Abstract

The utility model discloses a starter for an unmanned helicopter. The starter comprises a starting motor, a starting motor connecting gear, a starting motor gear plate, a handle connecting column, a starter driven gear, a starting motor driven gear seat, a gear-fixed middle seat, an output fixed gear seat, a power output sleeve, a power output shaft, a starting switch, a handle and a gear power output shaft; the major part of the power output shaft is centered and arranged in the power output sleeve by a plurality of bearings; a plurality of one-way bearings are arranged between the upper bearing and the lower bearing to ensure that the power output shaft can only be rotated in one direction; the position at 1-2 cm of the top end of the power output shaft is machined into a cubic column; and the power output shaft is connected with a speed-increasing gear and a speed-reducing gear by the starting motor output shaft to increase output torque. The starter for the unmanned helicopter, disclosed by the utility model, is small and convenient to carry and is convenient for a user to start the unmanned helicopter by holding the starter through the handle.

Description

A kind of starter that is used for depopulated helicopter

Technical field

The utility model relates to technical field of engines, is specifically related to a kind of starter that is used for depopulated helicopter.

Background technique

Because the engine power of depopulated helicopter is big, rotating speed is fast, and the starter outputting torsion of general model plane is too little, can't ato unit.And the big back of engine speed, also can't re-use because of the impact force behind the engine start causes starter even started motor also bigger, the general model plane starter of impact force of the pto of starter.

The model utility content

To above-mentioned existing technology, the technical problem that the utility model will solve is: starter is the key technology that starts helicopter, and general model plane starter can't start depopulated helicopter, want starter can start depopulated helicopter at present, and starter can use repeatedly again.

In order to solve the problems of the technologies described above, the utility model adopts following technological scheme:

A kind of starter that is used for depopulated helicopter; Comprise that starting electrical machinery, starting electrical machinery connect tooth, short fixed plate supporting post, starting electrical machinery gear plate, handle link post, starter driven tooth, the driven toothholder of starting electrical machinery, the fixing middle seat of gear, output fixing tooth wheel seat, power output cover, pto, enable switch, handle, gear transmission output shaft; It is characterized in that; Said pto is most of to place power output cover with several bearing centering; Several unilateral bearings are set between metal (upper guarantee that pto can only rotate to a direction, pto top 1-2cm is processed into cube rod; Pto connects overdrive gear through the starting electrical machinery output shaft and deceleration gear increases its outputting torsion.

Said starting electrical machinery, gear transmission output shaft, power output cover and pto link the post position of center line at handle, and are in coaxial inner conductor.

Said starting electrical machinery output power is at least 12V-80A.

Said enable switch places on the handle.

Said enable switch is relay switch or air-break switch.

Compared with prior art, the utlity model has following beneficial effect:

The utility model is small and exquisite, easy to carry, and the user utilizes handle to hold starter to start depopulated helicopter very easily.

Embodiment

To combine accompanying drawing and embodiment that the utility model is done further to describe below.

Embodiment

A kind of starter that is used for depopulated helicopter; Comprise starting electrical machinery (1), starting electrical machinery connect tooth (2), short fixed plate supporting post (3), starting electrical machinery gear plate (4), handle link post (5), starter driven tooth (6), the driven toothholder of starting electrical machinery (7), gear fixing in seat (8), long fixed plate supporting post (9), output gear wheel seat (10), secondary output gear shaft (11), output fixed gear wheel seat strut (12), output fixing tooth wheel seat (13), power output overlap (14), pto (15), enable switch (16), handle (17) and gear transmission output shaft (18); It is characterized in that; Said pto is most of to place power output cover with several bearing centering; Several unilateral bearings (20) are set between metal (upper (19) guarantee that pto can only rotate to a direction, pto top 1-2cm is processed into cube rod; Pto connects overdrive gear through the starting electrical machinery output shaft and deceleration gear increases its outputting torsion.

Starting electrical machinery (1) and starting electrical machinery gear plate are fixedly mounted on handle link post central position; One handle is respectively installed in handle link post both sides; Short fixed plate supporting post (3) is installed between starting electrical machinery gear plate (4) and the fixing middle seat of gear (8), and starting electrical machinery connects tooth (2) and is connected on the starting electrical machinery output shaft, and is installed in short fixed plate supporting post (3) below; Starting electrical machinery driven tooth and secondary output gear link together through the secondary output gear shaft; Welding one long fixing branch dagger between output fixing tooth wheel seat and starting electrical machinery gear plate; Between seat (8) output gear wheel seat (10) is set during output fixing tooth wheel seat (13) and gear are fixing, output gear and fixing with power output cover is set on the output gear wheel seat.

When opening enable switch; Motor rotates and drives starting electrical machinery connection tooth (2) rotation, and starting electrical machinery connection tooth drives starting electrical machinery driven tooth (6) and rotates, while secondary output gear rotation; The output gear that the secondary output gear drives on the output gear wheel seat (10) rotates; Further drive output cover rotates, and power is exported pto (15) is rotated, and pto drives the engine start axle and rotates.Behind engine start, the rotating speed of engine start axle is during greater than the rotating speed of pto (15), and the engine start axle drives pto and rotates at faster speed, this moment parallel taking-up starter.
