Description

Technical Field

[0001] This utility model relates to the field of bearing cage technology, and in particular to a cage for enhancing the stability of tapered roller bearings. Background Technology

[0002] A bearing cage (also known as a bearing retainer) is a component in a rolling bearing used to isolate the rolling elements, guide their movement, and prevent them from falling out. It is usually made of elastic materials (such as nylon, steel, etc.) and achieves dynamic isolation by encasing part or all of the rolling elements.

[0003] Typically, the rolling elements on a cage are directly fitted into the bores in the cage. During use, the inner wall of the cage bores and the sidewall of the rolling elements are always in contact, increasing the frictional area between the rolling elements and the cage. This results in relatively high frictional resistance during the rotation of the rolling elements, making their rotation less flexible. Therefore, how to make the rolling elements rotate more flexibly and enhance the stability of the bearing is an important problem that needs to be solved in the cage design to enhance the stability of tapered roller bearings. Utility Model Content

[0004] To address the problem of relatively high frictional resistance during the rotation of rolling elements, which makes the rotation of rolling elements less flexible, this invention provides a cage that enhances the stability of tapered rollers.

[0005] This utility model solves the above-mentioned technical problems through the following technical solutions: A cage for enhancing the stability of tapered rollers includes a cage and tapered rollers. The cage has a tapered tube structure with multiple trapezoidal holes evenly spaced around its sidewalls. Tapered rollers, matching the number of trapezoidal holes, are placed inside the trapezoidal holes. A stabilizing retaining structure is provided between the two ends of each tapered roller and the two ends of each trapezoidal hole. The stabilizing retaining structure includes a support block. An "L"-shaped locking bracket is provided at one end of the support block. Multiple hemispherical recesses are spaced around the center of the other end of the support block. "L"-shaped insertion grooves are provided opposite each other on the sidewalls at both ends of each trapezoidal hole. The "L"-shaped locking bracket is engaged in the "L"-shaped insertion groove. Rotating balls are provided in each of the multiple hemispherical recesses. The end of the rotating ball located outside the hemispherical recess contacts the end of the tapered roller. A lubrication structure is provided in each support block.

[0006] The cage for enhancing the stability of tapered rollers has a retaining block at the center of the end face at the other end of the support block, and a retaining groove at both ends of each tapered roller, with the retaining block located in the groove.

[0007] The cage for enhancing the stability of tapered rollers has blind holes at the end faces of both ends of the cage and at the corresponding positions of the "L"-shaped insertion slots. There are through holes between the blind holes and the corresponding "L"-shaped insertion slots. There are screw holes on the "L"-shaped snap-fit ​​bracket. The fixing bolt passes through the through hole and is screwed into the screw hole. The screw head of the fixing bolt is located in the blind hole.

[0008] The cage for enhancing the stability of tapered rollers has a lubrication structure including a lubricating oil cavity located within a support block. Through holes are provided between the lubricating oil cavity and the bottom of multiple hemispherical sockets, and a cotton pad is provided in each through hole.

[0009] The cage for enhancing the stability of the tapered rollers has an oil-absorbing cotton rope inside the lubrication chamber, with one end of the oil-absorbing cotton rope fixedly connected to the coating cotton block.

[0010] The cage for enhancing the stability of tapered rollers has an oil injection hole on the side wall of the lubrication chamber that extends through the outside of the support block, and a sealing cap is provided on the oil injection hole.

[0011] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0012] The positive and progressive effects of this utility model are as follows: 1. Secure the "L"-shaped retaining bracket with fixing bolts. Then, secure the support blocks to the "L"-shaped retaining bracket. Fix the two support blocks to the two ends of the trapezoidal hole respectively. The retaining blocks on the two support blocks engage in the retaining grooves, which stably hold the tapered roller in the trapezoidal hole without contacting the inner wall of the trapezoidal hole. This reduces the frictional resistance between the tapered roller and the retainer. The rotating ball presses against the side wall of the tapered roller. While the retaining blocks help hold the tapered roller, the rotating roller can rotate synchronously when the tapered roller rotates, reducing rotational resistance and making the tapered roller rotate more flexibly, thereby enhancing the stability of the bearing. 2. The oil-absorbing cotton rope absorbs the lubricating oil and transfers it to the application cotton block. The application cotton block absorbs the lubricating oil, and as the rotating ball rotates, the lubricating oil is applied to the side wall of the rotating ball, which makes the rotation of the ball smoother and further reduces frictional resistance.

The other end face of the retainer 1 has multiple hemispherical sockets 805 spaced around its center. On the side walls at both ends of each trapezoidal hole 2, there are L-shaped insertion slots 3. An L-shaped locking bracket 804 is engaged within the L-shaped insertion slot 3. Blind holes 7 are provided at the corresponding positions on the end faces of both ends of the retainer 1 and the L-shaped insertion slots 3. Through holes 701 are provided between the blind holes 7 and the corresponding L-shaped insertion slots 3. Screw holes 806 are provided on the L-shaped locking bracket 804, through which fixing bolts 6 pass. 01 is screwed into screw hole 806. The screw head of fixing bolt 6 is located in blind hole 7. Rotating ball 803 is provided in multiple hemispherical sockets 805. The end of rotating ball 803 located outside hemispherical socket 805 contacts the end of tapered roller 4. A retaining block 802 is provided in the middle of the end face of the other end of support block 801. A retaining block 802 is provided in the grooves 5 at both ends of each tapered roller 4. The retaining block 802 is located in the grooves 5. A lubrication structure 9 is provided in each support block 801. The lubrication structure 9 includes lubricating... The lubricating oil cavity 901 is located inside the support block 801. A through hole 904 is provided between the lubricating oil cavity 901 and the bottom of the multiple hemispherical sockets 805. A cotton pad 902 is provided in each through hole 904. An oil-absorbing cotton rope 903 is provided in the lubricating oil cavity 901.

An oil injection hole 911 is provided on the side wall of the lubricating oil cavity 901, which penetrates the outside of the support block 801. A sealing cap 912 is provided on the oil injection hole 911.

[0017] To implement the cage for enhancing the stability of tapered rollers as described in this utility model, when installing the tapered roller 4, the two support blocks 801 are respectively held in place by their retaining blocks 802 against the slots 5 at both ends of the tapered roller 4, so that the rotating balls 803 on the two support blocks 801 abut against both ends of the tapered roller 4. The two support blocks 801 holding the tapered roller 4 are respectively held in place by their "L"-shaped clamping brackets 804 into the "L"-shaped insertion slots 3 at both ends of the trapezoidal hole 2. The fixing bolt 6 passes through the through hole 701 and is screwed into the screw hole 806. The screw head of the fixing bolt 6 is located in the blind hole 7. The tapered roller 4 is then installed in place. The roller 4 is confined within the trapezoidal hole 2. This allows the retaining blocks 802 on the two support blocks 801 to stably hold the tapered roller 4 within the trapezoidal hole 2 without contacting the inner wall of the trapezoidal hole 2. This reduces the frictional resistance between the tapered roller 4 and the cage 1. The rotating balls 803 abut against both ends of the tapered roller 4, assisting the retaining blocks 802 in holding the tapered roller 4. At the same time, the rotating balls 803 can rotate synchronously when the tapered roller 4 rotates, reducing rotational resistance and making the tapered roller 4 rotate more flexibly, thereby enhancing the stability of the bearing. The tapered roller 4 is arranged in multiple trapezoidal holes 2 according to the above steps. Lubricating oil is injected into the lubricating oil cavity 901 through the oil injection hole 911. After the lubricating oil is injected, the sealing cap 912 is used to seal the oil injection hole 911. The oil-absorbing cotton rope 903 absorbs the lubricating oil and transfers it to the applicator cotton block 902. The applicator cotton block 902 absorbs the lubricating oil and, as the rotating ball 803 rotates, applies the lubricating oil to the side wall of the rotating ball 803, making the rotation of the rotating ball 803 smoother and further reducing frictional resistance.
