Abstract
A dual shaft positive and negative rotating output retarder comprises a gear retardment transmission mechanism, wherein a laid upper worm and a lower worm are arranged in the mechanism; the lower ends of the upper worm and the lower worm are connected to a final output transmission of the gear retardment transmission mechanism; but the upper worm and the lower worm transmit in a reversal direction; the mechanism is also rotatablely connected to a vertical output rotating shaft and a hollow output shaft cover which is coaxial with the a gap and covers the hollow output shaft cover; the output rotating shaft and the hollow output shaft cover are respectively connected to an upper worm wheel and a lower worm wheel; wherein the upper worm wheel and the lower worm wheel correspondingly joggles the upper worm and the lower worm. The utility model is simplistic in structure, few in special parts, convenient in processing, reliable in transmission and relatively large in retardment ratio; moreover, the mechanism is compact in structure, small in volume and reduces installing space.
Description
Technical field: the utility model relates to a kind of speed reducer, particularly with the supporting speed reducer of stirrer.
Background technique: the stirrer of using in food, medicine and other fields generally stirs liquid medium, and supporting speed reducer has only an output shaft usually, and stirrer paddle can only a direction rotate, and mixing effect is not enough.The speed reducer that double-shaft counter-rotating output has also been arranged now, but drive mechanism all is the cone gear gearing down, structure is complicated, volume is bigger, it is big to be contained in the installing space that needs on the stirrer, and the reduction speed ratio excursion of Bevel Gear Drive is too little, if require lower rotating speed output, must connect the first class reducer structure again at input end, make the entire machine structure more complicated.
Summary of the invention: at the deficiencies in the prior art, it is a kind of simple and compact for structure that the utility model provides, the double-shaft counter-rotating output speed reducer that the reduction speed ratio scope is bigger.
The gear reduction driving mechanism that the utility model comprises body and is placed in one, also be provided with horizontal last worm screw and following worm screw in the body, the end of last worm screw and following worm screw all is in transmission connection with the output final stage of gear reduction driving mechanism, and both transmission sense of rotation are opposite, also be rotatably connected to output revolving shaft and concentric gap cover hollow output shaft cover thereon longitudinally in the body, put in output revolving shaft and hollow output shaft and be fixedly connected with worm screw and following worm screw in worm gear and the corresponding engagement of following worm gear respectively.
Of the present utility model simple in structure, special-purpose member is few, and is easy to process, reliable transmission, the reduction speed ratio scope is bigger, can the slow-speed of revolution double-shaft counter-rotating output and stirrer two metaplasm leaf rotation directions can be installed when supporting and work on the contrary, improve mixing effect.And, adopting the compact structure that makes machine behind the worm and gear, volume is little, reduces installing space.
Further specify the utility model below in conjunction with drawings and Examples.
Description of drawings: Fig. 1 is embodiment's a main structure schematic representation;
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment: as shown in the figure, be equipped with gear reduction driving mechanism 2 in the body 1, also be provided with horizontal last worm screw 3 and following worm screw 4 in the body 1, the end of last worm screw 3 and following worm screw 4 all is in transmission connection with the output final stage of gear reduction driving mechanism 2, and both transmission sense of rotation are opposite.Also be rotatably connected to output revolving shaft 5 and concentric gap cover hollow output shaft cover 6 thereon longitudinally in the body 1, be fixedly connected with worm screw 3 and following worm screw 4 in worm gear 7 and the 8 corresponding engagements of following worm gear on output revolving shaft 5 and the hollow output shaft cover 6 respectively.
With the supporting use of stirrer the time, the output shaft of motor 9 is connected with gear reduction driving mechanism 2, go up worm screw 3 and following worm screw 4 mutual counterrotatings after the gearing down, going up worm gear 7 by the correspondence engagement like this makes the rotation direction of output revolving shaft 5 and hollow output shaft cover 6 opposite with following worm gear 8, the two metaplasm leaves that are installed in respectively on them promptly oppositely stir, and stirring efficiency is improved.
