Description

Technical Field

[0001] The present invention mainly discloses a ratchet ring, particularly a ratchet ring with chip breaking grooves. Prior Technology

[0002] A ratchet wrench includes a wrench body. Within the head of the wrench body, a pawl, a spring, and a ratchet ring are fitted together. The ratchet ring has ratchet teeth on its outside, and the spring drives the pawl to maintain engagement with the ratchet teeth, thereby forming a unidirectional mechanical mechanism. The pawl prevents the transmission mechanism from reversing, ensuring that the ratchet ring can only rotate in a specific direction. A ratchet wrench that operates using a ratchet mechanism can generate unidirectional torque simply by rotating it back and forth, without needing to re-engage it after each rotation.

[0003] However, the chips generated by the ratchet teeth on the outside of the aforementioned ratchet ring are not easily cut off and removed during the machining process.

[0004] In view of the shortcomings of the above-mentioned conventional structures, the inventors have designed a ratchet ring with chip breaking grooves, which can overcome all the disadvantages of the above-mentioned conventional structures. Summary of the Invention

[0005] The main objective of this invention, a ratchet ring with a chip-breaking groove, is to provide a ratchet ring comprising a body, wherein the outer periphery of the body is provided with a ring tooth portion and a chip-breaking groove centered on a virtual rotating axis, wherein each ratchet tooth of the ring tooth portion extends in a direction parallel to the rotating axis, and the chip-breaking groove surrounds the body and is connected to one end of the ring tooth portion along the axial direction of the rotating axis. The ratchet ring, through the above structure, facilitates the cutting and discharge of chips during machining.

[0006] The minimum distance from the inner periphery of the chip-breaking groove to the shaft forms a first radius, and the minimum distance from the outer periphery of the ring tooth to the shaft is greater than the first radius.

[0007] The outer periphery of the body is provided with a retaining ring groove centered on the pivot. The retaining ring groove surrounds the body and is located on the side opposite to the ring tooth portion of the chip breaking groove.

[0008] The chip breaking groove has a first width along the axial direction of the rotating shaft, and the retaining ring groove has a second width along the axial direction of the rotating shaft, wherein the first width is smaller than the second width.

[0009] The minimum distance from the inner periphery of the retaining ring groove to the pivot forms a second radius, which is smaller than the first radius.

[0010] Other objects, advantages, and novelty of the invention will become more apparent from the following detailed description and the accompanying drawings. Simple Explanation of the Diagram

[0011] Figure 1: A perspective view of the ratchet ring with chip breaking groove of the present invention. Figure 2: A plan view of the ratchet ring with chip breaking groove of the present invention. Implementation

[0012] The techniques, methods, and effects employed in this invention are described in detail below with reference to the accompanying drawings. This is for illustrative purposes only and is not limited to this structure in patent applications.

[0013] Referring to Figures 1 and 2, these are perspective and plan views of the ratchet ring with chip-breaking grooves of the present invention. The ratchet ring 10 of the present invention includes a body 20; wherein:

[0014] The outer periphery of the body 20 is provided with a ring tooth portion 21 and a chip breaking groove 22 centered on a virtual rotating shaft L. Each ratchet of the ring tooth portion 21 extends in a direction parallel to the rotating shaft L. The chip breaking groove 22 surrounds the body 20 and is connected to one end of the ring tooth portion 21 along the axial direction of the rotating shaft L.

[0015] The minimum distance from the inner periphery of the chip-breaking groove 22 to the rotating shaft L forms a first radius R1, and the minimum distance from the outer periphery of the ring tooth portion 21 to the rotating shaft L is greater than the first radius R1.

[0016] The outer periphery of the body 20 is provided with a retaining ring groove 23 centered on the rotating shaft L. The retaining ring groove 23 surrounds the body 20 and is located on the side of the chip breaking groove 22 opposite to the ring tooth portion 21.

[0017] The chip breaking groove 22 has a first width W1 along the axis of the rotating shaft L, and the retaining ring groove 23 has a second width W2 along the axis of the rotating shaft L. The first width W1 is smaller than the second width W2.

[0018] The minimum distance from the inner periphery of the retaining groove 23 to the rotating shaft L forms a second radius R2, which is smaller than the first radius R1.

[0019] The structure of the ratchet ring 10 through the chip-breaking groove 22 facilitates the cutting and removal of chips when machining the ring teeth 21.

[0020] Based on the above, the present invention has the following advantages:

[0021] 1. The present invention provides a ratchet ring with a chip-breaking groove, wherein the ratchet ring includes a body, the outer periphery of which is provided with a ring tooth portion and a chip-breaking groove centered on a virtual rotating axis, each ratchet tooth of the ring tooth portion extending in a direction parallel to the rotating axis, the chip-breaking groove surrounding the body and connecting to one end of the ring tooth portion along the axial direction of the rotating axis, the ratchet ring having the above structure facilitates the cutting and discharge of chips during processing.

[0022] However, the above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any changes in numerical values ​​or substitutions of equivalent elements, or equivalent changes and modifications made in accordance with the scope of the present invention's patent application, should still fall within the scope of the present invention's patent.
