Description

A worm gear reducer for filter tank

technical field

The utility model relates to the field of reducers, in particular to a worm gear reducer for stirring a filter tank.

Background technique

In the filter tank, it is generally necessary to use stirring equipment to stir to improve the filtration efficiency. Stirring in the prior art usually uses a stirring shaft to stir, because the position of the stirring shaft is fixed, it can only stay at the top or bottom for stirring, and the stirring effect is not good.

Contents of the invention

The purpose of the utility model is to provide a worm gear reducer for a filter tank that can be fully stirred.

The technical scheme that the utility model takes is:

A worm gear reducer for a filter tank, comprising a bracket, a lifting deceleration device and a rotation decelerating device are installed in the bracket, the lifting deceleration device includes a worm gear reducer, a first motor and a vertical lead screw, and the worm gear is coaxial Screwed to the lead screw, the worm is connected to the first motor; the rotation reduction device includes a reducer, a second motor and an output shaft, the second motor drives the output shaft through the reducer, and the lifting reduction device is installed on the bracket The top, the screw and the output shaft are coaxially connected through the guide mechanism, the top of the screw is fixedly connected to the bottom surface of the guide mechanism, the bottom end of the output shaft is supported on the top of the guide mechanism through bearings, the guide mechanism Both sides are respectively provided with horizontal guide rods, and the two sides of the bracket are respectively provided with guide grooves matched with the guide rods, and each guide rod passes through the corresponding guide grooves.

Further, the final gear of the reducer is fixedly sleeved on the shaft sleeve, and the shaft sleeve is supported in the box through bearings. The output shaft passes through the shaft sleeve, and the output shaft is connected with the keyway on the inner wall of the shaft sleeve by a flat key.

After adopting the above technical scheme, the beneficial effect of the utility model is: the rotation of the screw is realized by using the worm gear of the screw lifting device, the screw converts the rotation into linear lifting through the guide device, and promotes the lifting of the output shaft, and the rotation reduction device passes through The shaft sleeve drives the rotation output of the output shaft, and at the same time the keyway of the shaft sleeve cooperates with the key on the output shaft to realize the up and down movement of the output shaft; the output shaft moves up and down while rotating and stirring in the filter tank to make the stirring more uniform.

detailed description

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail:

As shown in the figure, a worm gear reducer for a filter tank includes a bracket 1, and a lifting deceleration device and a rotation decelerating device are installed in the bracket 1. The lifting deceleration device includes a worm gear reducer, a first motor 2 and a vertical Lead screw 3, the worm wheel 4 is coaxially connected to the lead screw 3, and the worm 5 is connected to the first motor 2; the rotation decelerating device includes a reducer, a second motor 6 and an output shaft 7, and the second motor 6 passes through The reducer drives the output shaft 7 to output. The final gear 8 of the reducer is fixedly sleeved on the outer wall of the hollow shaft sleeve 9. The shaft sleeve 9 is supported in the reducer box through bearings. The output shaft 7 passes through the shaft sleeve, and the output shaft 7 The flat key 10 is connected with the keyway on the inner wall of the shaft sleeve 9, the length of the keyway is longer than the length of the flat key 10, or the keyway is a keyway with openings at both ends; It is coaxially connected with the output shaft 7 via a guide mechanism 11, the top of the lead screw 3 is fixedly connected to the bottom surface of the guide mechanism 11, and the bottom end of the output shaft 7 is supported on the top of the guide mechanism 11 through bearings, and the guide mechanism 11 Horizontal guide rods 12 are respectively provided on both sides of the bracket 1, and guide grooves 13 that cooperate with the guide rods 12 are respectively provided on both sides of the bracket 1, and each guide rod 12 passes through the corresponding guide grooves 13.

During the working process, the lifting deceleration device drives the lead screw 3 to lift upwards, and the guide mechanism 11 limits the rotation of the lead screw 3 and at the same time drives the output shaft 7 to rise. The motor drives the shaft sleeve to rotate, and the shaft sleeve drives the output shaft 7 to rotate simultaneously by the flat key, so as to realize the simultaneous lifting and rotation of the output shaft.
