Embodiment Construction
[0011] The present invention is described further according to accompanying drawing:
[0012] A three-speed bevel gear transmission box, mainly composed of an input shaft 1, an input forward bevel gear 2, an inner and outer spline sliding sleeve 3, an input reverse bevel gear 4, a ball bearing I5, an output bevel gear 6, an output shaft 7, and a box Body 8, ball bearing II9, handle 10, driving lever 11 etc. are formed. According to attached figure 1 , input shaft 1, input forward bevel gear 2, inner and outer spline sleeves 3, input reverse bevel gear 4, ball bearing I5, output bevel gear 6, output shaft 7, ball bearing II9, lever 11 etc. One side of the inner hole of the input forward bevel gear 2 and the input reverse bevel gear 4 is a light hole, respectively connected to the input shaft 1 through the ball bearing II9 and the ball bearing I5, and the other side is an inner spline. The inner spline teeth can be engaged with the outer spline teeth on the inner and outer sp...

The invention belongs to the mechanical field, particularly relating to a gear transmission device, in particular to a revering three-gear primary conical gear transmission box. The invention mainly consists of an input shaft 1, an input positive conical gear 2, an internal spline sliding sleeve and an external spline sliding sleeve 3, an input inversing conical gear 4, a ball bearing 5, an output conical gear 6, an output shaft 7, a box body 8, a ball bearing 9, a handle 10, a pulling rod 11, etc. The internal spline sliding sleeve and the external spline sliding sleeve 3 are connected with the spline of the input shaft 1 and can slide forwards and backwards on the input shaft 1 under the action of the handle 10 and the pulling rod 11. By changing the position of the internal spline sliding sleeve and the external spline sliding sleeve 3 on the input shaft 1, the switch of three gears of the gearbox can implemented. In the position I, the gearbox is arranged in the positive gear, and the output shaft 7 rotates positively; in the position II, the gearbox is in the neutral gear, and the output shaft 7 is not rotated; in the position III, the gearbox is in the negative gear, and the output shaft 7 rotated reversely. The invention has the advantages of simple and compact structure, high reliability, richening the power output modes of the gearbox and widening corresponding equipment function and applicable range by taking the main working part as the conical gear.
Description
technical field [0001] The invention belongs to the field of machinery, and in particular relates to a gear transmission device, in particular to a reversible three-gear one-stage bevel gear transmission box. Background technique [0002] In the existing technology, there are various forms of traditional gear transmission boxes or gearboxes, but most of them are single-input and single-output. However, the existing reversible three-gear one-stage bevel gear transmission boxes often have larger dimensions, more complex structures, greater difficulty in production, and many factors affecting service life and reliability, which to a certain extent limit the relevant Application of mechanical equipment. Contents of the invention [0003] The purpose of the present invention is to provide a new type of reversible three-speed one-stage bevel gear transmission box with relatively simple structure, so as to enrich the power output mode of the gearbox and broaden the functions and...
