Abstract
The utility model discloses a spiral bevel gear speed reducer, including organism, motor, spiral bevel gear, transmission shaft and output shaft, a drive gear of transmission shaft one end, the 2nd drive gear of the transmission shaft other end, set up on the output shaft and with the 2nd drive gear engaged with output gear, the both ends of output shaft with it holds all to be provided with one -way shaft between the organism, the both ends of output shaft with still be provided with tapered roller bearing between the organism. The utility model has the advantages of it is following and effect: when the motor stops, setting up one -way shaft through the both ends at the output shaft and hold for the output shaft can only carry out unidirectional rotating, and pivot that so as to avoided spiral bevel gear speed reducer to drive its linkage when stopping leads to the fact upside down or in the same direction as smooth phenomenon, still is provided with tapered roller bearing simultaneously on the output shaft, bears relatively poorly because of one -way shaft holds the radial force, can be used to supplementary one -way shaft and holds and bear the radial force through setting up tapered roller bearing.
Description
Technical field
The utility model is related to reductor field, more particularly to a kind of spiral bevel gear speed reducer.
Background technology
Reductor is generally used for the drive apparatus of low rotation speed large torque, motor, internal combustion engine or other run up
Gear wheel on the few gear engagement output shaft of the number of teeth on input shaft that power passes through reductor is general reaching the purpose of deceleration
Logical reductor also have it is several preferable slowing effect is reached to same principle gear, the ratio of the number of teeth of big little gear is exactly passed
Dynamic ratio.
At present, Authorization Notice No. is CN204664308U on market, and the day for announcing is that in September, 2015 Chinese patent of 23 days is public
A kind of spiral bevel gear speed reducer is opened, with motor, body, the two ends of described body are equipped with end cap, and end cap is provided with
Abat-vent, motor is provided with input shaft, and input shaft is provided with input gear, input gear with screw conic tooth is arranged on by flat key
First gear engagement on wheel shaft, spiral bevel gear axle and spiral bevel gear gear motion, spiral bevel gear is installed by flat key
It is fixed on gear shaft, gear shaft is by the gear gear motion that is arranged on output shaft.Simple structure, it is easy to use, simple,
Noise is little, and energy loss is little during use, and high working efficiency, structure design is compact, long service life, and installs or removes more
Plus it is convenient.
Although the characteristics of this spiral bevel gear speed reducer has rationally compact drive mechanism, high working efficiency, while energy
Forward and reverse rotation is enough realized, but during actual use, in order to avoid motor helical bevel gear drives it when stopping
The rotating shaft of linkage causes to reverse or smooth phenomenon, by arranging holdback decelerator can be caused to carry out one-directional rotation,
But need installation holdback more to bother to a certain extent in use.
Utility model content
The purpose of this utility model is to provide a kind of spiral bevel gear speed reducer, by arranging unilateral bearing in reductor
To realize the one-directional rotation of reductor.
Above-mentioned technical purpose of the present utility model technical scheme is that:A kind of spiral bevel gear subtracts
Fast machine, including body, motor, the spiral bevel gear being arranged on the motor shaft of the motor, the biography that is arranged in the body
Moving axis and output shaft, the first travelling gear for being arranged on described power transmission shaft one end and being meshed with the spiral bevel gear, set
Put the second travelling gear on the power transmission shaft other end, be arranged on the output shaft and with the second travelling gear phase
The output gear of engagement, is provided with unilateral bearing between the two ends of the output shaft and the body, and the two of the output shaft
Taper roll bearing is additionally provided between end and the body.
By adopting such scheme, by arranging unilateral bearing at the two ends of output shaft so that output shaft can only carry out list
To rotation.When motor works, drive spiral bevel gear to be rotated by motor shaft, mutually nibbled with spiral bevel gear by driving
The first travelling gear for closing drives power transmission shaft to be rotated, by the second travelling gear on the power transmission shaft other end and output
Output gear on axle is meshed, and output shaft can be driven to be rotated, and can finally drive process equipment normally to be grasped
Make;When motor stops, by arranging unilateral bearing at the two ends of output shaft so that output shaft can only carry out one-directional rotation, from
And spiral bevel gear speed reducer can be avoided to drive the rotating shaft of its linkage to cause to reverse or smooth phenomenon when stopping, while
Taper roll bearing is additionally provided with output shaft, because unilateral bearing radial load bears poor, can by arranging taper roll bearing
For aiding in unilateral bearing to bear radial load.Because taper roll bearing is mainly used to bear the radial direction and axle based on radial load
To joint load, axial load typically should not be individually born.Therefore by being provided with taper roll bearing in output shaft both sides,
Two taper roll bearings need to be oppositely arranged, when two taper roll bearings bear radial load, one of circular cone rolling
Sub- bearing will produce an axial thrust load, and another taper roll bearing produces an axially opposite component, is finally able to
Balance.
