Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
As shown in Figure 1 and Figure 2, drive pulley of the present utility model, drive pulley 2 is fan-shaped belt wheel piece 21 by polylith and encloses and form, and polylith belt wheel piece 21 all has the arc end part 211 that fits with outer drive shafts, be meshed with outside driving belt end tooth section 212 and being used for is connected the fan-shaped mounting plate 213 that is of arc end part 211 and end tooth section 212.According to drive pulley of the present utility model, along drive pulley radially drive pulley is carried out subdivision, can obtain of the present utility model, enclosed the drive pulley 2 that forms by polylith belt wheel piece 21, simple in structure, easy to process.
As shown in Figure 3, variable-speed box of rubber-roller sheller of the present utility model, comprise for the rubber roller 5 that rubber roll is installed, the end of rubber roller 5 is arranged with chuck 1, slide on the first end face of the end of the close rubber roller 5 of chuck 1 and be provided with above-mentioned drive pulley 2, the belt wheel piece 21 of drive pulley 2 all can radially sliding along chuck 1.according to variable-speed box of rubber-roller sheller of the present utility model, slide on the first end face of chuck 1 and be provided with above-mentioned drive pulley 2, and the belt wheel piece 21 of drive pulley 2 all can radially sliding along chuck 1, when belt wheel piece 21 during along the radially sliding of chuck 1, the diameter of drive pulley 2 will change, the variation that to follow drive pulley 2 diameters by the rotating speed of the chuck 1 indirect rubber roller 5 that is connected with drive pulley 2 changes, thereby, the velocity ratio of one group or several groups rubber roller 5 changes, the rubber roll that is arranged on rubber roller 5 can be realized stepless change, change the linear velocity of speed or exchange speed rubber roll, speed change is simple, easy to adjust, and rubber roll all need not manually to change the speed rubber roll midway from beginning to load onto rubber roller 5 until complete working life, can save the operating time, enhance productivity.
Particularly, have on the first end face of chuck 1 a plurality of can be along the claw that radially slides 11 of chuck 1, belt wheel piece 21 is fixed with claw 11 one by one by screw or bolt, when being fixed to belt wheel piece 21 on claw 11, mounting plate 213 on belt wheel piece 21 is fitted with the upper surface of claw 11, and the end tooth section 212 on belt wheel piece 21 is away from rubber roller 5.When adopting pneumatic wrench or hand-operated tools to make claw 11 along the radially sliding of chuck 1, because belt wheel piece 21 is fixing with claw 11, therefore belt wheel piece 21 will be followed claw 11 radially sliding along chuck 1, because chuck 1 has self centering characteristics, therefore what drive pulley 2 will be along chuck 1 radially does the self-alignment campaign, change within the specific limits the diameter of drive pulley 2, the final rotating speed that changes rubber roller 5, make rubber roll realize stepless change, change the linear velocity of speed or exchange speed roller, finally obtain rational linear speed poor.
In conjunction with Fig. 3, Fig. 4 and shown in Figure 5, in order to improve drive pulley 2 along the reliability that radially slides of chuck 1, avoid drive pulley 2 to skid off chuck 1, therefore sheathed chuck back-rest cover 3 on rubber roller 5, chuck back-rest cover 3 is the dome shape, and chuck 1 and drive pulley 2 all are positioned at the dome of chuck back-rest cover 3.When drive pulley 2 to away from the central slide of chuck 1 time, end tooth section 212 on drive pulley 2 will with the inwall butt of chuck back of the body cover by 3 cover mouth place, as shown in Figure 5, thereby rely on the effect of chuck back-rest cover 3, can limit drive pulley 2 and slide in the dome of chuck back-rest cover 3, improve the reliability of drive pulley 2 motions.
Preferably, as shown in Figure 6, the center of chuck back-rest cover 3 has protrudes towards drive pulley 2, and the sleeve part 31 that is sleeve-shaped, sleeve part 31 is sheathed on rubber roller 5, sleeve part 31 is connected with rubber roller 5 by the flat key that is arranged on rubber roller 5, and chuck 1 is set on the outer circumferential face of sleeve part 31.Comparing chuck 1 directly is installed on rubber roller 5, both have relative movement trend due to chuck 1 and rubber roller 5, therefore easily wear and tear in chuck 1 and rubber roller 5 both contacted positions, affect transmission accuracy, when when chuck 1 and 5 of rubber rollers are set up sleeve part 31, chuck 1 is connected indirectly with rubber roller 5, reduces the wearing and tearing of chuck 1 and rubber roller 5, improves both transmission accuracy and working life.
as Fig. 4, Fig. 7, Fig. 8 and shown in Figure 9, in order to improve drive pulley 2 along the reliability that radially slides of chuck 1, avoid drive pulley 2 and rubber roller 5 to move to axial and circumferentially rotate, therefore on the end face of the close drive pulley 2 of rubber roller 5, pressing plate in the form of annular discs 4 is set, has a plurality of outwardly lug 41 of arranging along its circumference on the outer circumferential face of pressing plate 4, and offer be used to the groove 214 that holds lug 41 between adjacent two belt wheel pieces 21, by fixed blocks such as screw or bolts, lug 41 is fixed on chuck 1, simultaneously, pressing plate 4 is fixing with rubber roller 5 and chuck 1, and then further increase the reliability of rubber roller 5 and chuck 1 transmission.
As can be seen from the above description, the utility model the above embodiments have realized following technique effect:
Drive pulley of the present utility model, along drive pulley radially drive pulley is carried out subdivision, can obtain of the present utility modelly, enclose by polylith belt wheel piece the drive pulley that forms, simple in structure, easy to process; Variable-speed box of rubber-roller sheller of the present utility model, be equiped with chuck on rubber roller, the belt wheel piece of drive pulley and the claw on chuck are fixed one by one, by adopting pneumatic wrench or hand-operated tools to make claw radially sliding along chuck, thereby make drive pulley radially do the self-alignment campaign along chuck, change within the specific limits the diameter of drive pulley, the final rotating speed that changes rubber roller, make rubber roll realize stepless change, change the linear velocity of speed or exchange speed roller, speed change is simple, easy to adjust.
The above is only preferred embodiment of the present utility model, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
