Abstract

The invention discloses a differential gear box, which aims to solve the problem in the prior art that back-twist state conversion of one or multiple cradles cannot be realized during cable production. The differential gear box comprises a box body, a motor shaft, a pinion installed on one end of the motor shaft, a big gear wheel located above the pinion and engaged with the pinion, and a worm which is located above the motor shaft, parallel to the motor shaft and installed on the box body, wherein the big gear wheel is installed on the left end of the worm, a worm-wheel shaft of which the axis is perpendicular to the worm is disposed under the worm, a bearing base is installed on the middle of the worm-wheel shaft, a worm wheel engaged with the worm is installed on the bearing base, and a clutch is disposed on the front end of the worm wheel. The clutch is a double-claw clutch. When the clutch switches positions, rotation of the bearing base drives the worm-wheel shaft to rotate, or a center shaft rotates together with a gear back-twist pair. The differential gear box provided by the invention can realize the back-twist state conversion of one or multiple cradles without influencing back-twist states of the other cradles, and can still satisfy requirements for differential control without a planetary gear differential mechanism.

Further, the worm screw is from left to right sequentially installed with gear wheel, axle sleeve, check ring, worm screw left bearing and snail Bar right bearing, the worm screw left end is provided with the left end cap on casing, divides between the gear wheel left and right sides and casing Gear wheel left bearing and gear wheel right bearing are not provided with, the axle sleeve is provided with sealing ring, be easy to transmit the motion of little gear Onto worm gear.
Further, tank filler sleeve is equipped with the casing above the gear wheel and worm screw, is easy to add lubricating oil.
Further, the worm screw right bearing right-hand member is provided with bearing (ball) cover, in being fixed with the bearing (ball) cover right-hand member casing Portion is provided with the right end cap of screwed hole, and the screw for fastening bearing (ball) cover is provided with screwed hole, is moved right for limiting right bearing It is dynamic.
Further, the right end cap right-hand member is provided with the nut being enclosed within screw, and the nut serves further locking Effect.
Further, the worm-wheel shaft is sequentially provided with bearing, worm gear after rear bearing (ball) cover, rear bearing, worm-wheel shaft from back to front Axle fore bearing, bearing block and clutch, are sequentially installed with worm gear, bearing block bearing and front end from back to front on the bearing block Lid, is easy to the installation and transmission of worm gear.
Further, the clutch is double pawl clutches, and bearing block is provided with the claw type machine matched with the rear end of clutch Structure, is easy to clutch according to being changed the need for back twist.
Compared with prior art, it is an advantage of the invention that：Clutch is employed, when cable is produced, it is possible to achieve individually The back twist State Transferring of one or several cradles, the back twist state without influenceing other cradles, in no satellite differential In the case of, the present invention can also meet the requirement of Differential Control.
Brief description of the drawings
The invention will be further described below in conjunction with the accompanying drawings：
Fig. 1 is the front view of differential case；
Fig. 2 is the enlarged drawing at A；
Fig. 3 is the left view of differential case.
Specific embodiment
Refering to Fig. 1, Fig. 3, a kind of differential case, including casing 1, motor shaft 4, the little gear installed in motor shaft one end 2nd, positioned at the top of little gear 2 and engage with little gear 2 gear wheel 3, install above motor shaft 4 and parallel to motor shaft 4 Worm screw 5 on casing 1, the gear wheel 3 is arranged on the left end of worm screw 5, and the lower section of the worm screw 5 is provided with axis and is hung down with worm screw 5 Straight worm-wheel shaft 6, the middle part of the worm-wheel shaft 6 is provided with bearing block 7, and the worm gear engaged with worm screw 5 is provided with the bearing block 7 8, the front end of the worm-wheel shaft 6 is provided with clutch 9.
Refering to Fig. 1, worm screw 5 described in Fig. 2 is from left to right sequentially installed with gear wheel 3, axle sleeve 11, check ring 12, worm screw Left bearing 13 and worm screw right bearing 15, the left end of the worm screw 5 are provided with the left end cap 16 on casing 1, and the gear wheel 3 is left Gear wheel left bearing 17 and gear wheel right bearing 18 are respectively equipped between right both sides and casing 1, the axle sleeve 11 is provided with sealing Circle 19；The right-hand member of worm screw right bearing 15 is provided with bearing (ball) cover 20, middle part is fixed with the right-hand member casing 1 of the bearing (ball) cover 20 and is set There is the right end cap 21 of screwed hole, the screw 22 for fastening bearing (ball) cover 20 is provided with screwed hole；The right-hand member of the right end cap 21 sets There is the nut 23 being enclosed within screw 22；Tank filler sleeve is equipped with the casing 1 of the gear wheel 3 and the top of worm screw 5.
