Two planar enveloping worm gear pair is based on a plane as base surface through the relative circular motion,envelope hourglass worm tooth surface, and then to the tooth surface of the worm as base surface,through the relative motion of a worm gear tooth surface envelop processed by this method the worm rod pair,with the folowling characteristics:
Large bearing capacity
Two planar enveloping hourglass worm can multiple tooth meshing,increases the contact aera,reduces the tooth face pressure,bear the heavy shock load.
The contact line of the worm and the worm wheel is along the tooth height direction,and the tooth surface meshing in contact stressed is reduced .
A worm and a worm gear in mesh at the same time there are two contact lines into the aera.This increase in the number and the meshing teeth,can improve the bearing capacity.
The worm tooth surface precision grinding,surface roughness Ra0.8.Worm geometry size and higher quality and surface roughness,ensure that wear to prevent the destruction of the oil film and high load.
Worm wheel tooth surface is after nitriding heat treatment after refined,tooth surface hardness HRC is more than or equal to 50,the worm high hardness in the design to ensure that there is no effect of the meshing characteristics of rigid enough that the bending and other factors.
Large slip angle
Owing to the great sliding between the contact line and the relative sliding velocity direction angle and sliding along the direction of relative curvature radius,resulting in between teeth good lubrication condition is the main reason for high efficiency.
Meshing small friction coefficient.
Tooth surface lubrication angle is large,easy to form the meshing dynamic pressure oil film,reduce the abrasion of the tooth surface of worm precision grinding,after engaging the friction coefficient to the minimum.
Lower noisness and smoother function
For avoid worm shock load ,the entrance of worm has been special fabricated.
Large scope of transmission ratio
For large scope transmission ratio,we could add the numerable of gear teeth in the design.So a single reducer has a large scope of transmission ratio.
Material and heat treatment method of high quality
The plane enveloping toroidal worm reducer worm two in CrMo steel iron nitriding treatment is of high quality,the worm is centrifugal casting made of phosphor bronze,can obtain reliability load capacity.
Compact dimension
Two planar enveloping worm gear can transmit power is high ,and the power structure is compact and reasonable value.
Long service life
The use of two plane enveloping worm in your device not only reduce the speed reducer,reducer volume,but also can make use of the whole machine is improved,prolong the service life,reduce the time of maintenance and repair of equipment,enable you to obtain higher efficiency.
