Description
Technical field
The utility model belongs to speed increaser field, and in particular to a kind of lever speed increaser.It can apply in aviation, automobile
The fields such as steamer.
Background technique
Speed increaser, which refers to, is mounted on independent type closed driving device between prime mover and working machine, for increasing revolving speed.It passes
Dynamic device is the chief component of most of machines.Driving member and transmission designs whether rationally, manufacture and assembling quality
Whether meet the requirements, the key for determining product quality will be become.Transmission can be divided into machine driving, Fluid-transmission and electric transmission three
Class.And machine driving is divided into engaged transmission and frictional drive by its working principle, is specifically divided into chain conveyer, V belt translation, gear and passes
Dynamic, four class of worm-drive.Gear drive is most important, most widely used a kind of driving form in machine driving.
Utility model content
The purpose of this utility model is to provide a kind of lever speed increaser.The utility model not only speedup but also laborsaving, structure letter
It is single, practical, be convenient for mass production, carry out speedup using lever principle band moving gear, can be superimposed and be used with multiple groups, when operation
Not only speed had been improved but also laborsaving.
The technical solution adopted is that:
A kind of lever speed increaser, including fixed plate, lever mechanism and gear mechanism, it is characterised in that:
Lever mechanism, including hammer rotor, first connecting rod, L-type lever, second connecting rod, the first pin shaft and the second pin shaft.The
One pin shaft is installed in the correspondence axis hole of fixed plate and loose fit, and the centre bore of hammer rotor is installed on the first pin shaft and consolidates
Fixed connection, the small head end of hammer rotor and one end of first connecting rod are hinged, the other end of first connecting rod and the length of L-type lever
Support arm end is hinged, and the second pin shaft is installed on the correspondence axis hole of fixed plate and is fixedly connected, and is equipped with axis in the inflection point of L-type lever
Hole, the inflection point upper shaft hole of L-type lever is installed on the second pin shaft and loose fit, one end of second connecting rod and L-type lever it is short
Support arm end is hinged.
Gear mechanism, including first gear, second gear and third gear.The other end of second connecting rod and first gear
End face is hinged by pin shaft.The wheel shaft of first gear is installed in the correspondence axis hole in fixed plate Nei and loose fit, first gear
Be greater than the diameter of second gear with the diameter of third gear, the wheel shaft of second gear be installed in the correspondence axis hole in fixed plate Nei and
Loose fit, second gear and third gear are in-line gears, first gear and second gear engagement.
Rotary hammer type rotor, first connecting rod, L-type lever, second connecting rod, first gear, second gear and third gear according to
Secondary rotation carries out speedup, as one group.In use, can be connected with multiple groups, by the third gear of previous group and the hammer of later group
Formula rotor is connected by gear, and so on, reach enough speed.
Working principle is that the external strength given of hammer rotor reception drives its rotation, such as hand shaken, motor
Or bavin, gasoline engine drive.Hammer rotor is rotated by the center of circle of the first pin shaft, and hammer rotor one end and first connecting rod are hinged, is driven
First connecting rod movement, first connecting rod and L-type lever are hinged, and L-type lever is rotated by the center of circle of the second pin shaft, second connecting rod and L-type
Lever is hinged, and L-type lever drives second connecting rod movement, and second connecting rod drives first gear rotation, first gear and second gear
Engagement, second gear and third gear are in-line gears, and first gear drives second gear and third gear to rotate simultaneously.This reality
With new application lever principle, apply lesser power on hammer rotor, the transmitting by L-type lever to power makes first gear
Transmit out biggish power.By the engagement of first gear and second gear, first gear drives second gear rotation, due to first
The diameter of gear is greater than second gear, so when first gear and second gear turn over the identical number of teeth, second gear rotation
All numbers are greater than all numbers of first gear rotation.Second gear and third gear are in-line gears, and second gear and third gear turn
Dynamic all numbers are identical, and the diameter of third gear is greater than the diameter of second gear, and the outside transmission speed of third gear is completed to increase
Speed.It is used in use, can be superimposed with multiple groups.The first pin shaft on third gear and second group of speed increaser on first group of speed increaser
It is connected by gear.
The advantage is that: the utility model structure it is simple, it is practical, be convenient for mass production, driven using lever principle
Gear carries out speedup, can be superimposed and be used with multiple groups, when operation saves both time and effort.
