Abstract
The utility model discloses a speed changing and positioning device of a gear speed changing box of a rubber-roller rice husker, which is mainly composed of a gear speed changing box, a combined type slipping gear arranged in the gear speed changing box, and a main shaft with a spline arranged in the gear speed changing box and a speed changing handle. One end of the main shaft with a spline a hollow tube, a sliding mandrel is arranged in the tube, and a locating pin shaft arranged on the mandrel is matched with the slipping gear; the other end of the mandrel is provided with a positioning reed, and the positioning reed can position in a square hole of the speed changing handle. The utility model has the advantages of simple structure, reliable positioning, and safe and convenient operation. The utility model is suitable for a gear speed changing box of rubber-roller rice huskers.
Description
The utility model relates to a kind of speed-changing gear box speed varying locator of rubber roll husker.
Be used to process the rubber roll husker of grain at present, must guarantee that certain linear speed is poor during because of its two rubber rollers work, often speed exchanges speed change again, consistent in the hope of the wearing and tearing of two rubber rolls, for this reason, the gear of required supporting speed-changing gear box all adopts Lever type or rack-and-pinion class conventional design.But be subjected to the restriction on the hulling machine overall structure, the gear change hand lever that stretches out top box face or side is awkward, so, reliability of positioning is poor, mechanism's complexity, and when the gear teeth just overlap, need to move the belt pulley several angle and just can enter the engaging position with hand, not only time-consuming but also require great effort, and dangerous.
The purpose of this utility model is at above-mentioned shortcoming, designs a kind of simple in structurely, and the location is reliable, easy to operate rubber roll husker speed-changing gear box speed varying locator.
The utility model is the speed-changing gear box speed varying locator, mainly is made up of gear graduation box body and the shifting slide gear be located in the gear graduation box body, also comprises and is located at the interior speed varying locator of shifting slide gear.Described speed varying locator mainly is made up of wounded in the battle key main shaft and gear change hand lever, the part of wounded in the battle key main shaft places in the gear graduation box body, the part of exposing the gear graduation box body then is placed in the gear change hand lever, the wounded in the battle key main shaft of part that is placed in the gear change hand lever is provided with positioning reed, this positioning reed is set in the gear change hand lever square hole, one section that is placed in the interior wounded in the battle key main shaft of speed-changing gear box is hollow tube, be provided with the slip mandrel in the hollow tube, the front end of wounded in the battle key main shaft and slip mandrel is provided with alignment pin, and moving of alignment pin can make shifting slide gear form new gear pair.
The utility model compared with prior art has following distinguishing feature and progress.The one, simple in structure, this device does not account for the upper space of casing, helps the expansion of hulling machine intake grill; The 2nd, the location is reliable, and the positioning reed on the wounded in the battle key main shaft of the utility model and the setting of the square hole on the gear change hand lever make the speed change location correct reliable, has avoided the trip stop displacement when sudden load change of original gear gearbox, thus the situation that causes gear to damage.The 3rd, the utility model is easy to operate, and is safe and reliable.The utility model is applicable on the rubber roll husker speed-changing gear box and uses.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Accompanying drawing is the utility model overall structure sectional view.
As shown in the figure, the utility model is made up of gear graduation box body 5 and the shifting slide gears 1 be located in the gear graduation box body 5, speed varying locator comprises compositions such as wounded in the battle key main shaft 3 and gear change hand lever 10, the part of wounded in the battle key main shaft 3 is placed in the shifting slide gear 1 in the gear graduation box body 5, the part of exposing gear graduation box body 5 then is placed in the gear change hand lever 10, the wounded in the battle key main shaft 3 that is placed in the gear change hand lever 10 is provided with positioning reed 8, this positioning reed 8 can be positioned in the gear change hand lever square hole 9, one section that is placed in wounded in the battle key main shaft 3 in the speed-changing gear box 5 is hollow tube, be provided with slip mandrel 4 in the hollow tube, the head of slip mandrel 4 is provided with alignment pin 2, moving of alignment pin 2 can make shifting slide gear 1 horizontally slip, and forms new gear pair.The cylindrical of wounded in the battle key main shaft 3 also is provided with O type circle 7, is used for sealing, and the lubricant oil in the speed-changing gear box is not leaked.
During the position, positioning reed 8 is located in gear change hand lever square hole 9 as shown in the figure.When gear need move to another position when forming new gear pair, available finger is pressed positioning reed 8 and is pulled out gear change hand lever 10, positioning reed 8 is located in another gear change hand lever square hole 9, the distance of two gear change hand lever square holes 9 and shifting slide gear 1 move required distance and are consistent on the gear change hand lever 10, gear change hand lever 10 rotates synchronously with wounded in the battle key main shaft 3, when speed change, run into gear and overlap, only need small angle of gear change hand lever 10 rotations can be made the gear teeth back correct engagement that staggers.
The utility model is applicable on the speed-changing gear box of rubber roll husker and uses.
