Abstract
The utility model discloses a high-precision gear, comprising a gear column, a flange and a rolling column, wherein the flange is sheathed at two ends of the gear column, and the rolling column is disposed between the flange and the gear column; and the rolling column is cylindrical. By adopting the rolling column, the whole gear looks like a bearing, and the gear automatically adjusts a thrust surface of the gear column by the rolling column when the gear is meshed with a rack, so that the gear is preferably fit with the rack during running, and the running precision of the gear is improved.
Description
Technical field
The utility model relates to a kind of gear, is specially the gear that a kind of serviceability is good, precision is high.
Background technique
Gear is realized the mechanism of transmission by engagement.Along with the continuous development and the progress of science and technology, more and more higher to gear-driven required precision, traditional gear has not satisfied the requirement of high-accuracy mechanical, so need the high gear of a kind of transmission accuracy.
The model utility content
The model utility purpose: in order to solve the problems of the prior art, the utility model provides a kind of high class gear that adopts the bearing principle.
Technological scheme: to achieve these goals, a kind of high class gear described in the utility model comprises: Cylindrical Gear, flange and roller; Described flange is enclosed within the two ends of Cylindrical Gear, and roller is between flange and Cylindrical Gear; Described roller is cylindrical.Cylindrical Gear described in the utility model is preferably 8.
The utility model further improves the operation progress in order to improve the contact lifting surface area of wheel and rack, and described Cylindrical Gear integral body surrounds cylindrical.
Cylindrical Gear described in the utility model is cylindrical.
Beneficial effect: the utility model compared with prior art has following advantage:
1, adopted roller in the utility model, made whole gear as a bearing, in the engagement process of gear and tooth bar, gear is more fitted when making the wheel and rack operation by the stress surface of the automatic adjusting gear post of roller, has improved the running precision of gear;
2, adopt the bearing principle in the utility model, prolonged the working life of gear integral body, make gear more durable, need not often change, saved client's user cost;
3, roller described in the utility model is cylindrical, makes Cylindrical Gear more accurate when adjusting stress surface.
