Abstract
The utility model discloses an engine wheel train tensioning wheel, which comprises a tensioning wheel outer ring, a bearing retaining ring, a shaft, a bearing and a sleeve gasket. The tensioning wheel outer ring is sleeved onto the shaft through the bearing. The bearing is thrusted from the two ends thereof through the bearing retaining ring and the sleeve gasket. The shaft is provided with an eccentric nail passing hole. According to the utility model, the engine wheel train tensioning wheel adopts an eccentric wheel for adjusting the tensioning state of a belt. Therefore, the space for installing the tensioning arm of a cantilever type automatic tensioning wheel is saved. The engine wheel train tensioning wheel saves the assembly space and is small in volume, simple in structure and convenient to operate.
Description
Technical field
The utility model relates to engine art, particularly a kind of engine wheel system Idle wheel.
Background technique
What the engine wheel system tensioning mechanism adopted basically at present is cantilever type auto-tensioning wheel.Idle wheel is the tension device of band transmission, when the centre distance of band can not be regulated, can adopt Idle wheel will be with tensioning.Idle wheel generally is arranged in the inboard of slack list, thereby makes band only receive bend in one direction; Simultaneously, reduce too much for guaranteeing that the small pulley cornerite is unlikely, Idle wheel should be installed near big belt wheel as far as possible.This auto-tensioning wheel construction comprises: spring, spring seat, tension arms and roller, the lashing force of spring is delivered to front end through tension arms and compresses belt and get roller, realizes tensioning.
But the tension arms length of cantilever type auto-tensioning wheel is bigger; Make that whole Idle wheel throw is also bigger, cause the required headspace of assembling bigger, though the elongation of compensation belt is bigger; But restrictions such as small displacement engine or supporting car steering cabin; Under the situation that front end train space is very limited or the belt elongation is smaller, cantilever type auto-tensioning wheel difficult arrangement, the function of the cantilever type auto-tensioning that has wheel is superfluous.
The model utility content
The technical problem that the utility model solves provide a kind of simple in structure, volume is little, save the engine wheel system Idle wheel of assembly space.
For achieving the above object; A kind of engine wheel system Idle wheel that the utility model provides; Comprise: Idle wheel outer ring, end ring, axle, bearing and spacer; The Idle wheel outer ring installs on the axle through bearing housing, and end ring and spacer be the said bearing of thrust from two ends, offers an eccentric nail hole of crossing on the axle.
Further, the inner ring of bearing and axle interference fit, the outer ring of bearing and Idle wheel outer ring interference fit.
Further, end ring is arranged in the installation groove of Idle wheel outer ring, props up an end of bearing.
Further, spacer is sleeved on the axle, props up the other end of bearing.
Further, offer a hexagonal blind hole on the end end face of axle.
Technological scheme according to the utility model; Because this engine wheel system Idle wheel adopts eccentric wheel to adjust compressing belt; Saved the assembly space of the tension arms of cantilever type auto-tensioning wheel, volume is little, save assembly space, and is simple in structure simultaneously, be convenient to operation.

Embodiment
Below in conjunction with accompanying drawing, the embodiment of the utility model is described in detail, but the protection domain that is to be understood that the utility model does not receive the restriction of embodiment.
Referring to Fig. 1 to Fig. 3, this engine wheel system Idle wheel comprises: Idle wheel outer ring 1, end ring 2, axle 3, bearing 4 and spacer 5.Wherein, offer a center line on the axle 3 and cross nail hole 6 with the off-centre that shaft centre line does not overlap; Bearing 4 covers install on the axle 3, the inner ring of bearing 4 and axle 3 interference fit, the outer ring of bearing 4 and Idle wheel outer ring 1 interference fit; End ring 2 places Idle wheel outer ring 1 groove, to bearing 4 thrust effects, prevents that bearing 4 is along axle 3 axial slips from left end; Spacer 5 is from the right-hand member suit axle 3 of bearing 4, and to bearing 4 thrust effects, effect is equivalent to the back-up ring of bearing 4 right-hand members from right-hand member, and the right-hand member of the right-hand member projecting shaft 3 of spacer 5 is attached on the attachment face when Idle wheel is installed and plays a supportive role; The left end of axle 3 offers a common hexagonal blind hole 7, is used to utilize spanner to rotate Idle wheel to suitable tightening belt and gets the position.
During work; Fixing bolt 8 is crossed nail hole 6 through off-centre this Idle wheel is fixed on the Idle wheel bearing (not shown); Bolt need not be tightened Idle wheel fixing earlier; Making this Idle wheel around can rotating in the angular ranges at 180 degree of fixing bolt, owing to cross nail hole 6 and Idle wheel outer ring 1 disalignment, is unequal so cross the distance of each point on the center of following closely hole 6 and Idle wheel outer ring 1 cylindrical; The point midway of belt and Idle wheel outer ring 1 surface of contact is with nail hole 6 center position are also just unequal excessively during rotation; Insert hexagonal blind hole 7 rotation Idle wheels through spanner and regulate the appropriate location that this distance compresses belt with adjustment, promptly when belt is crossed pine, then transfer the point midway of big belt and Idle wheel outer ring 1 surface of contact and cross nail hole 6 center position; Otherwise, then turn the point midway of belt and Idle wheel outer ring 1 surface of contact down and cross nail hole 6 center position; It is fixing to tighten fixing bolt 8 then.
More than a disclosed specific embodiment that is merely the utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into the protection domain of the utility model.
