Abstract
A locking device used for moving a gear in a gear box comprises a sliding-moving gear arranged on an input shaft and capable of moving axially in a sleeved mode, and a locking block capable of falling into a corresponding groove of the input shaft, wherein the locking block and one lateral of the sliding-moving gear are connected together through a fixed pin, and a slide ring capable of pressing the locking block into the groove on the input shaft is arranged on the locking block in a sleeved mode; a check block blocking the sliding-moving gear to move in place is fixed on one side, where the groove is formed, in the input shaft; the sliding-moving gear is connected with a transmission rod through a shift block and a shift fork, and the transmission rod is connected with a lifting rod used for being operated by hand and located outside the gear box; and the shift fork is placed on an inner support of a box body of the gear box through a short shaft on the left side and a transmission shaft on the right side, and the transmission shaft stretches out the box body of the gear box and is connected with the lifting rod. The locking device used for moving the gear in the gear box has the advantages that efficiency is high, the structure is compact, the gear can reliably work in the transmit motion, and the like.
Description
Technical field
The utility model relates to a kind of locking device for carrier wheel in the gear-box, belong to the locking device of the moving device of a kind of transmission of power.
Background technique
Can adopt a cover slide device in existing deceleration or step-up gear, it adopts manual shift fork carrier wheel to carry out speed change, in the process of actual transfer power, when the axial force of shifting slide gear is large, gear is difficult to axial restraint, therefore the carrier wheel that adopts in the existing gear-box is because lacking supporting locking device, thereby affects its using effect.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provide a kind of in order to meet the need of market, realize one-machine multifunction, adaptation is under a diesel engine drives, can reach the functions of deceleration or speedup and two rotating speeds output, or change behind the diesel engine of two different rotating speeds by same speed reducer, export identical rotating speed, reduce bulk, the locking device that is used for carrier wheel in the gear-box of increasing economic efficiency.
The purpose of this utility model is finished by following technical solution, it comprises one, and be nested with on input shaft can axially movable shifting slide gear, one locking block that can fall in the input shaft respective grooves is linked togather mutually by the sidepiece of fixing pin with described shifting slide gear, is equipped with above the locking block and can compresses locking block slip ring in the set groove on input shaft.
Be fixed with one on the side of set groove on the described input shaft and stop the block that shifting slide gear moves into place, link to each other with the outside driving lever that is used for manual control of gear-box by shifting block and shift fork this drive link that links to each other with drive link on the described shifting slide gear.
Described shift fork is placed in the described gear case body on the bearing by left and right sides minor axis and transmission shaft, and transmission shaft stretches out the casing at gear-box, is connected with driving lever.
The utility model can make the axial restraint of shifting slide gear on input shaft, make shifting slide gear after slippage conversion rotating speed, and make the shifting slide gear can be at axial restraint, and can bear certain axial force, have the efficient height, compact structure makes the gear characteristics such as can work reliably in transmitting motion.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the operating principle schematic representation of sliding gear described in the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: shown in Figure 1, the utility model comprises one, and be nested with on input shaft 1 can axially movable shifting slide gear 2, one locking block 3 that can fall in input shaft 1 respective grooves is linked togather mutually by the sidepiece of fixing pin 5 with described shifting slide gear 2, is equipped with above the locking block 3 and can compresses locking block 3 slip ring in the set groove 4 on input shaft 1.
Be fixed with one on the input shaft 1 shown in the figure on the side of set groove and stop the block 6 that shifting slide gear 2 moves into place, link to each other with drive link 8 by shifting block 9 and shift fork 10 on the described shifting slide gear 2, this drive link 8 links to each other with the outside driving lever 7 that is used for manual control of gear-box, as shown in Figure 2.
The minor axis 12 of shift fork 10 shown in Fig. 2 by the left and right sides is placed in the described gear case body on the bearing 13 by straight pin 11 and drive link 8, and drive link 8 stretches out the casing at gear-box, is connected with driving lever 7.
During use, when needs move shifting slide gear 2, pull driving lever 7 and move, when shifting slide gear 2 moved to certain position, locking block 3 fell in the groove of input shaft 1 automatically, and driving lever 7 stops when continuing to move to block 6.This moment is because the interaction of slip ring 4 and locking block 3 is locked shifting slide gear 2 in the groove of input shaft 1.
Embodiment: when shifting slide gear 2 need carry out moving axially along input shaft 1, pull driving lever 7, driving lever 7 direction is on demand moved, when shifting slide gear 2 moves to certain position, locking block 3 is fallen in the groove on the input shaft 1, this moment, slip ring 4 can also continue to move, and had just stopped when slip ring moves to block 6.Because locking block 3 is linked togather by fixing pin 5 and shifting slide gear, locking block 3 is pressed on by slip ring 4 in the groove of input shaft 1 and can not moves, and at this moment, shifting slide gear 2 just has been fixed on the input shaft 1, has reached the effect of axial restraint.
Claims (3)
