Abstract
The invention provides a spiral gear drive bicycle with a space alternating shaft, which comprises a middle shaft, a back shaft and a fly wheel, wherein a middle shaft gear housing is internally provided with a pair of driving spiral gear and driven spiral gear, which are meshed with each other, the driving spiral gear is sleeved on the middle shaft, the driven spiral gear is connected with a driving shaft, the other end of the driving shaft is arranged in a back shaft gear housing, the end part of the driving shaft is connected with a back driving spiral gear, a back driven spiral gear meshed with the back driving spiral gear in the back shaft gear housing is sleeved on the back shaft, the back shaft is connected with the back driven spiral gear by a rolling needle, the fly wheel arranged on the back shaft is meshed with a driving plate by the gear arranged on the fly wheel, and the driving plate is sleeved on the back driven spiral gear and is fixedly connected with the back driven spiral gear. According to the spiral gear drive bicycle with the space alternating shaft of the invention, the driving shaft and two pairs of spiral gears meshed with each other are adopted in the driving of power, the spiral gear drive bicycle is large in overlap coefficient, and stable to run, as a small number of parts such as the middle shaft gear housing, the back shaft gear housing and the like adopt non-standard parts, the spiral gear drive bicycle is applicable to the characteristic of the large-scale production of the bicycle; therefore, the production cost can be greatly reduced, and the spiral gear drive bicycle is very convenient to assemble and maintain.
Description
Technical field
The present invention relates to a kind of space alternating axis spiral gear bicycle.
Background technology
Bicycle is the main running vehicle in our daily life, and what existing bicycle major part adopted is chain-driving.The bicycle of Bevel Gear Drive once appearred adopting on the market, but its complex structure, adopt that non-standard component is many, also inconvenience of assembling, maintenance, withdrawed from market soon.
Summary of the invention
The object of the invention just provide a kind of simple in structure, can adapt to that bicycle Quantity production characteristics, productive costs are low, assembling, space alternating axis spiral gear bicycle easy to maintenance.
Space of the present invention alternating axis spiral gear bicycle comprises axis, rear axle, flywheel, is characterized in; The active helical wheel and the driven helical gear of pair of meshing are set in the axis gear casing; Initiatively helical wheel is nested with on axis, and driven helical gear links to each other with transmission shaft through flat key, and is fixed on the transmission shaft through antifriction-bearing box, one direction thrust bearing, spacer and nut; The other end of transmission shaft is placed in the rear axle gear shell; The end of transmission shaft links to each other with back active helical wheel through flat key, and back initiatively helical wheel is fixed on the transmission shaft through antifriction-bearing box, one direction thrust bearing, spacer and nut, and the back driven helical gear that is meshed with back active helical wheel in the rear axle gear shell is nested with on rear axle; Rear axle is connected with the back driven helical gear through needle roller; The flywheel that is installed on the rear axle meshes through gear on it and dial, and dial is enclosed within on the driven helical gear of back also affixed with it, and transmission shaft is provided with sleeve pipe outward; The two ends of sleeve pipe link to each other with axis gear casing, rear axle gear shell respectively, also are provided with reinforced pipe between axis gear casing and the rear axle gear shell.
Space of the present invention alternating axis spiral gear bicycle; Transmission shaft and two pairs of helical wheels that are meshed are adopted in the transmission of power, and overlap coefficient is big, operates steadily; Owing to have only few parts such as axis gear casing, rear axle gear shell to adopt non-standard component; Characteristics that can adapt to bicycle Quantity production, so productive costs reduces greatly, assembling, maintenance are also very convenient.
