Abstract
The invention discloses a driving belt speed changing mechanism. The driving belt speed changing mechanism comprises a driving shaft, wherein a first belt wheel and a second belt wheel are mounted on the driving shaft, the first belt wheel is connected with the driving shaft through a first bearing, the second belt is connected with the driving shaft through the second bearing, a shifting connecting rod is mounted in the driving shaft, a sliding claw is mounted on the shifting connecting rod, a first clamping trough clamped with the sliding claw is formed in the first belt wheel, and a second clamping trough clamped with the sliding claw is formed in the second belt wheel. Therefore, the driving belt speed changing mechanism is high in driving efficiency, low in noise, unlikely to wear and convenient to maintain.
Description
Technical field
The present invention relates to field of mechanical technique, particularly relate to a kind of transmission belt speed change mechanism.
Background technology
China rural area is extensively for farm machinery, and its wheel box majority comprises walking Power output and farm implements Power output. But the wheel box majority on market is gear shift case, its noise ratio used is relatively big, and damages than being easier to.
Summary of the invention
It is an object of the invention to provide a kind of transmission belt speed change mechanism, have transmission efficiency height, noise is little, feature not easy to wear, easy to maintenance.
In order to achieve the above object, the technical scheme of the present invention is: a kind of transmission belt speed change mechanism, comprise transmission shaft, described transmission shaft is installed the first belt pulley and the 2nd belt pulley, described first belt pulley is connected with transmission shaft by the first bearing, described 2nd belt pulley is connected with transmission shaft by the 2nd bearing, fork shift connecting rod is installed in described transmission shaft, described fork shift connecting rod is provided with sliding pawl, described first belt pulley is offered and the first card groove that sliding pawl fastens, described 2nd belt pulley is offered the and card groove that fasten with sliding pawl.
Described fork shift connecting rod, by fork shift mount pad and fork shift cylinders, is provided with the 3rd bearing between described fork shift mount pad and fork shift connecting rod.
The invention has the beneficial effects as follows: the present invention is by comprising transmission shaft, described transmission shaft is installed the first belt pulley and the 2nd belt pulley, described first belt pulley is connected with transmission shaft by the first bearing, described 2nd belt pulley is connected with transmission shaft by the 2nd bearing, fork shift connecting rod is installed in described transmission shaft, described fork shift connecting rod is provided with sliding pawl, described first belt pulley is offered and the first card groove that sliding pawl fastens, described 2nd belt pulley is offered the and card groove that fasten with sliding pawl. Thus reaching transmission efficiency height, noise is little, effect not easy to wear, easy to maintenance.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Embodiment
Embodiment 1
A kind of transmission belt speed change mechanism as shown in Figure 1, comprise transmission shaft 1, described transmission shaft 1 is installed the first belt pulley 2 and the 2nd belt pulley 3, described first belt pulley 2 is connected with transmission shaft 1 by the first bearing 4, described 2nd belt pulley 3 is connected with transmission shaft 1 by the 2nd bearing, in described transmission shaft 1, fork shift connecting rod 5 is installed, described fork shift connecting rod 5 is provided with sliding pawl 6, described first belt pulley 2 is offered and the first card groove 7 that sliding pawl 6 fastens, described 2nd belt pulley 3 is offered the and card groove 8 that fasten with sliding pawl 6.By promoting fork shift connecting rod 5 to make transmission shaft 1 and the first belt pulley 2 or the 2nd belt pulley 3 card close, the linear velocity of pulley belt is certain, by the diameter variable of the first belt pulley 2 and the 2nd belt pulley 3, reaches the rotating speed changing transmission shaft 1. Thus making whole speed change mechanism reach transmission efficiency height, noise is little, not easy to wear, the effect of maintenance side.
Described fork shift connecting rod 5 is connected with fork shift cylinder 10 by fork shift mount pad 9, is provided with the 3rd bearing 11 between described fork shift mount pad 9 and fork shift connecting rod 5. Thus control speed change by cylinder.
