Abstract

The utility model belongs to the field of mechanical transmission application and relates to a transmission worm gear pair with an end face enveloped by pin rollers. The worm gear pair is a special offset worm transmission pair and a worm gear and a worm can be used for transmitting motion and power between two alternating axes in space. According to the transmission worm gear pair with the end face enveloped by the pin rollers, a traditional end face gear is replaced by a rolling bearing, traditional sliding friction is changed to rolling friction, and the defects that a traditional end face worm gear pair is high in friction, low in transmission efficiency and high in manufacturing cost are overcome; meanwhile, the contact property and lubricating property are improved, and the worm gear pair has broad application prospects and promotional value.

Description

A kind of roller enveloping end face transmission worm gear pair

Technical field

The utility model belongs to mechanically operated application, relates to a kind of roller enveloping end face transmission worm gear pair, and this worm gear pair is a kind of special biasing worm transmission pair, and its worm gear and worm screw can be used to transmit motion and the power between two alternating axiss of space.Because it has, stable drive, physical dimension compactness, contact ratio are large, little, the advantage such as efficiency is high, cost is lower that rubs, so can use automobile, metallurgical machinery and other machinery equipments, have very wide application prospect and promotional value.

Background technique

Traditional end face Worm Wheel System, in the situation that accuracy of manufacturing is identical with velocity ratio and other conditions, its efficiency is relatively low; Simultaneously heating value greatly, easy gummed, the gear teeth generally need expensive antifriction material manufacture, cause cost high.Therefore, can produce that a kind of friction is little, efficiency is high, the secondary tool of lower-cost new type worm wheel is of great significance again.

Summary of the invention

In order to solve, the friction of traditional end face transmission worm gear pair is large, transmission efficiency and the high shortcoming of manufacture cost, the actual demand that the utility model produces according to above-mentioned situation, and a kind of roller enveloping end face transmission worm gear pair of proposition can meet these requirements just.

The utility model solves the technological scheme that its technical problem adopts: a kind of roller enveloping end face transmission worm gear pair, comprise: on worm gear (2), be uniformly distributed roller (3) and traditional rolling bearing for the gear teeth (5) is replaced, thereby the sliding friction during by traditional worm gear and worm drive becomes rolling friction.Solve the problem of traditional end face transmission worm gear pair with this.

Remarkable result of the present utility model is: after the gear teeth adopt rolling bearing (5) to replace, traditional sliding friction is become to rolling friction, not only make less traction, heating value reduction, efficiency improve, and manufacture cost reduction, easy for installation, contact performance and greasy property also improve simultaneously.
