Abstract

The utility model relates to a strengthen lubricated class dustpan tongue line roller envelope end face worm transmission pair, including the terminal surface worm, the worm axle, the parallel key, the worm wheel, the roll teeth of worm wheel circumference distribution, the roll teeth is by the rolling element that can wind its self axis gyration, and the roll axis, the screw constitutes, the generating line of rolling element is class dustpan tongue line, and there is the honing line on the surface of rolling element, multiplicable its lubricating property, has the lubrication oil duct in the worm axle, and lubrication oil can follow the lubrication oil duct and flow for this transmission pair lubrication, and when the worm wheel meshing, the worm wheel meshing drives the rolling element simultaneously and rotates. The utility model discloses compare with traditional worm gear transmission pair and have the friction reduction, improve transmission efficiency, improve bearing capacity and promote advantages such as lubricating ability, have the practicality.

Description

Reinforced lubrication skip-like line roller enveloping end face worm transmission pair

Technical Field

The utility model relates to a mechanical transmission technical field especially relates to an it is vice to strengthen lubricated class dustpan hyoplastron roller envelope end face worm transmission.

Background

The worm transmission is a traditional mechanical transmission mode, and the traditional worm transmission has many defects, such as large sliding friction, insufficient lubrication, serious friction and abrasion, low transmission efficiency, large heat productivity, easy gluing, seizure and the like. Therefore, the research on a novel worm transmission form capable of solving the problems existing in the traditional worm form has important engineering application significance.

Disclosure of Invention

The utility model aims at solving the problem mentioned in the above-mentioned background art, provide a kind of reinforced lubricated class dustpan tongue line roller envelope end face worm transmission is vice.

The utility model discloses a technical scheme be, including the terminal surface worm, the worm axle, the parallel key, the worm wheel, the roll teeth that worm wheel circumference distributes, the roll teeth is by the rolling element that can revolve around its self axis, the roll axis, and the screw constitutes, the generating line of rolling element is class tongue line, adopts the generating line advantage of class tongue line shape to be, and roll teeth top department radius is little, can prevent the card of meshing in-process when not repairing the shape with the tooth top from dying, and roll teeth root department radius can strengthen roll teeth intensity greatly, and there is the honing line on the surface of rolling element, multiplicable its lubricating property, has the lubricated oil duct in the worm axle, and lubricating oil can follow the lubricated oil duct and flow and give this transmission pair lubrication.

When the worm gear and the worm are meshed, the worm gear rotates and meshes and drives the rolling body to rotate. The relative sliding between the meshing tooth surfaces of the traditional worm gear is converted into rotation. The friction is reduced.

The utility model discloses compare with traditional worm gear transmission pair and have the friction reduction, improve transmission efficiency, improve bearing capacity and promote advantages such as lubricating ability, have the practicality.
