Abstract
The utility model relates to a stepless gearing device which is composed of a wheel shaft 1, a left fixed wheel 2, a right fixed wheel 3, a sliding wheel 4, a rotating sleeve 5, a seat body 6, a rotating rod 7, an operating rod 8, and a pin shaft 9, wherein, the rotating sleeve 5 is arranged on the wheel shaft 1, the left fixed wheel 2 and the right fixed wheel 3 are fixed on the rotating sleeve 5, the sliding wheel 4 is arranged between the left fixed wheel 2 and the right fixed wheel 3, the wheel shaft 1 is fixed to the rotating rod 7, one end of the rotating rod 7 is connected with the operating rod 8, and the other end of the rotating rod 7 is connected with the seat body 6 through the pin shaft 9. The rotating rod 7 can rotate around the pin shaft 9. The seat body 6 is provided with a waist-shaped long groove 10, and the operating rod 8 is clamped in the waist-shaped long groove. The utility model has the advantages of simple structure, adjustable speed, and convenient operation.
Description
The utility model relates to a kind of stepless speed changes devices.
Existing stepless speed changes devices generally all adopts friction wheeled, and the abrasion of this mode complex structure is big, and Operation and maintenance are all extremely inconvenient.
The purpose of this utility model is to provide a kind of stepless speed changes devices simple in structure.
The utility model is simple in structure, and speed is adjustable arbitrarily, and is easy to operate.
Below in conjunction with accompanying drawing its structure is further described
Fig. 1 is a main sectional view of the present utility model
Fig. 2 is a side view of the present utility model
Fig. 3 is a transmission schematic representation of the present utility model
Fig. 4 is the plan view of left and right fast pulley of the present utility model
Fig. 5 is the sectional view of left and right fast pulley of the present utility model
Fig. 6 is the plan view of movable pulley of the present utility model
Fig. 7 is the sectional view of movable pulley of the present utility model
The utility model is by wheel shaft 1, left fast pulley 2, right fast pulley 3, movable pulley 4, turning set 5, pedestal 6, dwang 7, control stick 8, bearing pin 9 forms, and turning set 5 is installed on the wheel shaft 1 by bearing, can rotate around wheel shaft 1,3 of left fast pulley 2 and right fast pulleys are fixed on the turning set 5, between left fast pulley 2 and right fast pulley 3 movable pulley 4 is housed, movable pulley 4 can slide left fast pulley 2 at left fast pulley 2 with between fast pulley 3, right fast pulley 3, movable pulley 4 can rotate around wheel shaft 1 with turning set 5,1 on wheel shaft is fixed on the dwang 7, one end of dwang 7 is connected with control stick 8, and the other end links to each other with pedestal 6 by bearing pin 9, and dwang 7 and bearing pin 9 are movingly, but bearing pin 9 rotates, and has kidney-shaped at pedestal 6 Elongated slot 10, control stick 8 is stuck in the kidney-shaped elongated slot, be provided with engaging tooth 11 at left fast pulley 2 and right fast pulley 3, on movable pulley 4, also be provided with engaging tooth 12, when movable pulley 4 when turning set 5 slides, can only with 3 engagements of left fast pulley 2 or right fast pulley, like this, movable pulley 4 and turning set 5, left fast pulley 2, right fast pulley 3 rotate together, can not rotate separately.
When using the utility model, cover is loaded onto V belt 13 between left fast pulley 2 and movable pulley 4 earlier, the other end of V belt 13 is sleeved on the belt pulley of prime mover 14, cover is loaded onto V belt 15 between right fast pulley 3 and movable pulley 4 again, the other end of V belt 15 is sleeved on the belt pulley of working machine 16, consist of belt pulley A between so left fast pulley 2 and the movable pulley 4, consist of belt pulley B between right fast pulley 3 and the movable pulley 4, prime mover 14 drives belt pulley A by V belt 13 and rotates, because belt pulley A and belt pulley B are connected in one, belt pulley B drives working machine 16 by V belt 15 again and rotates, when working machine 16 need build up speed, promote control stick 8 to the right, control stick 8 and dwang 7 all turn right around bearing pin 9, belt 13 is tightened up like this, 15 of belts are loose, and moving right at the effect downslide driving wheel 4 of belt force progressively reduces the radius of belt pulley A, and the radius of belt pulley B progressively increases, so just strengthen the speed of working machine, otherwise then can reduce the speed of working machine.
The utility model promotes control stick and has changed prime mover 14 and A wheel when speed change, the centre-to-centre spacing between working machine 16 and the B wheel, but because A, the variation of B wheel diameter makes the length of belt not need to change.
