Transmission shaft connecting structure and application thereof

Abstract

The invention discloses a transmission shaft connecting structure. The transmission shaft connecting structure comprises a transmission shaft, and a mounting hole is formed in one end of the transmission shaft; a screw rod is inserted in the mounting hole, a coupling is arranged at the end, away from the transmission shaft, of the screw rod, and an extrusion head is arranged at the end, inserted into the mounting hole, of the screw rod; a conical part is arranged at one end, away from the screw rod, of the extrusion head; the periphery of the extrusion head is sequentially sleeved with an expansion sleeve and an elastic sleeve; the side peripheral wall of the conical part props up the expansion sleeve, and presses the expansion sleeve and the elastic sleeve on the inner peripheral wall ofthe mounting hole; and the screw rod is sleeved with a limiting gasket, the screw rod is further provided with a nut, and the nut locks the limiting gasket to the transmission shaft. The connecting structure has large elasticity and an adjustable range, and can adapt to sizes within a certain range. The connecting structure is provided with the elastic sleeve, so that buffering is achieved to a certain extent, stress is dispersed on the inner circumferential face of the mounting hole of the transmission shaft, the stress peak value is reduced, and the situation that the transmission shaft is broken and damaged due to stress concentration is avoided.

Description

technical field [0001] The invention relates to a mechanical transmission structure, in particular to a transmission shaft connection structure and a chain furnace using the transmission shaft connection structure. Background technique [0002] In the mechanical transmission structure, it is rarely done, and it is difficult to achieve a power transmission system with a single transmission shaft and no connection structure. The above-mentioned power transmission system is difficult to design, difficult to process, and high in cost, so it is not suitable for application in general industrial fields. However, in the conventional transmission structure, certain technical means must be used to connect the transmission shafts for power transmission. [0003] As for the connection, in order to ensure stable transmission and reliable connection, finishing is generally required. But for some special materials, such as ceramics, quartz glass, etc., there are problems such as difficu...

Problems solved by technology

[0005] The present invention mainly relates to the transmission shaft of the aforementioned special material and the connection type described in the aforementioned classification ①, but the traditional solutions commonly used at present cannot cope with this situation

[0006] The traditional solutions commonly used at present all require a tight rigid connection between the connection structure and the transmission shaft, and this connection method cannot be applied to the aforementioned special materials because: ① Its processing accuracy is low and it cannot be perfectly matched with the traditional connection structure; ② It is fragile and fragile, and various fastening measures cannot be applied to it, such as set screws, etc.

[0007] In addition, chain-type annealing furnaces for silicon wafer production often use transmission shafts made of special materials. However, due to the imperfect connection structure of the existing transmission shafts, it will affect the stability of silicon wafers in the chain-type furnace during transmission, and even Increased offset during wafer tape-out
