Abstract
The utility model relates to a primary transmission mechanism for a single ultra-light helicopter. The primary transmission mechanism is a horizontal transmission and speed reducing mechanism, and comprises a big synchronous pulley, a small synchronous pulley, a cover plate bearing seat and a coupler; the small synchronous pulley is arranged on an output shaft of an engine; an M-shaped synchronous pulley, which is taken as a power transmission part, is arranged between the small synchronous pulley and the big synchronous pulley; and the coupler is arranged above the big synchronous pulley. The primary transmission mechanism is simple in structure, low in manufacturing cost, simple and easy in processing and rapid in popularization, especially runs horizontally, is stable and low in noise, and is easy to maintain and facilitates part replacement as being in an exposed way.
Description
Technical field
The utility model relates to a kind of single microlight-type helicopter one-level transmission device.
Background technology
In existing technology, after more traditional one-level transmission device often directly slowed down with osed top basin angle gear case, transferring power was to the rotor of helicopter again.The drop-gear box casing needs the die casting of die sinking tool, and the gear process in the casing requires also very high, and profile and inner structure are all complicated.Because of the small batch production cost is too high, need produce by major company of big factory, can not popularize with popular.
Technology contents
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of single microlight-type helicopter one-level transmission device simple in structure is provided.
The technical solution adopted in the utility model is:
The single microlight-type helicopter of the utility model is a horizontally-mounted transmission speed reducer structure with the one-level transmission device, comprises big synchronous pulley, small synchronous pulley, plate shaft bearing and coupler.Small synchronous pulley is installed on the engine output shaft, has adopted M type synchronous pulley as the transmission of power parts between small synchronous pulley and big synchronous pulley.Coupler is equipped with in big synchronous pulley top.
The utility model is simple in structure, cheap, processing is simple and easy, and penetration and promotion is fast; Especially with horizontal type level operation, stable, low noise and adopt bareing overhauls change part easily.
Description of drawings
Fig. 1 is the utility model one-level transmission device front schematic view
Fig. 2 is an one-level transmission device schematic top plan view.
Among the figure: 1 synchronizer gear band, 2 big synchronous pulleys, 3 small synchronous pulleys, 4 bolt of rear end plates, 5 plate shaft bearings, 6 pipe links, 7 bearer bar side plates, 8 driving engines, 9 coupler.
The specific embodiment
Referring to Fig. 1, Fig. 2, the utility model mainly combines novel one-level transmission speed reducer structure by synchronizer gear band 1, big synchronous pulley 2, small synchronous pulley 3, bolt of rear end plate 4, plate shaft bearing 5, pipe link 6, bearer bar side plate 7 and coupler 9.Driving engine 8 makes power pass through one-level transmission speed reducer structure accurate transfer by the Throttle Opening Control rotating speed.The single microlight-type helicopter of the utility model is a horizontally-mounted transmission speed reducer structure with the one-level transmission device.Its small synchronous pulley 3 is installed on driving engine 8 output shafts, has adopted M type synchronous pulley 1 as the transmission of power parts between small synchronous pulley 3 and big synchronous pulley 2, and small synchronous pulley 3 passes to big synchronous pulley 2 by M type synchronizer gear band 1 with power.Big synchronous pulley 2 tops are provided with plate shaft bearing 5, and sidepiece is provided with bearer bar side plate 7; Big synchronous pulley 2 is installed in plate shaft bearing 5 times and the bearer bar side plate 7, forms the body structure of semi-surrounding.Above-mentioned material is all used aviation aluminium turning manufacturing.The body structure of semi-surrounding is connected and fixed with bolt of rear end plate 4.Coupler 9 is equipped with in big synchronous pulley 2 tops, and coupler 9 is connected with the pipe link 6 of its top, and the effect of pipe link 6 is that the power of big synchronous pulley 2 by coupler 9 outputs is upwards transmitted, and it also is with aviation aluminium turning manufacturing.The body structure of semi-surrounding is connected and fixed small synchronous pulley 3 with bolt 4.Big synchronous pulley 2 is 1: 2.5 with the transmitting ratio of small synchronous pulley 3.
