Description

Technical Field

[0001] This invention belongs to the field of bearing ring technology, and in particular relates to a bearing ring that is easy to position. Background Technology

[0002] Bearing rings are ring-shaped parts and an important component of rolling bearings. Their main function is to support and guide the rolling elements, ensuring the normal operation and precision of the bearing. They are typically divided into inner and outer rings. Lubricating oil is added inside the bearing rings during use to improve the lubrication of the rolling balls. Special attention must be paid to the installation sequence when installing bearing rings. For precision bearings, the correct orientation must be considered; installing them in reverse will cause dynamic imbalance and affect bearing performance. Because bearing rings have a circular structure, they are very inconvenient to clamp and position during machining. Therefore, it is necessary to improve the bearing ring structure without affecting its performance. Summary of the Invention

[0003] In view of this, the present invention aims to overcome the defects in the prior art and propose a bearing ring that is easy to position.

[0004] To achieve the above objectives, the technical solution created by this invention is implemented as follows:

[0005] A bearing ring for easy positioning includes at least one annular body with an array of positioning structures on both sides. The body has the same number of connecting holes as the positioning structures, arranged radially along the body. Each positioning structure includes symmetrically arranged grooves on both end faces of the body, with the bottom surface of the grooves parallel to the end faces of the body and both side walls perpendicular to the bottom surface of the grooves. A lubricating oil groove is provided on the inner wall of the body between every two sets of positioning structures. The lubricating oil groove includes two intersecting channels that converge at the connecting holes.

[0006] Furthermore, both ends of the lubricating oil groove extend to the corresponding slots.

[0007] Furthermore, the depth of the slot is 0.5-1.5mm.

[0008] Furthermore, the depth of the channel is 0.5-1mm.

[0009] Furthermore, the diameter of the connecting hole is 2-5 mm.

[0010] Furthermore, the connecting hole is centrally located within the body.

[0011] Furthermore, each group of positioning structures is evenly distributed along the circumference of the body.

[0012] Furthermore, it includes two annular bodies, which are fixed together by a connector.

[0013] Compared with existing technologies, the present invention has the following advantages:

[0014] The present invention features a reasonable structural design. By setting positioning structures on both ends of the main body, it facilitates end-face mounting and positioning. By opening connecting holes along the radial direction on the main body, it facilitates circumferential mounting and positioning, which greatly facilitates mounting and positioning during product processing and effectively ensures processing quality.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0022] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this invention. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0023] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] A type of bearing ring that is easy to position, such as Figure 1 and Figure 2 As shown, the device includes at least one annular body 1, with arrays of positioning structures 2 on both sides. The body has the same number of connecting holes 3 as the positioning structures, with one connecting hole between every two positioning structures. The connecting holes are arranged radially along the body. The positioning structures include slots 4 symmetrically arranged on both end faces of the body. ， The bottom surface 5 of the groove is parallel to the end face 6 of the body. ， Both sides 7 of the slot are perpendicular to the bottom surface of the slot; the bearing ring provided by the present invention can be used as the inner ring of the bearing. A set of lubricating oil grooves is provided between every two sets of positioning structures on the inner wall of the main body. The lubricating oil grooves include two cross-arranged channels 10, and the two channels of each set of lubricating oil grooves converge at the connecting hole.

[0026] When the bearing ring provided by this invention comprises two or more bodies, the bodies are fixed together by a connecting member 8. For example, Figures 3 to 5 As shown, the bearing race includes two annular bodies. A connector is provided for each set of positioning structures. The connector is a screw that passes through the two bodies and is locked by a nut. A countersunk platform 9 is provided on the bottom surface of the slot on the outer end face of the two bodies. The nut and the nut part of the screw are both submerged in the countersunk platform of the corresponding slot. The connector does not hinder the mounting and positioning function of the slot.

[0027] When machining bearing rings, the retaining grooves can be used for mounting and positioning the bearing rings at both ends, while the connecting holes of the bearing rings can be used for mounting and positioning the outer circumferential surface. This greatly facilitates the machining of the bearing rings and also makes subsequent bearing assembly easier. The lubricating oil groove extends to its corresponding retaining groove at both ends. When lubricating oil is added to the outside of the bearing rings, the lubricating oil is allowed to flow through the connecting holes to the inner wall of the bearing housing. When lubricating oil is added to the inside of the bearing rings, the lubricating oil is allowed to flow through the connecting holes to the outer wall of the bearing housing. The lubricating oil groove guides the flow of lubricating oil, improving the lubrication effect of the bearing.

[0028] Preferably, each group of positioning structures is evenly distributed along the circumference of the body. The depth of the slot is 0.5-1.5mm. The depth of the channel is 0.5-1mm. The diameter of the connecting hole is 2-5mm. The connecting hole is centrally located on the body.

[0029] The present invention features a reasonable structural design. By setting positioning structures on both ends of the main body, it facilitates end-face mounting and positioning. By opening connecting holes along the radial direction on the main body, it facilitates circumferential mounting and positioning, which greatly facilitates mounting and positioning during product processing and effectively ensures processing quality.

[0030] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
