Abstract
The invention discloses a novel straight-tooth cylindrical transmission gear which comprises a wheel disc. A shaft hole is formed in the middle of the wheel disc, a first outer gear ring and a second outer gear ring are arranged at the two ends of the gear disc, the radius of the first outer gear ring is larger than that of the second outer gear ring, and the height of the first outer gear ring is two times that of the second outer gear ring. The first outer gear ring and the second outer gear ring are different and are reasonably designed, the service life of the gear is prolonged, the precision of the gear is increased, materials are reduced, the cost is lowered, strength is increased, breakage is avoided, transmission stability is improved through the design of the shaft hole structure, and mounting and dismounting are facilitated.
Description
Technical field
The present invention relates to a kind of mechanical drive part, particularly relate to a kind of Novel straight tooth cylinder driving gear.
Background technique
Gear transmission is the mechanical transmission utilizing the gear teeth of two gears to engage each other transferring power and motion.In all mechanical transmission, gear transmission is most widely used, can be used to transmit the motion between the not far diaxon of relative position and power.Powder metallurgical gear is difficult to independent statistics in whole powdered metal parts, but is no matter by weight or by number of spare parts, and the ratio shared in automobile, motorcycle of powder metallurgical gear is all far longer than the powdered metal parts in other field.Therefore, as can be seen from the rising of automobile, motorcycle proportion in whole powdered metal parts, powder metallurgical gear is in the status of develop rapidly in whole powdered metal parts.If divided by parts character, gear belongs to Structure type part, and the absolute weight of Structure type part shared by whole iron-base part is also far longer than other a few class powdered metal parts.But the deficiencies such as in currently available technology, research and development ability falls behind, and product specification is low, there is precision low, easy to wear, easy fracture.
Summary of the invention
The object of the invention is to overcome the defect existed in prior art, provide a kind of rational in infrastructure, precision is high, not the Novel straight tooth cylinder driving gear of easy-rupturing.
For achieving the above object, technological scheme of the present invention there is provided a kind of Novel straight tooth cylinder driving gear, include wheel disc, the middle part of described wheel disc is provided with axis hole, described wheel disc two ends are respectively equipped with the first external toothing and the second external toothing, described first external toothing radius is greater than the radius of described second external toothing, and the height of described first external toothing is 2 times of the second external toothing height.
In order to improve the accuracy of gear, preferred technological scheme is, the velocity ratio of described first gear ring and the second gear ring is 2: 3.
In order to stable transmission, described axis hole is stepped cylindrical body.
Produce in transmission to prevent gear and axle further and slide, preferred technological scheme is, described cylinder axis hole surface is provided with reticulate pattern.
In order to increase fastness, prevent fracture, preferred technological scheme is, described first external toothing and the second external toothing abutting end are provided with back-up ring.
In order to install, convenient disassembly, preferred technological scheme is, the axis hole of described first external toothing end is provided with annular groove.
Advantage of the present invention and beneficial effect are: the present invention is by the appropriate design to first, second different gear ring, increase the working life of gear, precision, reduce material, reduce costs, gain in strength, prevent fracture, by the design to axial aperture structure, improve the stability of transmission, convenient installation, dismounting.
Accompanying drawing explanation
Fig. 1 is plan view of the present invention;
Fig. 2 is worm's eye view of the present invention.
