Description

Economize power drive

The utility model belongs to a kind of driving mechanism, particularly relates to a kind of drive unit with laborsaving function.

In simple and mechanical field, the laborsaving function of pulley is as far back as just being found by people a long time ago, and be used in produce and life in.It has brought many convenience to people, is used on the crane, on the first-class machinery of elevator the time, can mentions heavier object with less power as pulley.Even so, but in the machinery of other industry, more do not used, to bring into play its bigger purposes, this mainly is because pulley constitutes sheave block as a kind of driving mechanism, exist structural unreasonablely, labour-saving characteristics more can not mated existing member well, make it not obtain better application, this point then is that people are for a long time to a blind spot on the sheave block understanding.

At problem set forth above, the utility model provides a kind of province power drive, and its purpose is to solve structurally unreasonable of traditional driving mechanism, makes it more laborsaving.

The utility model is achieved through the following technical solutions:

A kind of province power drive is characterized in that: this driver mainly is made of three parts, and first portion mainly constitutes by importing motive power wheel, large crankshaft and big crank into for importing the power crankshaft device into, and three members are fixed together; Second portion is laborsaving box body device, mainly is made of three groups of pulleys; Third part is the outputting power crankshaft arrangement, mainly is made of outputting power wheel, small crankshaft and small crank, and three members are fixed together; These three parts all are fixed on the support, and crank, pulley connect by stone dead wire.

Large and small crank is made of three curved bars, and the angle of each curved bar is 120 °.

The laborsaving box body device of second portion is made up of two groups of static pulley and one group of movable pulley, and every group of pulley all is made up of three pulleys; Running block is arranged in the housing, and the bottom of housing is provided with track; Steel wire is walked around running block and another static pulley group by the static pulley group, is fixed on the housing; The other end of housing is connected on the small crank of outputting power crankshaft arrangement by steel wire.

Advantage of the present utility model and effect:

Great advantage of the present utility model is to exist on the structure more rationally, and more the labour-saving characteristics can be mated well with existing member, make it obtain wider application area.

If apply in the following mechanical device economizing power drive, these mechanical device raising work are renderd a service, to reach energy-conservation effect.

1, electrocar, battery-operated motor cycle, solar car can improve the speed of a motor vehicle under the effect that economizes power drive or increase power makes car increase carrying capacity.

2, wind-power electricity generation, tidal power generation, under the situation of not economizing power drive, wind-force or morning and evening tides do not reach a certain amount of, just can not generate electricity, and economize the power that power drive can improve generator and use, thereby improve generated energy.

3, bicycle, pedicab, residual nationality people handcar can improve the speed of a motor vehicle or increase carrying capacity under province's power drive effect.

Except that above application area, can also use in other running machinery, to reach laborsaving speedup and to improve the effect that power increases carrying capacity.

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is the plan view of accompanying drawing 1;

Accompanying drawing 3 is user mode figure of the present utility model.

The utility model is specifically described by mode of execution below in conjunction with accompanying drawing:

Structure of the present utility model mainly is divided into three parts, and first portion is importing the power crankshaft device into, and second portion is laborsaving box body device, and third part is the outputting power crankshaft arrangement.Their three parts are connected on the fixed support 16 jointly.

First portion is a bent axle 1 that has three longer cranks 4, and the two ends of bent axle 1 respectively are with a bearing 2, and is connected on the fixed support 16, and a wherein end of bent axle 1 prolongs and fixed support 16 parts, and adds that imports a motive power wheel 3 into.The angle that is connected between three curved bars of long crank 4 on the bent axle 1 equates that be 120 °, each long crank 4 top all is connected with an axostylus axostyle, the fixing clamp 5 that shaft rod upper sleeve has tape spool to hold.The other end of fixing clamp 5 can be clamped stone dead wire 6.

Second portion is made up of a sheave block casing, and three sheave block arranged side by side are arranged in the casing 12, and each sheave block is made up of three pulleys.The pulley 7 of holder stone dead wire is a static pulley, they are enclosed within on the axis 17 together, the two ends of axis 17 are connected on the shell 12 of pulley casing, and other one group of static pulley 8 also is enclosed within on the axis 17 together, and the two ends of axis 17 are connected on the shell 12 of pulley casing.Also having one group of pulley is running block 9, a fixing shell 11 all is housed on each movable pulley, the track 10 that can supply the movable pulley shell to be free to slide respectively is equipped with at the two ends up and down of shell 11, track 10 is connected on the shell 12 of sheave block casing, respectively there is a fixedly folder hole of stone dead wire the rear and front end of movable pulley shell 11, and movable pulley shell 11 is installed in the track 10.

Third part is a bent axle 14 that has small crank, and the two ends of bent axle 14 respectively are with a bearing, and is connected on the fixed support 16, and a wherein end of bent axle 14 prolongs and fixed support 16 parts, and adds an outputting power wheel 15.The angle that is connected between three curved bars of small crank 13 on the bent axle 14 equates, all is 120 °.All there is individual axostylus axostyle on the top of each small crank 13, the fixing clamp 5 that shaft rod upper sleeve has tape spool to hold, and the other end of fixing clamp 5 can be clamped stone dead wire 6.

These three parts all are fixed on the support 16, by stone dead wire 6 this three part are coupled together at last.Its connecting means is to be clamped separately in the sheave block casing that a stone dead wire 6 is connected into second portion by the fixing clamp 5 on three long cranks 4 in the first portion, earlier by holding in the palm the static pulley 7 of stone dead wire, respectively stone dead wire 6 on corresponding three movable pulleys 9 with it, and then, again stone dead wire 6 is fixed on the fixing clamp of movable pulley 9 shells 11 front ends at last around to three other static pulley 8.Connect three stone dead wires 6 equally in the folder hole of shell 11 rear ends of three movable pulleys 9, every stone dead wire 6 is connected in respectively on the fixing clamp of corresponding with it small crank 13 upper ends in the third part.So just finished the constructional device of economizing power drive.Its working procedure is: when power by importing motive power wheel 3 into, after power being imported into the bent axle 1 of first portion, bent axle 1 drives three long cranks 4 and rotates, and long crank 4 stressed tension stone dead wires 6 have just driven the movable pulley 9 in the second portion also along with moving after stone dead wire 6 is pulled.When movable pulley 9 moves,, make small crank 13 drive bent axle 14 runnings, and power is transferred out power by outputting power wheel 15 again 13 pullings of the small crank in the third part that connects.So the bent axle 1 of first portion continuously turns round, make three movable pulleys 9 in the second portion be spurred by stone dead wire 6 and ceaselessly move, the laborsaving function of sheave block is filled part play a role, then the small crankshaft 14 by driving third part is gone out the power that increase to power transmission by outputting power wheel 15 again.

Accompanying drawing 3 is the utility model application on bicycle.The sheave block casing is fixed on the cant beam, and the motive power wheel 3 that imports on the large crankshaft 1 connects with pedal wheel, and the outputting power wheel 15 on the small crankshaft 14 connects with the flywheel in the trailing wheel, thereby makes more laborsaving by bike.
