Specific implementation mode
As shown in Figs 1-4, a kind of anti-deformation long-life worm gear reducer, including babinet 1, the babinet 1 is interior to be equipped with snail
Bar 2 and the worm gear 3 engaged with worm screw 2, the worm gear 3 are fixed on main shaft 4, and main shaft 4 and worm screw 2 connect with body pivot,
The both ends of the worm screw 2 pass through the first taper roll bearing component 5 and the second taper roll bearing component 6 and babinet 1 respectively
Rotation connection, the both ends of the main shaft 4 pass through third taper roll bearing component 7 and the 4th taper roll bearing component respectively
8 are rotatablely connected with babinet 1.It is fixed that first bearing positioning chamber 101, second bearing positioning chamber 102,3rd bearing are equipped on babinet 1
Position chamber 103 and fourth bearing positioning chamber 104, the first taper roll bearing component 5, the second taper roll bearing component 6, third circle
Taper roller bearing component 7 and the 4th taper roll bearing component 8 are respectively provided at first bearing positioning chamber 101, second bearing positioning
In chamber 102,3rd bearing positioning chamber 103 and fourth bearing positioning chamber 104.
The input terminal of worm screw, and the main shaft namely power output end that are connect with worm gear, are all rigid contacts, are located at worm screw
And the shaft strength on main shaft, therefore the service life of bearing, it is directly related to the service life of entire worm wheel gearbox.
The prior art realizes the rotation connection between worm screw 2, main shaft 4 and babinet 1 using deep groove ball bearing component.By
The tolerance for having several (being typically 2) between the ball and bearing outer ring and inner ring of deep groove ball bearing, when worm screw 2 and main shaft 4
When high-speed rotation, deep groove ball bearing will produce the bounce of distance corresponding with tolerance radially, prolonged to beat, and can cause
