Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of retarder, particularly a kind of helical gear-hypoid gear wheel decelerator.
Background technique
Retarder is the independently enclosed transmission device between prime mover and the working machine, is used for reducing rotating speed and increases torque, to satisfy the working machine requirements of one's work.The prime mover here generally is meant common motor.
At present, most popular on the market is the worm type of reduction gearing that Italian MOTOVARIO company produces, the structure of this retarder as shown in Figure 3, comprise housing, be provided with worm gear, worm screw in housing, described worm screw links to each other with the output shaft of motor, described worm gear links to each other with working machine, as the output terminal of power, also be provided with flange at the sidepiece of housing, make things convenient for the installation of this retarder by flange.The groundwork principle of this retarder is such: machine operation, output shaft begin to rotate; Output shaft rotates the rotation that drives worm screw again, and the rotation of worm screw drives the rotation of worm gear again, and worm gear rotates the work that drives working machine again.
Can it is evident that by Fig. 3 the housing height H of this worm type of reduction gearing is the length L that is slightly larger than housing, and the length L of housing is added the length N of the flange that is arranged on the housing sidepiece, can draw such formula by Fig. 3 represents: H ≈ L+N also is similar to a square with regard to the sectional view of saying whole worm type of reduction gearing.Make the structure of this worm type of reduction gearing compact more like this, the required space that accounts in the housing is also less; But also there is following defective in worm type of reduction gearing like this: 1, transmission efficiency is low; 2, heating easily; 3, the output torque is little.In addition, the worm and gear meshed gears partly adopts Cu alloy material to make, and causes user cost higher.
In order to solve the above problems, someone has designed a kind of helical teeth-conic reducer, as shown in Figure 4, this helical teeth-conic reducer comprises housing, is located at gearwheel, small gear and transmission shaft in the housing, transmission shaft is that the output shaft with motor links, and gearwheel is meshed with small gear, and gearwheel is used for outputting power, be to link to each other with a pair of bevel gears that are 90 degree between small gear and the transmission shaft, gearwheel and small gear are helical gear.Sidepiece at housing also is provided with flange, makes things convenient for the installation of this retarder by flange.
This helical teeth-conic reducer is realized slowing down by gearwheel and small gear, and comparing above-mentioned worm type of reduction gearing is to have improved transmission efficiency.But, as seen from Figure 4: small gear is the right that is positioned at gearwheel, and the shaft axis of transmission shaft is crossing with the flank of tooth of gearwheel, the height H of also just saying the housing of this retarder is less than the length L of housing, the length N that the length L of housing is added the flange that is arranged on the housing sidepiece is big more a lot of than the height H of housing, represents with simple formula: L+N＞＞H.Obviously, the sectional view of such helical teeth-conic reducer is a rectangular.Cause the space in the housing of helical teeth-conic reducer bigger like this, increased cost of production; In addition most importantly, mostly several producers all are to use above-mentioned worm type of reduction gearing on the present market, and retarder is to be used between the working machine of motor and required deceleration, space between the two is fixed, if directly replace worm type of reduction gearing with this helical teeth-conic reducer in order to improve transmission efficiency, just must adjust the space between motor and the working machine, bring great inconvenience for like this this helical teeth-conic reducer of installation, therefore, this helical teeth-conic reducer promotion and application on a large scale.
Summary of the invention
