Torque transmission flange structure and components and parts with flange structure

Abstract

The invention provides a torque transmission flange structure. According to the torque transmission flange structure, a flange is provided with threaded holes or through holes for penetrating bolts, and the connection end of the flange is provided with half-cylinder-shaped grooves perpendicular to the flange axis; perpendicular refers to the perpendicular of the axis line of the cylindrical surface which the half-cylinder surface is in to the flange axis line, two vertical lines in space may or may not intersect, for example, the axis lines of the half-cylinder-shaped grooves are machined on flange end face radius lines, namely the intersection vertical relation between the axis lines of the half-cylinder-shaped grooves and the flange axis line; and when the flange structure is connected with another flange equally provided with the torque transmission flange structure, cylindrical pins with the diameters being slightly larger than or equal to the diameters of the half-cylinder-shapedgrooves are put into the half-cylinder-shaped grooves corresponding to the two flanges, and the two flanges are locked by utilizing the bolts to make the two flanges clamp the cylindrical pins betweenthe two flanges tightly, and the larger load bearing and more accurate torque transfer effect is realized.

[0002] The flange structure is usually used for torque transmission in mechanical transmission, especially when the synchronization accuracy of the transmission is required to be high, the form of flange connection is often used. The traditional flange structure is to use bolts to connect the flanges of the two parts to each other. Locking, so that the two flange end faces are in contact, and the torque transmission is realized through the friction of the contact surface. Due to the limitation of the structure and appearance of the parts with the flange, the diameter of the flange is usually not easy to increase at will. In order to increase the flange transmission The torque and synchronous precision can be optionally penetrated by a pin or a key between the two flanges. The pin needs to be tightly matched with the holes on the two flanges to achieve better torque transmission effect. At this time, the requirements for tight pair processing are relatively high. At the same time, the tight fit also brings some troubles to assembly and disassembly, and the pressure of bolt locking between the two flanges does not increase the torque bearing capacity provided by the pins to the flange connection, and the use of keys increases the torque bearing capacity The method also has the above-mentioned problems and compared with precision pins and pin holes, the processing difficulty of precision keys and keyways is greater, and the precision machining of cylindrical pins is less costly than the precision machining of parts of the same precision grade in other shapes; in specific industries In the application, the performance requirements of the torque transmission flange are getting higher and higher, especially in precision machinery industries such as robots, which require high transmission accuracy, the size of the flange is limited, and at the same time, a large torque needs to be transmitted. It is particularly important to improve the torque bearing capacity and transmission accuracy of the flange
