Abstract
The invention relates to a speed reducer for a heavy-duty vehicle. A driving shaft (1) is provided with a driving gear (6), one end of the driving shaft (1) is arranged on a gearbox (4), the other end of the driving shaft (1) is arranged on a gearbox cover (5), a driven shaft (12) is arranged on the gearbox cover (5), a driven gear (2) is arranged on the driven shaft (12) by a fixed plug screw (10) and a conehead screw rod (11), a planetary frame (8) is connected with the driven shaft (12) and provided with a planetary gear shaft (9), a planetary gear (7) is arranged on the planetary gear shaft, the driven gear (2) is meshed with the driving gear (6) and the planetary gear (7) respectively, the gearbox cover (5) is arranged on the gearbox (4), a gear ring (3) is arranged on the gearbox cover (5) and meshed with the planetary gear (7). By adopting the secondary speed reduction mechanism, the speed reducer has large speed reduction ratio, large output torque, and can meet the requirements of multiple operation functions such as bulldozing, hoisting, excavation and the like.
Description
Technical field
The present invention relates to a kind of speed changer, be specifically related to a kind of retarder for heavy vehicle.
Background technique
The effect of speed reducer mainly reduces the output of motor and improves the output of motor.And the rotating speed of motor or diesel engine is generally discrepant with our rotating speed of needs, output speed is all very high, in order to obtain rotating speed or the torque of needs, needs the rotating speed of power source to reduce.
Speed reducer, as afterbody speed reducer in power train, is used for reducing rotating speed further, increases output shaft torque.Original endless-track vehicle side speed reducer adopts one-level side speed reducer, and the deceleration that it realizes is smaller, can not meet the requirement that existing vehicle realizes the several work function large torque outputs such as soil-shifting, lifting, excavation.
Summary of the invention
Technical problem to be solved by this invention is the retarder for heavy vehicle, and this retarder adopts two reduction gear, and rotating ratio is large, exports torque large.
Technological scheme of the present invention: a kind of retarder for heavy vehicle, it comprises driving shaft, driven gear, gear ring, gear-box, gear box cover, driving gear, planetary pinion, planetary frame, planet pin, fixing plug screw, conehead screw rod and driven axle, driving shaft is provided with driving gear, one end of driving shaft is arranged on gear-box, the other end is arranged on gear box cover, driven axle is arranged on gear box cover, driven gear is by fixing plug screw, conehead screw rod is arranged on driven axle, planetary frame is connected with driven axle, planetary frame is provided with planet pin, planetary pinion is arranged on planet pin, driven gear respectively with driving gear, planetary pinion engages, gear box cover is arranged on gear-box, gear ring is arranged on gear box cover, gear ring engages with planetary pinion.
Described gear-box is provided with breathing pipe, oil filler, fuel outlet, oil filler and fuel outlet are respectively arranged with plug screw.
The present invention compared with prior art has following beneficial effect: 1, the present invention adopts the two reduction gear of the outer gearing of one-level dead axle and primary planet transmission combination, reduction speed ratio is large, output torque is large, can meet the requirement of the several work functions such as soil-shifting, lifting, excavation.2, quality is light, and compact structure, anufacturability is good.3, repairing, maintenance, easy maintenance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
A kind of retarder for heavy vehicle, as shown in Figure 1, it comprises driving shaft 1, driven gear 2, gear ring 3, gear-box 4, gear box cover 5, driving gear 6, planetary pinion 7, planetary frame 8, planet pin 9, fixing plug screw 10, conehead screw rod 11 and driven axle 12, driving shaft 1 is provided with driving gear 6, one end of driving shaft 1 is arranged on gear-box 4, the other end is arranged on gear box cover 5, driven axle 12 is arranged on gear box cover 5, driven gear 2 is by fixing plug screw 10, conehead screw rod 11 is arranged on driven axle 12, planetary frame 8 is connected with driven axle 12, planetary frame 8 is provided with planet pin 9, planetary pinion 7 is arranged on planet pin 9, driven gear 2 respectively with driving gear 6, planetary pinion 7 engages, gear box cover 5 is arranged on gear-box 4, gear ring 3 is arranged on gear box cover 5, gear ring 3 engages with planetary pinion 7.
Described gear-box 4 is provided with breathing pipe, oil filler, fuel outlet, oil filler and fuel outlet are respectively arranged with plug screw.The setting of breathing pipe, makes the air circulation that gear-box is inside and outside, avoids the leakage of oil because the pressure in case raises.
Claims (2)
1., for a retarder for heavy vehicle, it comprises driving shaft (1), driven gear (2), gear ring (3), gear-box (4), gear box cover (5), driving gear (6), planetary pinion (7), planetary frame (8), planet pin (9), fixing plug screw (10), conehead screw rod (11) and driven axle (12), it is characterized in that driving shaft (1) is provided with driving gear (6), one end of driving shaft (1) is arranged on gear-box (4), the other end is arranged on gear box cover (5), driven axle (12) is arranged on gear box cover (5), and driven gear (2) is by fixing plug screw (10), conehead screw rod (11) is arranged on driven axle (12), planetary frame (8) is connected with driven axle (12), planetary frame (8) is provided with planet pin (9), planetary pinion (7) is arranged on planet pin (9), driven gear (2) respectively with driving gear (6), planetary pinion (7) engages, and gear box cover (5) is arranged on gear-box (4), and gear ring (3) is arranged on gear box cover (5), and gear ring (3) engages with planetary pinion (7).
2. the retarder for heavy vehicle according to claim 1, is characterized in that described gear-box (4) is provided with breathing pipe, oil filler, fuel outlet, oil filler and fuel outlet is respectively arranged with plug screw.
