Embodiment Construction
[0011] The reference signs in the drawings of the specification include: prime mover shaft 1, general machine output shaft 2, driving cone 3, driving belt 31, driven cone 4, driven belt 41, groove 411 on the driven belt, driving belt 5, adjusting rod 6, push block 61.
[0012] basically as figure 1 Shown: In this embodiment, it includes the frame, the adjusting rod, the transmission belt, the prime mover shaft and the output shaft of the general machine. A driving cone and a driven cone are respectively fixedly connected to the top, and the adjacent sidelines in the common longitudinal section of the driving cone and the driven cone are parallel. The driving cone and the driven cone are respectively sleeved with a driving belt and a driven belt. The driving belt and the The driven belt is slightly larger than the maximum outer diameter of the cone, and the adjusting rod parallel to the output shaft of the general machine is connected to the frame through a sliding bearing to ...

The invention discloses a speed regulation device of a low-abrasion belt type general-purpose engine, and solves the problems of low abrasion and adjustable stepless speed change which are both considered by an output shaft of the general-purpose engine in the prior art. The speed regulation device comprises a frame, a regulating rod, a transmission belt, a rim shaft and the output shaft of the general-purpose engine, wherein a drive cone and a driven cone are respectively arranged on the rim shaft and the output shaft of the general-purpose engine which are parallel, adjacent side boundaries in a common longitudinal section of the drive cone and the driven cone are parallel, the drive cone and the driven cone are respectively sleeved with a drive belt and a driven belt, the transmission belt is tightly sleeved on the outer surfaces of the drive belt and the driven belt, the regulating rod which is parallel to the output shaft of the general-purpose engine is connected to the frame in a sliding manner and has an axial movement degree of freedom, a push block used for pushing a narrow side of the transmission belt is arranged on the free end of the regulating rod, a groove matched with the cross section of the transmission belt is arranged on the outer surfaces of the drive belt and the driven belt, and the transmission belt is embedded into the groove. According to the speed regulation device, different line speed ratios of the drive side and the driven side are realized so as to achieve the stepless speed change of the output shaft of the general-purpose engine.
Description
technical field [0001] The invention relates to a speed change device which can be used for a general machine. Background technique [0002] General engines refer to gasoline engines other than vehicles and special purposes, and their rated power is generally below 30kW. It is mainly used as supporting power for agricultural and forestry plant protection machinery, small agricultural machinery, garden machinery, motor generator sets, construction machinery, outboard machinery, etc. Because of its small size, light weight, cheap price and convenient use, the general-purpose small gasoline engine occupies an important position in the matching of various machines and tools. Usually, the output shaft of the general machine is used to connect with other machines and tools. Especially among the knapsack machines, the general-purpose small gasoline engine is the only supporting power. Due to its wide application, there are also high requirements for the applicability of the gener...
