Description

TECHNICAL FIELD

[0001] The utility model relates to engineering parts technical field, concretely relates to a novel check ring. BACKGROUND

[0002] The check ring is a mechanical fixing part, mainly used for fixing the position of bearing, shaft and other mechanical parts, preventing swing, deviation and other problems during operation or use. The check ring plays an important role in automobiles and other mechanical equipment, ensuring the stability of each part during operation. The traditional check ring is basically in the form of an open ring. Due to the existence of the opening, the space available for deformation of the traditional check ring in the opening and closing direction is very small. If the opening is slightly expanded, it cannot be used continuously, which severely limits the service life of the traditional check ring. SUMMARY

[0003] In order to solve the technical problems existing in the background art, the utility model provides a novel check ring.

[0004] The utility model provides a novel check ring, the check ring is closed ring with the end face of the head end and the tail end mutually adhering in the natural state.

[0005] Preferably, the head end and the tail end of the check ring are formed by cutting off the circular ring.

[0006] Preferably, the head end and the tail end of the check ring are located in the same plane.

[0007] Preferably, the width of the end where the head end is located and the end where the tail end is located is greater than the width of other parts of the check ring.

[0008] Preferably, the head end and the tail end of the check ring are located in the same plane.

[0009] Preferably, the check ring includes a left side ring body from the head end to the bisector and a right side ring body from the tail end to the bisector, and the width of the left side ring body and the right side ring body decreases successively from the bisector to the end.

[0010] In the utility model, the check ring is designed as a closed ring structure with the head end and the tail end mutually adhering in the natural state. This structure design changes the traditional open check ring structure design, so that there is no gap in the circumferential direction of the check ring, which increases the contact area between the check ring and the groove on the part after the check ring is assembled on the part, and improves the limit speed capacity. In addition, compared with the traditional open check ring structure, the check ring can allow a larger change in the opening degree, which can effectively improve the service life of the check ring and improve the processing efficiency. BRIEF DESCRIPTION OF DRAWINGS

[0011] Figure 1A structure diagram of a novel check ring is provided in the utility model. DETAILED DESCRIPTION

[0012] REFERENCE Figure 1 The utility model provides a novel check ring, the check ring is formed first end 1 and tail end 2 via cutting knife cutting, and the first end 1 of check ring and its tail end 2 are located in the same plane, and the end face of the first end 1 and the tail end 2 of check ring mutually abuts in natural state to form closed ring, and the specific processing mode is as follows:

[0013] First, a circular ring is processed on the base material, and then the circular ring is cut off by using cutting equipment to form a fracture surface on both sides of the fracture, one side of the fracture surface constitutes the first end 1 end surface of the check ring, and the other side of the fracture surface constitutes the tail end 2 end surface of the check ring, and the first end 1 end surface and the tail end 2 end surface mutually abut.

[0014] The utility model changes the traditional open check ring structure design, so that the check ring does not exist in the circumferential direction The notch makes the contact surface between the check ring and the groove opened on the part increase after the check ring is assembled on the corresponding part (such as bearing, shaft, etc.), improves the limit speed capacity; in addition, compared with the traditional open check ring structure, the check ring can allow a larger change amount of opening degree, thereby making the service life longer; and when processing, only single knife cutting is needed, compared with the traditional check ring structure design, the processing is simpler, and the processing efficiency is higher.

[0015] As can be seen from the above, the utility model sets the check ring into the closed ring structure that the first end 1 and the tail end 2 mutually abut in the natural state, and the structure design changes the traditional open check ring structure design, so that the check ring does not exist in the circumferential direction The notch makes the contact surface between the check ring and the groove opened on the part increase after the check ring is assembled on the corresponding part, improves the limit speed capacity; in addition, compared with the traditional open check ring structure, the check ring can allow a larger change amount of opening degree, which can effectively improve the service life of the check ring on the one hand and effectively improve the processing efficiency on the other hand.

[0016] In addition, in the embodiment, the width of the end where the first end 1 of the check ring is located and the end where the tail end 2 of the check ring is located is greater than the width of other parts of the check ring, to increase the closing strength of the cutting part, so that it is not easy to open to both sides, to protect the strength of the abutting surface, thereby protecting the stability after assembly.

[0017] Further, the first end 1 of the check ring and the tail end 2 thereof are provided with insertion holes 3 for inserting the jaws, during assembly, the two jaws are inserted into the insertion hole 3 of the first end 1 of the check ring and the insertion hole 3 of the tail end 2 of the check ring respectively, and the jaws are pulled to open the first end 1 and the tail end 2 to both sides, so as to assemble the check ring on the shaft, and then the jaws are pulled out of the insertion hole 3.

[0018] In further, the retaining ring comprises a left side ring body 5 from the first end 1 to the bisector 4 and a right side ring body 6 from the second end 2 to the bisector 4, and the width of the left side ring body 5 and the right side ring body 6 decreases gradually from the bisector 4 to the end, which makes the retaining ring increase the resistance to open to both sides with the increase of the opening degree, and the opening can be closed quickly after loosening.

[0019] The above merely describes the preferred embodiments of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent substitutions or changes according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
