Embodiment Construction

[0031] See figure 1 , figure 2 with image 3 , The composite spring 5 is composed of an inner layer of spiral spring 3, a middle layer of spiral spring 2 and an outer layer of spiral spring 1. Each layer of spiral spring is composed of three rectangular spiral springs with a rectangular cross section, and the ends of the three spiral springs are evenly divided; The direction of rotation of the spiral spring is right-handed, and the direction of rotation of the middle-layer spiral spring is left-handed; the two ends of the composite spring 5 are respectively provided with a hexagonal through hole in the center of the first half coupling 4 and the second half coupling The step 6 provided at one end of 7 can be welded.

[0032] See Figure 4 with Figure 5 , The welding method of the composite spring type flexible coupling according to the present invention has the following steps:

[0033] The first step is the preparation of the solder: a sheet of silver solder with a thickness of...

Abstract

The invention relates to a compound spring type flexible shaft joint which comprises a first semi-shaft joint, a second semi-shaft joint and a compression spring connected between the first semi-shaft joint and the second semi-shaft joint; the invention is characterized in that: the compression spring is a compound spring which at least consists of one layer of more than two levo / dextral coil springs; two ends of the compound spring are fixed with one end of the first semi-shaft joint and one end of the second semi-shaft joint respectively. The invention also relates to a welding method of the compound spring type flexible shaft joint, which adopts the induction soldering technology and comprises the following steps that: flaky silver solders are punched and machined to two sheets of annular solders; firstly, one end of the compound spring is welded with the first semi-shaft joint, then the other end of the compound spring is welded with the second semi-shaft joint. The qualification rate of parts produced by the invention reaches 95 percent above; compared with the prior technology, the welding method of the compound spring type flexible shaft joint solidifies technological parameters, exists no problem of nonmetallic aging of the produced parts in the storage process, does not need to increase a mass of spare parts and reduces the cost.

Description

Technical field [0001] The invention relates to a coupling and a manufacturing method thereof, in particular to a composite spring type flexible coupling and a welding method thereof. Background technique [0002] The name of CN2462142Y announcement is "elastic coupling", which is composed of two spring seats hooked by the hooks at both ends of a compression spring, which acts as a flexible buffer when transmitting torque. The flexible coupling of a single spring is connected by a hook connection. This connection method makes the function of the elastic coupling not guaranteed. If the spring breaks, the entire coupling is scrapped. The composite spring-type flexible coupling can avoid such accidents, that is, the normal operation of the component can still be guaranteed when a spring breaks. The composite spring of the composite spring type flexible coupling is composed of at least two layers of spiral springs. Due to the small contact surface between the end surface of the coil ...
