Rotary worm 2.Bearing block bottom is provided with screwed hole, by nut 10 and the detachable connection of pedestal 1, replaceable single-thread worm or double
Line worm screw.
Pillar 3 is " L " type, and its lower end is bolted on pedestal 1, and upper end is provided with snail with the vertical direction of worm screw 2
Axle hole, and axis parallel is in pedestal 1, after the one end of worm-wheel shaft 5 passes through worm gear axis hole, by 4 sets of systems of worm gear above, and worm gear
4 are engaged with worm screw 2, and good position is fixed afterwards.The other end of worm-wheel shaft 5 is equipped with screw 6, can be seen by the rotation of screw 6
Examine the rotation direction of worm and gear, it is also possible to the latching characteristics of worm and gear is observed by rotary screw 6.
The inside of the pillar 3 is designed for hollow out, can so realize light-weight technologg, and the mechanism can be allowed more preferable in teaching
Practicality.
In order to mitigate weight, the worm gear 4 is provided with counterbore.
Bearing is provided with the worm-wheel shaft 5, worm gear can be made more laborsaving in transmission.
Beneficial effect:1. the characteristics of the utility model includes various different tooth forms, line number in Worm and worm-wheel gearing;
The transmission principle and meshing characteristic of worm and gear, have loaded onto bearing between worm-wheel shaft 5 and worm gear axis hole, and also bearing can be carried out
It is simple to introduce.
2. the bearing block of the utility model teaching aid is using being detachably connected, can by changing single-thread worm and multiple threaded worm,
The characteristics of making the clearer understanding multiple threaded worm transmission efficiency of student higher.
3. the other end in worm-wheel shaft 5 is equipped with screw 6, can observe the situation awareness worm-drive by rotating screw
It is capable of achieving the situation of auto-lock function.
4. the utility model has also done light-weight technologg in mechanism, employs many hollow out designs and has used a large amount of aluminium to close
Golden material, greatly reduces Faculty and Students in demonstration and the operation difficulty of experimentation.
