Title:
RUDDER-SHAPED ROLLER GEAR AND ARCHED-SURFACE-ENVELOPED GEAR ENGAGED DRIVE STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2012/010042
Kind Code:
A1
Abstract:
A rudder-shaped roller gear and arched-surface-enveloped gear engaged drive structure is disclosed. Rollers (3-1, 3-2) are equidistantly installed in the drive mating surface of the rudder-shaped roller gear (1), and the profile of the arched-surface-enveloped gear (2) is a surface of revolution formed by a concave arc revolving around the axis of the gear. On the surface of revolution there are helical rail grooves which can be engaged with rollers (3-1, 3-2). The rudder-shaped roller gear (1) and the arched-surface-enveloped gear (2) are simultaneously engaged by several rollers (3-1, 3-2), and the arched-surface-enveloped gear (2) forms an envelope to the rudder-shaped roller gear (1). Compared with a gear transmission, the structure has advantages of large transmission ratio, stable running, compact structure, small volume and no noise; and compared with a worm transmission, the structure changes the sliding friction between the gear teeth of the worm and the worm wheel into the rolling friction of the rollers, such that the structure has advantages of small abrasion, long service life, high efficiency, low energy consumption, large loading force and large designed transmission ratio range. The manufacturing of the rudder-shaped roller gear processes the gear teeth without using the way of rolling the teeth and inserting the teeth, but processes the assembled structure using the simple drilling, milling and twisting way, such that the manufacture cost is low.
