Abstract
The invention discloses a smooth speed change device for a general purpose engine so as to solve the problem that in the prior art, a force output shaft of the general purpose engine needs adjustable stepless speed change. The smooth speed change device comprises a machine frame, a general purpose engine and a force output shaft of the general purpose engine, wherein a straight sliding chute is formed in the machine frame; the general purpose engine is in slide connection to the sliding chute through a sliding table; the straight sliding chute is perpendicular to an output shaft of the general purpose engine; two driving round plates which are symmetrically arranged are in axial slide connection to a driving shaft of the general purpose engine, a pressure spring is arranged between opposite surfaces of the two driving round plates, and two symmetric surfaces, which are away from each other, of the two driving round plates are inwards-concave smooth conical surfaces; two driven round plates are in symmetrical threaded connection to the force output shaft of the general purpose engine, locking nuts are arranged on two side surfaces of the two driven round plates, opposite surfaces of the two driven round plates are outwards-protruded smooth conical surfaces, and the driving round plates are positioned between the two driven round plates and are abutted against the two driven round plates. Through the adoption of the structure, the general purpose engine moves along the straight sliding chute, so that the contact positions of the driving round plates and the driven round plates can be changed, and the stepless speed change of the force output shaft of the general purpose engine is realized.
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 at 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 coordination, normally utilize logical machine force-output shaft to be connected work with other facility.Particularly among backpack machinery, the supporting power that general small-size gasoline engine is unique especially.Because it is widely used, higher requirement is also existed to the applicability of logical machine work, specific in a certain respect, different occasions need logical machine with different rotating speeds and various device with the use of.The adjustable stepless speed change 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 logical level and smooth speed change gear of machine, need the problem of adjustable stepless speed change to solve logical machine force-output shaft in prior art.
The level and smooth speed change gear of logical machine in this programme, it is characterized in that: comprise frame, logical machine and logical machine force-output shaft, frame is provided with straight runner, logical machine is slidably connected on chute by slide unit, straight runner is vertical with logical machine output shaft, the live axle of logical machine symmetrically arranged two driver plates have been in axial sliding connection, stage clip is provided with between the face that two driver plates are relative, two driver plates from two symmetry plane be the round and smooth conical surface of indent, on logical machine force-output shaft, symmetry is threaded two driven disks, the both sides of two driven disks are all respectively provided with locking nut, the face that two driven disks are relative is the round and smooth conical surface of evagination, driver plate is between two driven disks and offset.
By said structure, can be moved along straight runner by logical machine, thus change the contact position of driver plate and driven disk, to reach the stepless change of logical machine force-output shaft.
Further, the circular arc curvature of driver plate is greater than driven disk.This feature can improve the accuracy of equipment operation, when avoiding it too contiguous, abnormal interference and collision occurs.
Accompanying drawing explanation
Figure l is the schematic top plan view of the embodiment of the present invention.
In accompanying drawing: l, logical machine, 2, straight runner, 3, output shaft, 4, driver plate, 4l, stage clip, 5, driven disk, 6, logical machine force-output shaft.
Embodiment
As shown in Figure l: comprise logical machine force-output shaft in the present embodiment, frame is provided with straight runner, logical machine is slidably connected on chute can be radially slided by slide unit, straight runner leads to the live axle of machine output shaft perpendicular to logical machine, axle slidably connects symmetrically arranged two driver plates, driver plate can slide axially but not rotatable, stage clip is connected with between two driver plate opposing sides, two driver plates from two symmetry plane be the round and smooth conical surface of indent, on logical machine force-output shaft axle, symmetry is threaded two driven disks, the both sides of two driven disks are all respectively provided with locking nut, can be used for the position regulating driven disk.The face that two driven disks are relative is the round and smooth conical surface of evagination, and driver plate is between two driven disks and offset.The circular arc curvature of driver plate is greater than driven disk.Output shaft is provided with the range sensor for detecting driver plate position.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do unnecessary description at this, and part-structure does not also illustrate in the drawings, but does not affect person of ordinary skill in the field to the understanding of this technological scheme and realization.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
