Abstract
The utility model discloses a combined belt wheel for a secondary belt drive. The combined belt wheel for the secondary belt drive comprises small belt wheels and a big belt wheel, the small belt wheels are symmetrically arranged on the two sides of the big belt wheel, and the small belt wheels and the big belt wheel are cast to be a whole. The combined belt wheel for the secondary belt drive is arranged on a shaft, and therefore the stress state of the shaft and a bearing is improved, and the structure is made to be more compact.
Description
Technical field
The utility model relates to the Combined belt wheel that a kind of second belt transmission is used, and belongs to the belt transmission technical field.
Background technique
Belt transmission particularly V is with transmission due to simple in structure, cost is low, is used widely on many equipment, and the bel-drivenn maximum transmission ratio generally should not surpass 5, if velocity ratio is greater than 5, some equipment just needs to adopt the second belt transmission to reach the deceleration requirement.Namely the follower of the driving wheel of the first axle (small pulley) and the second axle (large belt wheel) is with by V and is formed the one-level belt transmission; The follower of the driving wheel of the second axle (small pulley) and the 3rd axle (large belt wheel) is with by V and is formed the second belt transmission.Driving wheel (small pulley) and follower (large belt wheel) can be installed on the second axle simultaneously, and two belt pulleys arrange vertically, and axial distance is long, and the pressure that acts on axle differs in size, and cause two end supports shaft strength inequality.
The model utility content
The utility model purpose is the defective that exists for prior art, and the Combined belt wheel that provides a kind of second belt transmission to use can reach compact structure, stressed uniform purpose.
The utility model adopts following technological scheme for achieving the above object: the Combined belt wheel that a kind of second belt transmission is used, comprise small pulley and large belt wheel, and the bilateral symmetry of described large belt wheel arranges small pulley, and described small pulley is cast as one with large belt wheel.
Further, the groove number of described both sides small pulley equates.
Further, the flute profile of described both sides small pulley is identical.
The beneficial effects of the utility model are, small pulley and large belt wheel are cast as one, are installed on axle, have improved the stress of axle and bearing, make structure compacter.
Description of drawings
Figure is structural representation of the present utility model.
Embodiment
As shown in the figure, the Combined belt wheel that a kind of second belt transmission is used comprises small pulley 1 and large belt wheel 2, and the bilateral symmetry of described large belt wheel 2 arranges small pulley 1, and described small pulley 1 is cast as one with large belt wheel 2.The groove number of described both sides small pulley 1 equates.The flute profile of described both sides small pulley 1 is identical.The utility model is installed on axle, has improved the stress of axle and bearing, make structure compacter.
The above is only preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
Claims (3)
1. the Combined belt wheel that the second belt transmission is used, comprise small pulley and large belt wheel, and it is characterized in that: the bilateral symmetry of described large belt wheel arranges small pulley, and described small pulley is cast as one with large belt wheel.
