Embodiment 1

[0021] Embodiment one: figure 1 , figure 2 with image 3 Among them, the transmission is mainly composed of the first shaft (4), the second shaft (8), a multi-turn bevel gear (5) on the first shaft, multiple bevel gears (10, 12, 13) on the second shaft , 14), gear shift fork (7) and transmission housing (15). The first shaft is the power input shaft, and the second shaft is the power output shaft. The first shaft (4) and the second shaft (8) intersect perpendicularly, and a multi-turn bevel gear (5) fixed to the shaft as a whole is sleeved on the first shaft. One of the multi-turn bevel gears (5) There are multiple rings of gear teeth distributed on the side, and each ring of teeth forms a ring gear. Each ring gear (1, 2, 3) takes the gear axis as the center and has different radii. The function of each ring gear is equivalent to a cone. gear. The second shaft can move in the axial direction, and there are multiple bevel gears (10, 12, 13, 14) on it, and each bevel gear ...

Abstract

The invention relates to a spline shaft gear selecting bevel gear transmission. A first shaft (4) is perpendicular to a second shaft (8). The first shaft is sleeved with a multi-turn gear tooth bevelgear (5), wherein the multi-turn gear tooth bevel gear (5) and the shaft are fixed into a whole. Multiple gear rings (1, 2 and 3) different in radius are arranged on one side of the multi-turn gear tooth bevel gear. The second shaft is sleeved with multiple bevel gears (10, 12, 13 and 14) capable of rotating on the shaft, and the bevel gears (10, 12, 13 and 14) are engaged with the gear rings (3,3, 2 and 1) correspondingly to form multiple transmission ratios and turning directions. A reverse shift fork (7) is shifted to enable the second shaft (8) to axially move by a distance, an external spline (11) of the second shaft penetrates into an internal spline (9) of a certain bevel gear, the second shaft is connected with the bevel gear, and the transmission selects the transmission ratio and turning direction which the bevel gear participates in. In a similar way, the transmission selects other transmission ratios and turning directions. The number of the gears of the transmission is low, the reverse shift fork is arranged, the structure is extremely simplified, the size is small, the weight is small, and the transmission is suitable for bicycles, motorcycles and the like.

Description

technical field [0001] The invention relates to a gear transmission, a spline shaft gear selection bevel gear transmission and a bicycle transmission. Background technique [0002] There are multiple sets of gears on each shaft in a two-shaft or three-shaft gearbox to form different transmission ratios and possible rotation directions. There are generally multiple coupling sleeves or sliding gears in the gearbox, and the shift fork shifts Move the combined sleeve or slide the gear to change the meshing position of the gears in the gearbox for speed change or direction change. Two-shaft or three-shaft gearboxes are complicated in structure, large in volume and heavy in weight, and can be applied to automobiles, but are difficult to be applied to bicycles. How to reduce the structure of a two-shaft or three-shaft gearbox, save the combination sleeve, reduce the number of gears by half, replace multiple shift forks with one shift structure, greatly reduce the volume and weight...
