Description
Technical field
The utility model relates to a kind of speed reducer, relates in particular to a kind of speed reducer with safety braking functions.Belong to the retarder technical field with safety brake.
Background technique
Speed reducer plays coupling rotating speed and transmitting torque between prime mover and working machine or actuator, and in modern mechanical, application is very extensive.
Existing speed reducer, be divided into safety braking functions and not with two kinds of safety braking functions, with safety brake, speed ratio is just generally less, energy consumption is higher; As want energy consumption low, general speed ratio is just large, is not with safety brake.As low again with the requirement of safety brake in reached energy consumption, certainly will there is the problems such as complex structure, processing difficulties, volume are large, Heavy Weight, manufacture cost height.
Summary of the invention
The utility model technical issues that need to address are, the speed reducer with safety braking functions of prior art, or speed ratio is little, and energy consumption is high; Or complex structure, processing difficulties, volume are large, Heavy Weight, manufacture cost are high.
The utility model is taked following technological scheme: a kind of speed reducer with safety brake comprises live axle, casing, ring gear, planetary gear set, poor tooth sun gear, poor tooth planetary gear set, poor tooth transmission ring gear, box cover; Described ring gear is fixed on box house, the planetary pinion engagement of its internal tooth and planetary gear set, and planetary pinion and live axle engagement, also coordinate with planetary carrier, the axis gear ring of planetary carrier and poor tooth sun gear engagement; Described poor tooth sun gear also coordinates with poor tooth planetary gear set, described poor tooth planetary gear set and the interlock of poor tooth transmission ring gear, and described poor tooth transmission ring gear has the internal spline axis hole; Described box cover and casing are fixed, and its central axis hole is corresponding with described internal spline axis hole.
When the speed reducer of the utility model band safety brake is worked, by turning round on the internal gear of gear driven planetary gear set on ring gear on live axle, the planetary carrier outer panel band moment tooth sun gear of planetary gear set also turns round on the internal tooth of ring gear with poor tooth planetary gear set, differ from the tooth planetary gear set and drive again poor tooth transmission ring gear running, the driving force of speed reducer is that the internal spline axis hole by differing from tooth transmission ring gear passes.Because being is provided with poor tooth drive mechanism, by poor tooth transmission ring gear, realized the function of safety brake.
Further, described poor tooth planetary gear set comprises poor tooth planetary pinion and two poor tooth planetary carriers.
Further, described poor tooth planetary pinion part coordinates with ring gear, and part coordinates with poor tooth transmission ring gear.
The beneficial effects of the utility model are:
1) possesses safety braking functions.
2) compact structure, volume is little, lightweight, and energy consumption is low.
3) process easyly, cost of production is low.
The accompanying drawing explanation
Fig. 1 is the axis sectional view of the speed reducer of the utility model band safety brake.
Fig. 2 is the axis sectional view of each component of speed reducer of the utility model band safety brake.
Wherein, 1, live axle, 2, casing, 3, ring gear, 4, planetary gear set, 5, poor tooth sun gear, 6, poor tooth planetary gear set, 7, poor tooth transmission ring gear, 8, box cover.
Embodiment
Below in conjunction with specific embodiment, the utility model is further illustrated.
Referring to Fig. 1-Fig. 2, the utility model speed reducer comprises live axle 1, casing 2, ring gear 3, planetary gear set 4, poor tooth sun gear 5, poor tooth planetary gear set 6, poor tooth transmission ring gear 7, Box Cover slope 8.
Referring to Fig. 2, be provided with many mounting grooves 201 and Box Cover panel seat 202 in casing 2, ring gear 3 is provided with many raised line 302 and internal tooth is installed, mounting groove 201 in casing combines with the corresponding raised line 302 of installing of ring gear 3, the internal tooth of ring gear 3 matches with planetary gear set 4, planetary gear set 4 matches with the gear on live axle 1, and the internal tooth of ring gear 3 matches with poor tooth planetary gear set 6.
Planetary carrier outer panel 403 matches with poor tooth sun gear 5, poor tooth sun gear 5 matches with poor tooth planetary gear set 6, poor tooth transmission ring gear 7 is provided with poor tooth transmission internal gear 701 and poor tooth transmission internal spline axis hole 702, the poor tooth transmission internal gear 701 of poor tooth transmission ring gear 7 matches with poor tooth planetary gear set 6, and box cover 8 matches with Box Cover panel seat 202.
During the work of the utility model speed reducer, by turning round on the internal tooth of gear driven planetary gear set 4 on ring gear 3 on live axle 1, the planetary carrier outer panel 403 of planetary gear set 4 turns round on the internal tooth of ring gear 3 with moment tooth sun gear 5 and with poor tooth planetary gear set 6, poor tooth planetary gear set 6 drives again poor tooth transmission ring gear 7 runnings, the driving force of gearbox is that the internal spline axis hole 702 by differing from tooth transmission ring gear 7 passes, and realizes deceleration.
