Embodiment Construction

[0030] The specific embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0031] Such as figure 1 , 6 Shown is a single tension spring clutch relay device of the present invention, which includes a drive shaft 1 and a gear 2. The gear 2 has a hollow structure and is provided with internal teeth 4, the drive shaft 1 is provided with a shaft key 5, and the drive shaft 1 passes through the internal space of the gear 2. In the no-load state, the positions of the retaining shaft key 5 and the internal teeth 4 correspond, that is, the two overlap in the axial direction and are opposed to the two ends of the drive shaft 1 in the radial direction. A protrusion 9 is provided on one side of the gear 2, which is preferably cylindrical. The drive shaft 1 is provided with a through hole along the radial direction. A tension spring 3 passes through the through hole. The round shackles at both ends are fixed to the gear 2...

Abstract

The invention relates to a single extension spring type clutch relay device. The relay device comprises a gear and a driving shaft, wherein the gear is hollow and is provided with an inner tooth; the driving shaft penetrates through an inner space of the gear and is provided with a shaft key; the inner tooth and the shaft key are coaxial with each other in a shaft rotating space, and axial positions are overlapped; bulges are arranged on one side surface of the gear; a through hole is radially formed in the driving shaft; and one extension spring penetrates through the through hole in the driving shaft to be connected with the bulges on the gear. According to the relay device, the bidirectional clutch effect is realized through change of the relative angle of the driving shaft and the gear, problems of collision and interference caused by engagement and disengagement of the gear and a rack as well as non-synchronous dual-driving in the relay driving process are solved, and stable operation in the relay process in the dual-driving state is guaranteed.

Description

Technical field [0001] The invention relates to the field of transmission technology, in particular to a single tension spring type clutch relay device. Background technique [0002] During the operation of the PWR nuclear power plant, the reactor shutdown and refueling operation process requires the new / spent fuel assembly to be transported back and forth between the reactor building and the fuel building. The transportation path needs to carry the fuel assembly through the fuel transfer channel from a plant Transport to another plant. Due to the double-layer containment design of the third-generation nuclear power plant, the length of the fuel transfer channel has been greatly increased compared with the second-generation and second-generation improved nuclear power plants. The lengthening of the transportation path puts higher requirements on the drive system of the fuel transfer device . [0003] In the process of realizing the above-mentioned transportation of nuclear fuel a...
