Abstract
One kind detection flywheel strength experimental rig, using pulling force machine grip holder and the flywheel clamping device connected mode of puller system；Flywheel and flywheel clamping device connected mode；Puller system applies 4900N power to flywheel along driving direction, carries out flywheel crash test.For flywheel different size, using an elongated hole is processed on flywheel clamping device, the driving Impact direction that can adjust flywheel at any time overlaps with the axis of pulling force machine grip holder.So test method accurate positioning, it is easy to operate, test speed is improved, so as to which the simultaneity that reduces labor intensity is reliable by force.
Description
Technical field
It the utility model is related to electric bicycle field.
Background technology
Electric bicycle walking-replacing tool conventional when being people's trip, because ride it is light, flexible, laborsaving and very by people's
Like.Electric bicycle must have good quality and security performance, to ensure its quality and safely and effectively using, promulgate
Relevant standard, performance requirement and detection experiment side about defining various electric bicycles and various parts in standard
Method.
Electric bicycle is according to QB/T1887-1993《People's Republic of China's light industry standard》Flywheel strength 4.4
It is required that design.Provided by standard：Less than 20 teeth flywheel along driving direction apply 4900N power, flywheel should be without breakage.
Be currently known the structure bulky of flywheel strength experimental rig, complex operation, manufacturability it is poor, in-convenience in use, and
Cost is high, and manufacture is difficult.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of detection flywheel strength experimental rig, overcomes existing
Experimental rig deficiency, while simplify the structure of fixture and processing technology, reduce cost, improve the precision of measurement.
In order to solve the above-mentioned technical problem, the scheme of the utility model use is：One kind detection flywheel strength experimental rig
It is made up of puller system, pulling force machine grip holder, flywheel clamping device, elongated hole, flywheel；One end of described pulling force machine grip holder and pulling force
Machine connects；The other end of described pulling force machine grip holder is connected with flywheel clamping device；Described flywheel connects with flywheel clamping device
Connect；Described flywheel clamping device processes an elongated hole, adjusts different size flywheel along driving direction stress.
The beneficial effects of the utility model are, due to the pulling force machine grip holder using puller system and flywheel clamping device connection side
Formula；Flywheel and flywheel clamping device connected mode；Puller system applies 4900N power to flywheel along driving direction, carries out flywheel
Crash test.For flywheel different size, using an elongated hole is processed on flywheel clamping device, the drive of flywheel can be adjusted at any time
Dynamic Impact direction overlaps with the axis of pulling force machine grip holder.So test method accurate positioning, it is easy to operate, improve test speed and
Frequency, so as to which the simultaneity that reduces labor intensity is reliable by force.
Brief description of the drawings
1. Fig. 1 is a kind of detection flywheel strength experimental rig front view.
2. Fig. 2 is a kind of detection flywheel strength experimental rig left view.
3. Fig. 3 is a kind of detection flywheel strength experimental rig flywheel clamping device top view figure.
In figure：
1. puller system, 2 pulling force machine grip holders, 3 flywheel clamping devices, 4 elongated holes, 5 flywheels
Embodiment
The utility model is described in further details with reference to the accompanying drawings and detailed description：
As seen from Figure 1, a kind of detection flywheel strength experimental rig be by puller system, pulling force machine grip holder, flywheel clamping device,
Elongated hole, flywheel composition；One end of described pulling force machine grip holder is connected with puller system；The other end of described pulling force machine grip holder is with flying
Take turns clamping device connection；Described flywheel is connected with flywheel clamping device；Described flywheel clamping device processes an elongated hole, adjusts
Whole different size flywheel is along driving direction stress.
One end of pulling force machine grip holder is fixedly connected with puller system；The other end of pulling force machine grip holder is consolidated with flywheel clamping device
Fixed connection；Flywheel is connected with flywheel clamping device；Adjustment flywheel driving Impact direction is solid after being overlapped with the axis of pulling force machine grip holder
It is fixed.
After puller system force 4900N, flywheel meets QB/T1887-1993 without breakage《People's Republic of China's light industry mark
It is accurate》The design requirement of flywheel strength 4.4.
