Description
Technical field
The present invention relates to a kind of worm drive retarder, particularly relate to engagement cydariform worm drive retarder in a kind of heavy duty.
Background technique
Worm drive is mechanically operated a kind of principal mode, for transmitting motion and the power between two alternating axiss of space, there is gear range wide (a common stage gear ratio can reach 5～100), compact structure, volume is little, motion is steady, low noise advantages, is therefore widely used in the fields such as Aero-Space, boats and ships navigation, metallurgical mine, petrochemical industry, building light industry.Anything is the same with other, along with the development of productivity and industrial technology, has produced existing worm drive technology and can not meet the contradiction that reality is produced.Adopt the worm drive retarder of traditional outer gearing form to there is larger volume and heavier weight, thereby the growth requirement, particularly Aero-Space and guided-missile submarine etc. that can not meet all the more modern production technology take the growth requirement in heavily loaded field to the conditional spy of volume and weight.
At present, little, the lightweight interior engages worm gearing speed-reducer of volume both domestic and external has following two kinds:
Wang Limin proposes engagement retarder in a kind of hourglass worm, its worm screw is sphere in the axial direction, internal gear is roll sleeve tooth, worm and gear is that interior engagement, Surface of action are identical cambered surface, there is the advantages such as volume is little, lightweight, total number of teeth in engagement is many, noise is little, but the movable teeth that adopts axle center and roll sleeve to be combined to form because of internal gear, therefore its bearing capacity is not high.
The type of belt drive retarder that a kind of ellipsoid worm screw that the P.G á bor L á szl ó of Hungary Ni Laijihazuo institute proposes engages with interior worm gear, its ellipsoid worm screw is that turning is shaped, interior worm gear is processed by the hob cutting consistent with ellipsoid worm tooth shape, has the advantages such as compact structure, volume are little, lightweight, multiple tooth contact.But worm tooth-surface can not grinding, and therefore its tooth face hardness is not high, degree of finish is bad; Because interior worm gear utilizes hob cutting processing, therefore processing difficulties and interior worm gear can not be accomplished very little.There is the shortcoming that manufacturing difficulty, interior worm gear can not be too little and bearing capacity is not high in the type of belt drive retarder that therefore, this ellipsoid worm screw engages with interior worm gear.
Therefore, in order to meet Aero-Space and guided-missile submarine etc., the conditional spy of volume and weight is taken the growth requirement in heavily loaded field, need a kind of novel worm drive retarder, it is little, lightweight and be easy to the feature of processing that it had both had compact structure, volume, have again that multiple tooth contact, bearing capacity are high simultaneously, the advantage such as high lubricating effect and long service life, need little, the lightweight heavily loaded retarder of a kind of volume.
