Abstract
The utility model discloses an automatic tension pulley, which comprises a belt pulley (1), and a supporting plate (2) for connecting the belt pulley (1), a torsion spring supporting sleeve (3) installed on the supporting plate (2), a torsion spring (4) installed between the supporting plate (2) and the torsion spring supporting sleeve (3), and a position pin (5) on the external side of the supporting plate (2), wherein the belt pulley (1) is of inverted T shape, the supporting plate (2) has a pivot sleeve (6) provided therein, a cover plate (8) is in riveted joint with one end of the supporting plate (2), a grind reducing copper sleeve (10) is provided on the belt pulley (1) and the supporting plate (2) and is fixed via bolts (11). The automatic tension pulley disclosed in the utility model is advantageous in that a contact point for a chain and a tension pulley are added, swing in a scope is allowed, movement is more stable, and, automatic tensioning of the chain can be realized when the position pin arranged is taken off.
Description
Technical field
The utility model relates to a kind of mechanical transmission, particularly a kind of automatic type Idle wheel.
Background technique
In some small-sized mechanical transmission, chain drive applications is comparatively general, need the slack side of installation tensioner in transmission, reliably effective to guarantee chain-driven, but traditional tension device is circular Idle wheel to be installed realize, but the point of contact of chain and circular Idle wheel is relative less, and transmission efficiency is lower, and it is discontinuous to move.
The model utility content
The purpose of this utility model promptly is to overcome the shortcoming of existing automatic type Idle wheel, a kind of chaindriven automatic type Idle wheel that is specially adapted to is provided, replace traditional circular Idle wheel, use the Idle wheel of novel being " protruding " shape, increase the point of contact of chain and Idle wheel, swing within the specific limits, it is comparatively steady to move, simultaneously, the locating stud that takes off setting can be realized the auto-tensioning of chain automatically.
The purpose of this utility model is achieved through the following technical solutions: a kind of automatic type Idle wheel, the support plate that comprises belt pulley and connecting belt wheel, described support plate is provided with the torsion spring supporting sleeve, between support plate and the torsion spring supporting sleeve torsion spring is installed, the support plate outside has locating stud, belt pulley to be " protruding " shape.
Central axle sleeve has been installed in riveted joint in the described support plate, between central axle sleeve and support plate bearing has been installed, and an end of support plate is also riveted cover plate has been installed.
Between described support plate and torsion spring, between support plate and cover plate anti-wear gasket is installed all.
Described belt pulley and support plate are provided with the anti-attrition copper sheathing, and pass through bolt.
Gain effect of the present utility model shows: the Idle wheel that uses novel being " protruding " shape, replaced traditional circular Idle wheel, increased the point of contact of chain and Idle wheel, can swing within the specific limits, it is more steady to move, simultaneously, the locating stud that takes off setting can have been realized being specially adapted to small-sized chain-driven by the auto-tensioning of chain automatically.

Embodiment
Below in conjunction with accompanying drawing the utility model is used to be further described, but that protection domain is not limited to is described.
As Fig. 1, Fig. 2, a kind of automatic type Idle wheel, the support plate 2 that comprises belt pulley 1 and connecting belt wheel 1, described support plate 2 is provided with torsion spring supporting sleeve 3, torsion spring 4 is installed between support plate 2 and the torsion spring supporting sleeve 3, there is locating stud 5 in support plate 2 outsides, belt pulley 1 is " protruding " shape, central axle sleeve 6 has been installed in riveted joint in the described support plate 2,2 of central axle sleeve 6 and support plates have been installed bearing 7, and an end of support plate 2 is also riveted cover plate 8 has been installed, 4 of described support plate 2 and torsion springs, 8 of support plate 2 and cover plates all are equipped with anti-wear gasket 9, described belt pulley 1 and support plate 2 are provided with anti-attrition copper sheathing 10, and fixing by bolt 11.
As Fig. 3, be the motion schematic representation of prior art in the chain-driven, chain and traditional circular belt pulley point of contact are less.
As Fig. 4, be motion schematic representation of the present utility model, chain obviously contacts increase with the point of contact of belt pulley 1, and transmission is more steady.
