Wherein, first stage decelerator 101 and two stage reduction gear are all arranged in housing 100, the worm screw 103 that two stage reduction gear comprises worm gear 102 and engages with worm gear 102, and first stage decelerator 101 is connected with worm screw 103 key.As shown in Figure 1 C, be the cross-sectional view of the worm gear 102 according to the present embodiment.
The housing 100 of the present embodiment can be provided with base (not shown), base is used for fixing first stage decelerator 101 and two stage reduction gear, first stage decelerator 101 and two stage reduction gear can not be subjected to displacement in the course of the work, and impact normally works.
Alternatively, the two stage reduction gear of the present embodiment also comprises worm-wheel shaft 104, and this worm-wheel shaft 104 is connected with worm gear 102 key.
Particularly, first stage decelerator 101 comprises input gear axle 1011 and gear 1012, this gear 1012 engages with input gear axle 1011, namely when input gear axle 1011 rotates, can rotate by driven gear 1012, and this gear 1012 engages with worm screw 103, namely gear 1012 rotates, and worm screw 103 can be driven to rotate.This gear 1012 is larger gear, and general diameter is 148.5mm-150mm, and accordingly, the tip diameter of the input gear axle 1011 engaged with this gear 1012 is 37.5mm-39mm.Input gear axle 1011 rotates main dependence pneumatic motor (not shown).
Alternatively, the worm screw 103 of the present embodiment is specially planar double-enveloping worm retarder (Planar Double-Enveloping Worm Gearing Reducer), i.e. TOP type worm screw.As shown in Figure 2, be the front view of this planar double-enveloping worm retarder.The precision of this planar double-enveloping worm retarder is high, face face is large, and have instantaneous doublet contact, Line of contact total length is long, composite curve radius reaches, contact stress is little, engagement profit Lubrication Angle is large, easily form dynamic pressure oil film in engagement, reduce temperature rise, reduce odontotripsis, and bearing capacity is large, efficiency is high, long service life.
In addition, planar double-enveloping worm retarder can possess auto-lock function, improves transmission efficiency, extends the working life of running gear.This possesses auto-lock function and refers to planar double-enveloping worm retarder worm gear 102 can be driven to rotate, but worm gear 102 can not drive planar double-enveloping worm retarder to rotate.
Specifically how making planar double-enveloping worm retarder belongs to prior art, does not repeat them here.
