Abstract

The invention discloses an overload-preventing speed reducer for a tunnel type drying room. The speed reducer comprises a box, wherein a worm shaft is arranged on the box, one end of the worm shaft extends out of the box to be connected with a motor, an output shaft with two ends extending out of two sides of the box respectively is arranged in the box, a worm gear meshed with a worm on the worm shaft is arranged on the output shaft, the output shaft is a tube fitting, and inwards concave grooves which extend axially are formed in ends of the output shaft. The speed reducer can be installed in the transverse middle of the drying room to transmit power to two sides, so that a transmission shaft is shortened, and the stress uniformity of the transmission shaft is improved; when the speed reducer is connected with the transmission shaft of the drying room, shear keys can be inserted in the inwards concave grooves, long grooves are also formed in corresponding positions of the transmission shaft, and the output shaft and the transmission shaft are connected sequentially; when overload exists during usage, the shear keys can be cut off quickly, transmission connection of the transmission shaft and the speed reducer can be disconnected, and the motor is prevented from being damaged.

Description

A kind of tunnel type drying room antioverloading speed reducer
Technical field
The present invention relates to a kind of tunnel type drying room antioverloading speed reducer.
Background technique
The tunnel type drying room of producing for vermicelli relies on chain transmission to transmit, after motor slows down by speed reducer, power drives respectively through traversing the transmission shaft of drying room each sprocket rotation being arranged on transmission shaft, existing drying room transmission system, conventionally speed reducer is arranged on to drying room one side, between sprocket wheel and transmission shaft, by flat key, be connected, this structure, cause propeller shaft length long, bumpy motion, stressed transmission shaft is uneven, when main is transmission system generation overload, cannot cut off and speed reducer, motion between motor, directly to speed reducer, motor causes damage.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency of prior art, a kind of tunnel type drying room antioverloading speed reducer is provided, guarantee that stressed transmission shaft is even, improve transmission system antioverloading ability.
The technical solution adopted for the present invention to solve the technical problems is: a kind of tunnel type drying room antioverloading speed reducer, comprise casing, described casing is provided with worm shaft, worm shaft one end is stretched out outside casing and is connected with motor, in casing, be provided with two ends and stretch out respectively the output shaft of casing both sides, output shaft be provided with worm shaft on the worm gear of worm meshing, output shaft end has and extends axially inner groovy.
Furtherly, described output shaft is pipe fitting,
The invention has the beneficial effects as follows: the present invention adopts after said structure, when speed reducer is connected with drying room transmission shaft, shear key is inserted in inner groovy, elongated slot is also offered in transmission shaft relevant position, according to this output shaft is connected with transmission shaft, runs into when overload in use, shear key can fast shut-off, disconnect being in transmission connection of transmission shaft and speed reducer, prevent that motor from damaging; And speed reducer is owing to having the output shaft that minute is located at casing both sides, speed reducer can be arranged on the horizontal neutral position of drying room, to both sides transferring power, thereby has shortened propeller shaft length, has improved stressed transmission shaft uniformity.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
1. casing 2. worm shaft 3. output shaft 4. worm gear 5. inner groovies in figure.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention is only described in a schematic way, so it only show the formation relevant with the present invention.
A kind of tunnel type drying room antioverloading speed reducer as shown in Figure 1, comprise casing 1, described casing 1 is provided with worm shaft 2, worm shaft 2 one end are stretched out outside casing 1 and are connected with motor, in casing 1, be provided with two ends and stretch out respectively the output shaft 3 of casing 1 both sides, output shaft 3 be provided with worm shaft 2 on the worm gear 4 of worm meshing, described output shaft 3 is pipe fitting, output shaft 3 ends have axially extended inner groovy 5.
The present invention adopts after said structure, when speed reducer is connected with drying room transmission shaft, shear key is inserted in inner groovy 5, elongated slot is also offered in transmission shaft relevant position, according to this output shaft 3 is connected with transmission shaft, runs into when overload in use, shear key can fast shut-off, disconnect being in transmission connection of transmission shaft and speed reducer, prevent that motor from damaging; And speed reducer is owing to having the output shaft 3 that minute is located at casing 1 both sides, speed reducer can be arranged on the horizontal neutral position of drying room, to both sides transferring power, thereby has shortened propeller shaft length, has improved stressed transmission shaft uniformity.
The above-mentioned foundation desirable embodiment of the present invention of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this invention technological thought, carry out various change and modification completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to claim scope.
