Abstract
The invention discloses a belt type general machine speed changing device and aims at solving the problems in the prior art. The belt type general machine speed changing device comprises a frame, an adjusting rod, a belt, a rim shaft and a general machine output shaft, wherein a driving cone and a driven cone are arranged on the rim shaft and the general machine output shaft which are arranged in parallel; adjoined side lines in a common longitudinal section between the driving cone and the driven cone are parallel; the belt is tightly sleeved with 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 belt; and a roller, arranged on the adjusting rod and contacted to a wide side of the belt, is used for tightening the belt. The belt type general machine speed changing device is characterized in that: the general machine drives the rim shaft to rotate; the driving cone drives the driven cone to rotate through a transmission belt; when the adjusting rod moves axially, the pushing block push the narrow side of the belt to move along with the adjusting rod; and after the belt moves, a contact part between the driving cone and the driven cone is changed, so that stepless speed change of the general machine output shaft is achieved.
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 belt type to lead to machine speed change gear, to solve in prior art logical machine force-output shaft, need the problem of adjustable stepless speed change.
The logical machine speed change gear of belt type in this programme, it is characterized in that: comprise frame, adjustable lever, belt, primary shaft and logical machine force-output shaft, on the primary shaft be arrangeding in parallel and logical machine force-output shaft, be respectively equipped with and drive circular cone and driven circular cone, drive circular cone parallel with sideline adjacent in the common longitudinal section of driven circular cone, belt is tightly placed in and drives on 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 belt, adjustable lever is provided with the roller that contacts with belt broadside for tightening belt.
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.
Further, plural pushing block is C shape the narrow limit that is folded in belt both sides, the position of the steady change belt that can more coordinate.
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 the embodiment of the present invention Fig. 1 pushing block and belt part A-A to schematic diagram.
Embodiment
Reference character in Figure of description comprises: primary shaft 1, logical machine force-output shaft 2, driving circular cone 3, driven circular cone 4, belt 5, adjustable lever 6, pushing block 61, roller 62.
Substantially as depicted in figs. 1 and 2: in the present embodiment, comprise frame, adjustable lever, belt, primary shaft and logical machine force-output shaft, on parallel and horizontally disposed primary shaft and logical machine force-output shaft, be respectively equipped with and drive circular cone and driven circular cone, drive circular cone parallel with sideline adjacent in the common longitudinal section of driven circular cone, belt is tightly placed on the conical surface that drives circular cone and driven circular cone, the adjustable lever that is parallel to logical machine force-output shaft arranges by the bearing horizontal slip in frame, the free end of adjustable lever left is provided with for promoting the pushing block on the narrow limit of belt, two each and every one pushing blocks are C shape the narrow limit that is folded in belt both sides, adjustable lever is provided with the roller that contacts with belt broadside for tightening belt.
Because belt is an annular, so can see two belts in Fig. 2, certainly also just there is corresponding with it pushing block, the stability of adjusting in order to improve belt position can also be set up more pushing block in different level heights.
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.
Claims (2)
1. belt type leads to machine speed change gear, it is characterized in that: comprise frame, adjustable lever, belt, primary shaft and logical machine force-output shaft, on the primary shaft be arrangeding in parallel and logical machine force-output shaft, be respectively equipped with and drive circular cone and driven circular cone, drive circular cone parallel with sideline adjacent in the common longitudinal section of driven circular cone, belt is tightly placed in and drives on 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 belt, adjustable lever is provided with the roller that contacts with belt broadside for tightening belt.
