Technical Field
The invention belongs to electromechanical devices, and particularly relates to an overrunning clutch widely applied to mechanical engineering and a manufacturing method capable of improving the performance of the overrunning clutch.
Background
The overrunning clutch is a clutch widely applied to mechanical engineering. The overrunning clutch has stable operation, can be automatically engaged as long as the driving part and the driven part have a rotation speed difference at any rotation speed, has sensitive reaction, and is a clutch with good performance.
The overrunning clutch transmits torque through the self-locking action between the balls and the inner ring and the outer ring. The bearing characteristic of the bearing is that the positive pressure between the ball and the inner ring and the positive pressure between the ball and the outer ring are very large, so that the force borne by the inner ring and the force borne by the outer ring and the contact stress between the ball and the inner ring and the contact stress between the ball and the outer ring are very large, and the inner ring and the outer ring are required to have very high strength and very high hardness. At present, the inner ring and the outer ring of the overrunning clutch are made of materials with the same property, and the two requirements can not be met at the same time.
Therefore, it is important to improve the performance of the overrunning clutch in mechanical engineering.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and examples.
The invention provides a manufacturing method for improving the performance of an overrunning clutch, wherein the overrunning clutch is provided with an inner ring and an outer ring, the inner ring and the outer ring are respectively made of two materials with different properties, the inner ring is provided with a bimetallic ring with an outer ring and an inner ring, and the outer ring is provided with a double ring with an outer ring and an inner ring.
The outer ring of the outer ring is made of a material with high strength and good plasticity, and the inner ring of the outer ring is made of a metal material with high hardness and high compressive strength. The outer ring of the inner ring is made of a metal material with high hardness, and the inner ring of the inner ring is made of a metal material with high strength and good plasticity. The outer ring can be made of chrome molybdenum steel, and can also be made of chrome steel or other materials.
The inner ring and the outer ring of the outer ring and the inner ring are in interference fit for transmitting torque. When the overrunning clutch is installed, the outer ring is sleeved on the periphery of the inner ring, and the balls are arranged between the inner ring and the outer ring and are in contact with the inner wall of the outer ring.
Referring to fig. 1, the outer ring structure of the overrunning clutch of the present invention is schematically illustrated. The outer ring of the overrunning clutch consists of two circular rings, wherein the
The invention takes the outer ring of the overrunning clutch shown in figure 1 as an example, and illustrates that the outer ring of the overrunning clutch is made of two materials with high hardness, high strength and good plasticity, so that the outer ring not only can meet the hardness requirement of the overrunning clutch but also can meet the strength requirement of the overrunning clutch, and compared with the existing overrunning clutch, the outer ring of the overrunning clutch can transmit larger torque under the condition of the same structure size, and the torque can reach more than two times; that is, the structural size of the overrunning clutch of the present invention can be reduced considerably with the same transmission torque.
When the overrunning clutch works, the balls are in contact with the inner wall of the outer ring, and the contact stress of the balls is large. Therefore, the inner ring needs to be made of a material having high hardness. Since the material with high hardness is a brittle material, such as the die steel Gr15, the hardness is high but the impact energy is low, and the material cannot withstand large impact and the tensile strength is not high enough. Therefore, it is not sufficient to use only a material having high hardness. In order to meet the requirements of large stress and impact resistance, the outer ring needs to be made of materials with high strength and good plasticity, such as chromium molybdenum steel CrMo42, chromium steel Cr40 and the like.
The outer ring of the overrunning clutch outer ring is made of steel with high tensile strength. The outer ring of the outer ring can also be replaced by carbon fiber, the carbon fiber is wound on the inner ring of the outer ring, and proper tension is applied to the carbon fiber during winding.
The above-described method for manufacturing the outer race of the overrunning clutch is also applicable to the manufacture of the inner race, except that the outer ring of the inner race is made of a metal material with high hardness, and the inner ring of the inner race is made of a metal material with high strength and good plasticity.
Of course, those skilled in the art will recognize that the above-described embodiments are illustrative only, and not limiting, and that changes and modifications may be made thereto without departing from the spirit and scope of the invention as defined in the appended claims.
