Abstract

This utility model comprises a gear 1, a spline wheel 2, a roller 5, a pad 3 and a garter spring 4. Inner spline holes are provided at axial center of the gear 1. Inside the inner spline holes of the gear 1 are provided with the roller 5 and spline wheel 2. The roller 5 is installed after arranging the spline wheel 2 in the inner spline holes. Thereafter, the pad 3 and garter spring 4 are arranged at two axial ends of the spline wheel 2. The spline wheel 2 and the roller 5 are positioned on the gear 1 by the pad 3 and garter spring 4. The utility model positions the spline wheel and roller on the gear by pad and garter spring to form an entirety. The combining manner of relative movement under micro friction between the spline wheel and the gear can be kept constant due to relative positions of the spline wheel, roller and gear. The external circumference of the spline wheel has a smooth surface. This utility model improves service life as well as torque force.

Description

The gear gasoline-saving device

Technical field

The utility model relates to gear, a kind of specifically gear gasoline-saving device.

Background technique

Its structure of gear gasoline-saving device of Shi Yonging is to be made of inside and outside gear basically in the market, and the joining place of inside and outside gear is roller fixedly, thereby keeps the relative movement under the slight Frotteurism of inside and outside gear.The internal surface of the external gear of common oil-saving gear is a smooth surface, and such structure, its shortcoming are that the diameter of internal gear is little, causes working life not long.

The model utility content

The purpose of this utility model is to solve problem that prior art exists a kind of gear gasoline-saving device that has improved is provided.

The technical solution of the utility model is: a kind of gear gasoline-saving device, it is characterized in that: the gear gasoline-saving device is made of gear, spline wheel, roller, pad and jump ring, axial centre at gear is provided with inner splined hole, in the inner splined hole of gear, be provided with roller, spline wheel, the spline wheel places arrangement roller in back in the inner splined hole, at the axial two ends assembling pad and the jump ring of spline wheel, spline wheel and roller are positioned on the gear then by pad and jump ring.

The axial two ends of described spline wheel are provided with convex shoulder, and convex shoulder is provided with annular groove, and annular groove cooperates with pad and jump ring, and the axial centre of taking turns at spline is provided with inner splined hole, and the excircle of spline wheel is a smooth surface.

The beneficial effects of the utility model are: by pad and jump ring the spline wheel is positioned at roller and becomes as a whole on the gear, because the relative position of spline wheel, roller and gear, thereby keep the compound mode of the relative movement under spline wheel, the slight friction of gear to remain unchanged, the excircle of spline wheel is a smooth surface, improved working life, torque also is improved.
