Abstract
The invention discloses an inner-cone universal gasoline engine speed regulating device and aims to solve the problem that stepless speed change is required to be adjusted through a gasoline engine power output shaft in the prior art. The inner-cone universal gasoline engine speed regulating device comprises a machine frame, a universal gasoline engine and the universal gasoline engine power output shaft, wherein an inclined sliding groove is formed in the machine frame; the universal gasoline engine is arranged on a sliding seat; the sliding seat is in sliding fit with the inclined sliding groove; a convex cone disk is arranged on an output shaft of the universal gasoline engine; a concave cone disk is arranged at the end part of the universal gasoline engine power output shaft; the conical surfaces of the convex cone disk and the concave cone disk contact with each other in a matching manner; the inclination of the upper edge of a common longitudinal section of the convex cone disk, the concave cone disk and the inclined sliding groove is consistent; a rack is arranged on the sliding seat; a gear shaft which is rotatably connected with the machine frame is meshed with the rack; a worm gear is arranged on the gear shaft; a worm which is rotatably connected to the machine frame is meshed with the worm gear; a driving handle is arranged on the worm. When the sliding seat slides in the inclined sliding groove, the universal gasoline engine moves accordingly, and the convex cone disk moves to change the contact position between the convex cone disk and the concave cone disk, so that different linear speed ratios of the driven side are achieved, and the stepless speed change of the universal gasoline engine power output shaft 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 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 be there is to higher requirement in the applicability of logical machine work, specific in a certain respect, in different occasions, need to lead to machine and be used in conjunction with different rotating speeds and various device.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 female cone to lead to machine arrangements for speed regulation, to solve in prior art logical machine force-output shaft, need the problem of adjustable stepless speed change.
The logical machine arrangements for speed regulation of female cone in this programme, it is characterized in that: comprise frame, logical machine and logical machine force-output shaft, frame is provided with oblique chute, logical machine is located at slide, slide is slidably matched with oblique chute, the output shaft of logical machine is provided with convex surface cone dish, logical machine force-output shaft end is provided with concave surface cone dish, convex surface cone dish contacts with the cone match of concave surface cone dish, convex surface cone dish, the inclination of the upper edge, longitudinal section that concave surface cone dish is common with oblique chute is consistent, slide is provided with tooth bar, the gear shaft and the tooth bar that are rotationally connected with frame mesh, on gear shaft, be also provided with worm gear, be rotationally connected with the worm and wheel engagement of frame, worm screw is provided with driving handle.
The feature of technique scheme is: because the inclination of the common upper edge, longitudinal section of convex surface cone dish, concave surface cone dish and oblique chute is consistent, when slide slides in oblique chute, logical machine also moves thereupon, convex surface cone dish moves the contact position having changed with concave surface cone dish simultaneously, realize the different linear velocity ratio of slave end, to reach the stepless change of logical machine force-output shaft.
Its concrete operating method is: by driving handle rotary worm, worm screw drives worm gear and gear shaft to rotate, gear shaft orders about slide straight line motion by tooth bar, latching characteristics due to worm and gear, can guarantee the stability of mechanism, in operatorless situation, convex surface cone dish and concave surface cone dish can changes.
Further, gear shaft is provided with the lock pin for locked its rotational freedom.Further improve the reliability of mechanism under steady operational status.
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.
Embodiment
Reference character in Figure of description comprises: frame 1, logical machine 2, convex surface cone dish 21, logical machine force-output shaft 3, concave surface cone dish 31, oblique chute 4, slide 5, tooth bar 51, gear shaft 6, worm screw 7, driving handle 71.
Substantially as shown in Figure 1: in the present embodiment, comprise frame, logical machine and logical machine force-output shaft, frame is provided with oblique chute, logical machine is installed on slide, slide is slidably matched with oblique chute, and the output shaft of logical machine is provided with convex surface cone dish, and logical machine force-output shaft end is provided with concave surface cone dish, convex surface cone dish contacts with the cone match of concave surface cone dish, and the inclination of the upper edge, longitudinal section that convex surface cone dish, concave surface cone dish and oblique chute are common is 45 °.Slide is provided with tooth bar, gear shaft and tooth bar engagement with frame is rotationally connected, be also provided with worm gear (not shown) on gear shaft, be rotationally connected with the worm and wheel engagement of frame, worm screw is provided with driving handle, and gear shaft is provided with the lock pin for locked its rotational freedom.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic is not done unnecessary description at this, and part-structure also do not 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, not departing under the prerequisite of structure of the present invention, can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
