Abstract
The utility model provides a decelerator for concrete agitator, comprising a housing, a plurality of pairs of spiral cone gears connected with the input shaft of the decelerator, and a plurality of cylinder helical gears whose input ends are connected with the spiral cone gears and output ends are connected with the output shaft of the decelerator. Because of adopting the spiral cone gear and the cylinder helical gear structure, the decelerator for concrete agitator provided by the utility model has improved transmission efficiency and convenient installation and disassembly.
Description
Technical field
The utility model relates to a kind of speed reducer, designs a kind of concrete mixer speed reducer especially.
Background technique
Speed reducer is the vitals in the concrete mixer power transmission.A kind of positive drive type that adopts has epicyclic transmission mechanism with the special retarding machine mechanism at present, though this compact structure is made and assembly technology requirement height, transmission efficiency is low, is about 70-75%; Worm and worm-wheel gearing, though more compact structure, transmission efficiency is lower, be about 60%, and heating value is big; Also having a kind of is that general speed reducer adds the open type gear transmission, and its structural adjustment size is big, and transmission efficiency is lower, and noise is big.The main deficiency of above-mentioned several reducing gear is that transmission efficiency is low, and energy consumption is big, not too is fit to the use of concrete mixer.
The model utility content
Technical problem to be solved in the utility model provide a kind of efficient higher, easy for installation coagulate native stirrer speed reducer.
In order to realize the foregoing invention purpose, the concrete mixer that the utility model provides includes housing with speed reducer, with the speed reducer input shaft link several to helical bevel gear, and that input end and described spiral awl tooth links, output terminal and speed reducer output shaft link is several to cylindric spiral gear.
The concrete that the utility model provides stirs special reduction gear owing to adopt helical bevel gear and cylindric spiral gear structure, and transmission efficiency improves greatly, simultaneously, and installation, convenient disassembly.
Description of drawings
Fig. 1 is a concrete mixer of the present utility model speed reducer outline drawing.
Fig. 2 is a concrete mixer of the present utility model speed reducer structural representation.
Embodiment
Referring to Fig. 1, concrete mixer of the present utility model is made up of two-part up and down with the housing 3 of speed reducer, and they are fixed by bolt 14, and input shaft 5 links to each other with the power source such as the motor of concrete mixer.Screw 11 links to each other with the housing 3 of concrete mixer.Be provided with a breather 12 in the screw 11, be used for enclosure interior is taken a breath.
Referring to Fig. 2, in housing 13, be provided with three pairs of gears, a pair of helical bevel gear 6, it is made up of king bolt bevel gear 61 and minor spiral bevel gear 62.Minor spiral bevel gear 62 links to each other with input shaft 5.King bolt bevel gear 61 links to each other with transmission shaft 21.In addition, a pair of cylindric spiral gear 7 is made up of cylindric spiral gear 71 and cylindric spiral gear 72, and cylindric spiral gear 71 links to each other with transmission shaft 21, and cylindric spiral gear 72 links to each other with transmission shaft 22; Another is made up of cylindric spiral gear 81 and cylindric spiral gear 82 cylindric spiral gear 8, and cylindric spiral gear 81 links to each other with transmission shaft 22, and cylindric spiral gear 82 links to each other with output shaft 23.This output shaft 23 adopts hollow shaft, can directly be enclosed within on the main shaft of stirrer, makes transmission more compact, and mounting or dismounting are convenient, the accuracy of alignment height.
Transmission shaft 21 is by pair of bearings 9 supportings; Transmission shaft 22 is by pair of bearings 19 supportings; Output shaft 21 is by pair of bearings 28 supportings.Like this, the power of concrete mixer is exported behind above-mentioned a pair of helical bevel gear 6, a pair of cylindric spiral gear 7 and a pair of cylindric spiral gear 8 through input shaft 5 inputs, and this output shaft 23 rotates with certain speed, drives stirrer.
In order further to improve transmission efficiency, said gear adopts superior alloy steel through carburizing and quenching, and roll flute is processed into the high-precision hard flank of tooth.Wherein, the gear of first pair of helical bevel gear 6 is behind mill teeth, through carbonitriding heat treatment.
The foregoing description can be done following variation, still can realize the purpose of this utility model:
1, considering the variation of velocity ratio, be not limited only to a pair ofly for the logarithm of helical bevel gear, can be more than two pairs.Equally, the cylindric spiral gear logarithm not only is confined to two pairs, can be a pair of or three pairs, even more than three pairs.
2, output shaft 5 can not adopt hollow shaft, and adopts common transmission shaft.
Below embodiment has been described in detail the utility model in conjunction with the accompanying drawings; those skilled in the art still can do many variations and modification according to above explanation; thereby; the details of describing should not constitute qualification of the present utility model, and marrow essence of the present utility model will contain protection by appended claims.
Claims (4)
1, a kind of concrete mixer speed reducer is characterized in that, includes housing, with the speed reducer input shaft link several to helical bevel gear, and that input end and described spiral awl tooth links, output terminal and speed reducer output shaft link is several to cylindric spiral gear.
2, concrete mixer speed reducer as claimed in claim 1 is characterized in that, it includes a pair of helical bevel gear.
