Abstract
The invention discloses a durable belt type general machine speed adjusting device and aims at solving the problems of low abrasion, adjustable and stepless speed change taken into account of a general machine output shaft in the prior art. The durable belt type general machine speed adjusting device comprises a frame, an adjusting rod, a transmission belt, a rim shaft and a general machine output shaft, wherein the rim shaft and the general machine output shaft, connected in parallel, are connected with a top of a driving cone and a driven cone through a universal joint; the universal joint enables the top of the cone to swing with respect to a corresponding shaft; a transmission belt is tightly sleeved with an external surface of the driving cone and the driven cone; the adjusting rod parallel to the general machine output shaft is connected with the frame in a sliding manner; the adjusting rod has an axial moving degree of freedom; a pushing block is arranged at a free end of the adjusting rod and used for pushing a narrow side of the transmission belt; and a color coating is arranged on a surface of the transmission belt. A swinging extreme position is a position in which a busbar of the cone is parallel to an axis of a corresponding shaft, namely, the axis of the corresponding shaft is retained in a range enclosed by the cone busbar all the time; and meanwhile, the cone is capable of rotating around the axis.
Description
Technical field
The present invention relates to a kind of speed change gear that can be used for logical machine.
Background technique
Logical machine refers to the petrol engine except automobile-used and specific use, and its nominal power is generally below 30kW.It mainly as agricultural equipment for plant protection, small farm machine, graden machine, send out unit logical, the supporting power of building machinery, outboard machinery etc.Because general small-size gasoline engine volume is little, lightweight, low price, easy to use, so occupy critical positions in various machine coordinations, normally utilize logical machine force-output shaft to be connected work with other facility.Particularly among backpack machinery, general small-size gasoline engine is unique supporting power especially.Because it is widely used, also there is higher requirement in the applicability to logical machine work, specific in a certain respect, in different occasions, need to lead to machine is used in conjunction with different rotating speeds and various device, in solution thinking now, having quite a few is by belt, to carry out the transmission of power, but belt in the course of the work higher wearing and tearing be also difficult to ignore.The adjustable stepless speed change that is applied to the low wearing and tearing of logical machine force-output shaft is that technician is devoted to perfect problem always.
Summary of the invention
The invention is intended to provide a kind of Durable belt formula to lead to machine arrangements for speed regulation, to solve in prior art low wearing and tearing that logical machine force-output shaft need take into account and the problem of adjustable stepless speed change.
The logical machine arrangements for speed regulation of Durable belt formula in this programme, it is characterized in that: comprise frame, adjustable lever, drivign belt, primary shaft and logical machine force-output shaft, on the primary shaft be arrangeding in parallel and logical machine force-output shaft, by universal joint, be connected with the top that drives circular cone and driven circular cone respectively, universal joint can make the top of described circular cone shake according to corresponding axle, it is parallel with the axis of corresponding axle that the limit position of shaking is described round element of a cone, drivign belt is tightly placed in the outer surface that drives circular cone and driven circular cone, the adjustable lever that is parallel to logical machine force-output shaft is slidably connected to frame and has the degrees of freedom of moving axially, the free end of adjustable lever is provided with for promoting the pushing block on the narrow limit of drivign belt, the surface of drivign belt is provided with color coating.
It is parallel with the axis of corresponding axle that the limit position of shaking is described round element of a cone, and the axis of corresponding axle remains within described element of cone encloses the scope being, and described circular cone can rotate according to its axis simultaneously.
The feature of technique scheme is: can use logical machine to drive primary shaft rotation, drive circular cone to drive driven circular cone to rotate by drivign belt, during the moving axially of adjustable lever, pushing block promotes the narrow limit of belt moving axially along logical machine force-output shaft thereupon, belt moves axially the contact position that rear change drives circular cone and driven circular cone, realize the driving side linear velocity ratio different with slave end, to reach the stepless change of logical machine force-output shaft.In whole course of action, drive circular cone and driven circular cone constantly to keep shaking, guarantee that its minute other outer bus is parallel, belt all keeps comprehensively laminating with described circular cone, there will not be the situation of local small size contact, can not produce the concentrated situation that adds galling that waits of stress and occur.
The color coating that drivign belt surface is provided with can, for judging its degree of wear, if it is serious to fade, can tentatively judge that wearing and tearing are also heavier accordingly.
Further, logical machine force-output shaft is provided with speed probe.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the schematic diagram of the embodiment of the present invention.
Fig. 2 be in Fig. 1 A-A to schematic diagram.
