rings of the rolling bearing and maintains an appropriate distance between adjacent rolling elements.

[0003] For machinery requiring high rotational speeds, the rolling bearings used are typically equipped with a plastic retainer. Due to their lightweight and wear-resistant properties, plastic retainers enable rolling bearings to withstand high speeds and low torques. However, for double-row ball bearings with a non-full ball structure, manual work is required to evenly arrange the double-row steel balls within the bearing's rolling area before placing the retainer. This results in low efficiency and a waste of labor. Summary of the invention:

[0004] An object of the present invention is to provide a method for installing a plastic retainer on a double-row bearing, so as to solve one or more of the above-mentioned problems in the prior art.

[0005] In order to solve the above technical problems, the innovation of the present invention is that it specifically includes the following steps:

[0006] S1. Set a rotatable tray on the workbench and clamp the bearing ring inside the tray;

[0007] S2. Place the steel balls one by one into the rolling area of ​​the bearing ring, and then extend the setting needle into the rolling area of ​​the bearing ring;

[0008] S3. Rotate the tray so that the pins move the steel balls in the rolling area of ​​the bearing ring, and the moved steel balls are finally evenly arranged in the rolling area of ​​the bearing ring;

[0009] S4. Install the plastic retainer on the rolling area of ​​the bearing ring, and finally press the plastic retainer against the rolling area of ​​the bearing ring;

[0010] In step S3, the tray is first rotated 180° clockwise and then 180° counterclockwise, so that the steel ball rotates in the positive and negative directions in the rolling area of ​​the bearing ring.

[0011] Furthermore, a dividing plate is provided at the bottom of the workbench, the dividing plate and the tray rotate coaxially, and a driving member for driving the dividing plate to rotate is provided on the workbench.

[0012] Furthermore, the above-mentioned driving component includes a rotating motor and several external gears. A sleeve extends downward from the center position of the bottom of the dividing plate, and several internal gears are distributed inside the sleeve from top to bottom. A driving rod extends upward from the output end of the rotating motor, and the driving rod extends inside the sleeve. Several external gears are distributed on the driving rod from top to bottom, and the external gears and the internal gears are meshed and connected.

[0013] Furthermore, a rotating shaft is connected between the indexing plate and the tray, an encoder is provided at the center of the rotating shaft, a controller is provided on the rotating motor, and the controller and the encoder are electrically connected.

[0014] Furthermore, a circular ring is provided at the bottom of the setting needle, and the diameter of the ring is smaller than the diameter of the steel ball.

[0015] The beneficial effects of the present invention are:

[0016] 1. The present invention provides a method for installing a plastic retainer on a double-row bearing. After placing a steel ball in the rolling area of ​​the bearing ring, the steel ball is moved so that the steel ball can be quickly spread in the rolling area of ​​the bearing ring. In addition, during the rolling process of the steel ball, the steel ball rolls 180° in the forward direction and 180° in the reverse direction, so that the steel ball rolls in position information in different directions, thereby preventing the steel balls from being accumulated and arranged in a certain direction of the rolling area, ensuring the uniform arrangement of the steel balls in the rolling area, and improving the installation efficiency of the plastic retainer.

[0017] 2. The present invention provides a method for installing a plastic retainer on a double-row bearing. The rotating motor is turned on, and the rotating motor drives the driving rod to rotate. Under the meshing action of the external gear and the internal gear, the sleeve is driven to rotate, thereby rotating the electric sleeve to realize the rotation of the dividing plate. The meshing action of the internal gear and the external gear ensures that the rotation of the dividing plate remains stable.

[0018] 3. The present invention provides a method for installing a plastic retainer on a double-row bearing, wherein the ferrule can half-hoop the steel ball, ensuring that the steel ball can be pushed as a whole when the steel ball is moved to roll, thereby avoiding the steel ball from slipping during the movement, thereby maintaining a stable movement of the steel ball.

[0020] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0021] like Figure 1A specific embodiment of the present invention includes the following steps:

[0022] S1. A rotatable tray 11 is set on a workbench 1, and a bearing ring is clamped inside the tray 11;

[0023] S2. Place the steel balls one by one into the rolling area of ​​the bearing ring, and then extend the setting needle 2 into the rolling area of ​​the bearing ring;

[0024] S3, rotating the tray 11 so that the setting needle 2 moves the steel balls in the rolling area of ​​the bearing ring, and the moved steel balls are finally evenly arranged in the rolling area of ​​the bearing ring;

[0025] S4. Install the plastic retainer on the rolling area of ​​the bearing ring, and finally press the plastic retainer against the rolling area of ​​the bearing ring;

[0026] In step S3 , the tray 11 is first rotated 180° clockwise and then 180° counterclockwise, so that the steel balls rotate in the rolling area of ​​the bearing ring in the forward and reverse directions.

[0027] In the present invention, after the steel ball is placed in the rolling area of ​​the bearing ring, the steel ball is moved so that the steel ball can be quickly spread in the rolling area of ​​the bearing ring. In addition, during the rolling process of the steel ball, the steel ball rolls 180° in the forward direction and 180° in the reverse direction, so that the position information of the steel ball rolls in different directions, thereby avoiding the steel balls from being accumulated and arranged in a local area in a certain direction of the rolling area, ensuring the uniform arrangement of the steel balls in the rolling area, and improving the installation efficiency of the plastic retainer.

[0028] In the present invention, as a preferred solution, a dividing plate 3 is provided at the bottom of the workbench 1 , and the dividing plate 3 and the tray 11 rotate coaxially. A driving member 4 for driving the dividing plate 3 to rotate is provided on the workbench 1 .

[0029] In the present invention, the setting of the indexing plate 3 plays a role in positioning the rotational position of the tray 11, ensuring that the tray 11 can rotate 180° in the forward and reverse directions.

[0030] In the present invention, as a preferred embodiment, the driving member 4 includes a rotating motor 41 and a plurality of external gears 42. A sleeve 5 extends downward from the center of the bottom of the dividing plate 3. A plurality of internal gears 51 are distributed from top to bottom inside the sleeve 5. A driving rod 52 extends upward from the output end of the rotating motor 41. The driving rod 52 extends inside the sleeve 5. A plurality of external gears 42 are distributed on the driving rod 52 from top to bottom. The external gears 42 and the internal gears 51 are meshed and connected.

[0031] In the present invention, the working principle of the driving member 4 driving the indexing plate 3 to rotate is as follows: the rotating motor 41 is turned on, and the rotating motor 41 drives the driving rod 52 to rotate, and under the meshing action of the outer gear 42 and the inner gear 51, the sleeve 5 is driven to rotate, so that the electric sleeve 5 is rotated to realize the rotation of the indexing plate 3, and the meshing action of the inner gear 51 and the outer gear 42 ensures that the rotation of the indexing plate 3 remains stable.

[0032] In the present invention, as a preferred solution, a rotating shaft 6 is connected between the indexing plate 3 and the tray 11 , an encoder 61 is provided at the center of the rotating shaft 6 , a controller is provided on the rotating motor 41 , and the controller and the encoder 61 are electrically connected.

[0033] In the present invention, the dividing plate 3 drives the tray 11 to rotate through the rotating shaft 6. The encoder 61 is set on the rotating shaft 6 and can monitor the rotation speed of the rotating shaft 6. The rotation speed of the rotating motor 41 is controlled by the controller, so that the rotation speed of the tray 11 can be adjusted, thereby avoiding the tray 11 rotating too fast, causing the steel ball to roll out of the rolling area.

[0034] In the present invention, as a preferred solution, a circular ring 62 is provided at the bottom of the setting needle 2 , and the diameter of the ring 62 is smaller than the diameter of the steel ball.

[0035] In the present invention, the ferrule 62 can half-hoop the steel ball, ensuring that the steel ball can be pushed as a whole when the steel ball is moved to roll, thereby avoiding the steel ball from slipping during the movement, thereby keeping the movement of the steel ball stable.
