Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency of the prior art, a kind of gear grinding machines straight-line transmitting moving axis transmission mechanism is provided, it is rational in infrastructure, manufacturing process is simple, eliminated leading screw expand with heat and contract with cold influence, positional precision height, production cost to power transmission shaft low, be convenient to promote the use of.
For achieving the above object, the technical solution used in the present invention is: a kind of gear grinding machines straight-line transmitting moving axis transmission mechanism, comprise left socle, right support and the motor that is used to drive ball-screw, it is characterized in that: described motor power output shaft passes the left socle left side wall and is connected with the ball-screw left end that passes the left socle right side wall, described ball-screw left end is fixed by the left socle right side wall and the ball-screw left end is connected by bearing one with described left socle right side wall, described ball-screw right-hand member is fixed by right support and the ball-screw right-hand member is connected by bearing two with described right support, and described ball-screw right-hand member is provided with locking nut.
Described bearing one both sides are respectively arranged with gland and adjust cover one.
Described bearing two both sides are respectively arranged with dish spring one and dish spring two, are provided with between described dish spring two and the locking nut to adjust cover two.
Described motor power output shaft is connected by shaft coupling with the ball-screw left end.
The present invention compared with prior art has the following advantages:
(1) rational in infrastructure, manufacturing process is simple.This gear grinding machines straight-line transmitting moving axis transmission mechanism is rational in infrastructure, and production technology is simple;
(2) having eliminated leading screw expands with heat and contract with cold to influence, the positional precision height of power transmission shaft.This gear grinding machines straight-line transmitting moving axis transmission mechanism inside is provided with a pair of jump ring, has eliminated leading screw and has expanded with heat and contract with cold to the influence of power transmission shaft, thereby improved the positional precision of this mechanism greatly;
(3) make simple, production cost is low, be convenient to promote the use of.The a lot of parts of this gear grinding machines straight-line transmitting moving axis transmission mechanism all are convenient to produce, buy very much, thereby its production cost is very low, is convenient to promote the use of.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
