Forward and backward motion type center shaft transmission mechanism

Abstract

The invention discloses a forward and backward motion type center shaft transmission mechanism. The forward and backward motion type center shaft transmission mechanism comprises a center shaft cylinder, a circular cross, occlusion small gears and fracture-surface gears, wherein the circular cross, the occlusion small gears and the fracture-surface gears are located in the center shaft cylinder. The occlusion small gears are installed on the periphery of the circular cross, a fracture-surface gear center shaft penetrates through the middle of the circular cross, and the fracture-surface gearsare installed at the two ends of the fracture-surface gear center shaft correspondingly in a sleeving mode; and the gear ends of the fracture-surface gears are installed at the two ends of the fracture-surface gear center shaft in a sleeving mode and engaged with the occlusion small gears, the rotary shaft ends of the fracture-surface gears extend out of the center shaft cylinder, the portions, inthe center shaft cylinder, of the rotary shaft ends are sequentially sleeved with bearings and center shaft locking covers, and the fracture-surface gears are fixed to the two ends of the center shaft cylinder through the center shaft locking covers. According to the forward and backward motion type center shaft transmission mechanism, the transmission efficiency is improved, the invalid processin the transmission process is reduced, the forward and backward motion type center shaft transmission mechanism can be applied to different fields, the cost of the transmission efficiency can be maximally reduced, and the number of complex mechanisms needing to achieve reciprocating motion in the transmission process is decreased.

Description

technical field [0001] The invention belongs to the field of mechanical transmission, and relates to a forward and reverse movement mode of a center shaft transmission mechanism, specifically a forward and reverse movement center shaft transmission mechanism; according to different fields of application, it can be driven by human power or can be It is driven by a motor or other transmission force. Background technique [0002] Traditional bicycle drive mode all is to do the drive of stepping on the circle mode. With the development of technology, there are also some technologies that continuously improve the driving method of bicycles. But according to known drive mode, also do not have a kind of drive mode that belongs to the present invention. [0003] The center shaft of the traditional riding driving method only serves as the fulcrum driving function for circular motion when riding. In the process of stepping on the maximum force angle on the force point, once the angl...

Problems solved by technology

[0003] The center shaft of the traditional riding driving method only acts as a fulcrum driving force for circular motion when riding. In the process of stepping on the maximum force angle on the force point, once the angle range exceeds the force point, Other angles are redundant movement process, just follow the transmission mechanism to do useless movement
