Abstract
A speed variator for internal combustion engine belt pulley belongs to the internal combustion engine accessory, and is used for small motor-driven ship, tractor and agricultural automobile. The transmission is characterized by comprising a transmission shaft, a sliding transmission driving gear, a transmission driven gear, a clutch mechanism and a variable-speed transmission gear, wherein one end of the transmission shaft is connected with a flywheel and penetrates through a central shaft hole of a belt pulley, the sliding transmission driving gear is arranged at the other end of the transmission shaft, the transmission driven gear is connected with the belt pulley into a whole, the clutch mechanism is positioned between the transmission driven gear and the belt pulley, and the variable-speed transmission gear is coaxially doubly connected with one small gear. The device has the advantages of simple structure, convenient installation and use, safety, reliability, time saving, oil saving, high efficiency and the like, and can run at the original speed during heavy load and run at accelerated speed during no load.
Description
A kind of change-speed box of combustion engine belt pulley belongs to the internal combustion engine part technical field, is mainly used in the equipment of small motor ship, trac. and agricultural vehicle etc.
In the prior art, the belt pulley of combustion engine does not generally all have speed-changing mechanism.All use identical speed to travel no matter heavy duty is still unloaded like this.Both wasted fuel, and be unfavorable for again raising the efficiency, saved time.
It is a kind of simple in structure, easy to use, safe that the purpose of this utility model is to provide, the ratio transmissions of pressing belt pulley during heavy duty is promptly travelled in tempo, then can quicken when unloaded, thereby save time in transit and fuel, the change-speed box of the combustion engine belt pulley of increasing work efficiency.
According to the groundwork of change-speed box and the constructional feature of combustion engine belt pulley, at existing questions in the prior art, this uses later-model basic design to be: transmission shaft and belt pulley are roll to cooperate, and by it an end with terminal pad be connected with flywheel, install one again at the other end of this transmission shaft and be enclosed within on the axle sliding type transmission gear that rotates synchronously with axle and the driven gear and the dress that are connected as a single entity with belt pulley or be located at the pressure edge formula engaging and disengaging gear and the one little one doubly-linked change gear that can be meshed with them respectively greatly that can make their clutches between them.Even principal and subordinate's two gears lump together when needs travel in tempo like this, when needs quicken, then make this two gear leave and make pinion in driving gear and the doubly-linked gear, thereby realize design goal.
The change-speed box that this uses novel described combustion engine belt pulley is characterized in that this change-speed box is had the transmission shaft 3 of terminal pad 5 that is connected with flywheel 1 and the central shaft hole that passes belt pulley 2 by axle head, doubly-linked speed change drive pinion 7a that is loaded on the sliding type transmission gear 6 of this other end and is meshed and doubly-linked speed change transmission big gear wheel 7b and be meshed with it and be connected as a single entity and be used to drive driven gear 8 and the dress that belt pulley 2 rotates or be located at above-mentioned transmission master with above-mentioned belt pulley 2 with it, constitute from the pressure edge formula engaging and disengaging gear 9 of taking turns relatively between two gears 6 and 8 on the card.
This uses later-model advantage is simple in structure, easy to install, safe and reliable, and when heavy duty lumps together still ratio transmissions by belt pulley with sliding type transmission gear and driven gear, promptly according to original design-calculated speed enforcement; And can make the faster rotational speed of belt pulley by pressing edge formula engaging and disengaging gear the sliding type transmission gear is separated with driven gear and the big miniature gears of doubly-linked speed change is meshed with them respectively when unloaded, not only can accelerate to travel, save the time in transit, but also can fuel saving, reduce operating cost, increase work efficiency.
Accompanying drawing is not intended to for this uses one of novel most preferred embodiment assembling back complete machine clutch vertical vertical profile side-looking of running condition structure.
To use later-model architectural feature to further describe this as follows with most preferred embodiment in conjunction with the accompanying drawings: adorn a transmission shaft that is connected with combustion engine 3 by antifriction-bearing box 4 in the central shaft hole of tractor engine belt pulley 2, this end of 3 has a terminal pad 5 and by it flywheel 1 is installed, this other end of 3 is installed a sliding type transmission gear 6 by spline and is enclosed within that axle is gone up and is connected as a single entity in order to drive the transfer driven gear 8 that belt pulley rotates with above-mentioned belt pulley 2, main at this, be provided with respectively and two take turns three melons that card is connected as a single entity and press edge formula engaging and disengaging gear 9 from relative wheel card between two transmission gears 6 and 8, speed change transmission big gear wheel 7b and miniature gears 7a that coaxial doubly-linked small one and large one and above-mentioned respectively driven gear 8 and driving gear 6 are meshed also are housed below this two principals and subordinates transmission gear 6 and 8.
Change as present embodiment:
1, can install 1～3 grade of doubly-linked change-gear set again additional, make it to become multi-change speed;
2, driven gear and variable gear can be dwindled and be loaded in the belt pulley, make it lighter.
Claims (2)
1, a kind of change-speed box of combustion engine belt pulley, it is characterized in that this change-speed box is had the transmission shaft [3] of terminal pad [5] that is connected with flywheel [1] and the central shaft hole that passes belt pulley [2] by its axle head, be loaded on the sliding type transmission gear [6] of this other end and doubly-linked speed change drive pinion [7a] that is meshed with it and doubly-linked speed change transmission big gear wheel [7b], and be meshed with it and be connected as a single entity and be used to drive the driven gear [8] that belt pulley [2] rotates and be installed in above-mentioned transmission master with above-mentioned belt pulley [2], constitute from the pressure edge formula engaging and disengaging gear [9] of taking turns relatively on the card between two gears [6] and [8].
2, the change-speed box of combustion engine belt pulley according to claim 1 is characterized in that in the axis hole of above-mentioned belt pulley [2] bearing [4] being housed also.
