Description
Technical field
The invention belongs to brake component field and in particular to a kind of plastic shaping bias band brake.
Background technology
Brake is that have to make moving component（Or movable machinery）Deceleration, stopping or the dress keeping the functions such as halted state
Put, be commonly called as brake, lock.Brake is mainly made up of frame processed, brake component and manipulation device etc..Some brakes are also equipped with brake component
The automatic regulating apparatus in gap.Brake can be divided into outer according to version：Embrace block brake, interior shoe brake, band
Formula brake, disk brake etc..
Band brake, braking member be an external beam in the banded structure thing of brake drum, become brake band, in order to ensure
Separation between the intensity of braking and contact brake band and drum, brake band is typically made using stalloy, and riveting thereon
It is connected to friction facing, to increase its frictional force and wearability.However, change material and the characteristic of brake band anyway, but,
Brake band is when contacting the brake head of braking member and runs up, therefore, in the running of high speed, two element phases
Mutual friction, larger frictional force will certainly be produced it can be seen that, the loss of friction belt is serious, after the time is longer, causes braking effect
Fruit weakens, then need the brake band more renewing, and increases cost.
Content of the invention
The technical problem to be solved in the present invention is big, braking effect difference and high cost to be lost for existing band brake
Shortcoming, a kind of plastic shaping bias band brake that little, good braking effect and low cost are lost is provided.
In order to solve above-mentioned technical problem, the present invention provides following technical scheme：Plastic shaping bias band brake, bag
Including rack, driving wheel, braked wheel, eccentric dynamic wheel and brake unit, braked wheel is located at end face, braked wheel and the driving of driving wheel
It is provided with slide bar, braked wheel is connected with sliding bar, the main core of braked wheel is located at same axle center with the axle center of driving wheel between wheel；
In frame and an axle center of eccentric dynamic wheel is connected eccentric dynamic wheel with gantry rotation, and brake unit includes rod-type braking
Device and wheeled type braking, rod-type brake unit includes brake bar, brake head and tripping spring, and one end of brake bar connects system
Dynamic head, the other end of brake bar is offseted with eccentric dynamic wheel, and brake head is cylindrical near driving wheel, and tripping spring is sheathed on braking
Outside bar；Wheeled type braking is included located at the first gear near driving wheel side for the braked wheel and second gear, first gear
It is provided with first rotating shaft and braked wheel between, between first gear and second gear, is provided with the second rotating shaft, second gear is near driving
One side end of wheel is provided between braking brake pad and second gear end face and driving wheel and is provided with back-moving spring, and braked wheel is near drive
The side of driving wheel is provided with the tooth bar engaging with first gear and second gear.
Using the plastic shaping bias band brake of technical solution of the present invention, braked wheel can give the system of driving wheel end face
Power, eccentric dynamic wheel gives the brake force that driving wheel is braked from side.On the one hand, eccentric dynamic wheel rotates in frame, with
The rotation of eccentric dynamic wheel, brake force can be transmitted to brake bar near driving wheel side by the end of the brake bar offseting with it
Brake head one end, thus compression spring makes the side of brake head and driving wheel offset generation friction, thus braking；The opposing party
Face, when braking, give braked wheel to driving wheel to thrust so that braked wheel runs to driving wheel side so that the
The brake pad of two geared end is offseted with the end of driving wheel, thus producing frictional force, during braking, due to brake pad
Moment driving wheel can not possibly be braked, when brake pad touches the end of driving wheel, due to the inertia of high speed, brake pad can be with
Driving wheel together to rotate, thus by power anti-pass pass with second gear, the second rotating shaft, first gear, first rotating shaft, transmission with
Braked wheel, and braked wheel, more reversely by brake force transmission and brake pad, transmits back and forth, so that brake pad and driving wheel end
Between frictional force driving wheel braked stop, meanwhile, only understand simultaneously, with first gear, second eat the tired tooth bar engaging
The effect of braking equally can be increased.Because, during only understanding, wheel brake plays main braking action, and belt braking
Device helps out, and the in addition friction of wheel brake relies on the transmission of strength each other, in conjunction with band brake from driving
The side of wheel is braked, thus slowing down the frictional dissipation that braking causes, after life-time service, can reduce replacing brake head, friction
The number of times of block, good braking effect and can increasing the service life.
Further, the side attachment of described driving wheel has friction belt, and the head of described brake head is provided with friction head.Rub
Wipe band and can strengthen frictional property, thus braking effect is more preferable with friction head cooperation.
Further, described driving wheel is provided with groove near one end end face of second gear, is provided with friction plate in groove, institute
Friction plate is also attached with the braking brake pad stated.Brake pad be can be inserted in groove brake, it is to avoid sliding, same road
Reason, is coordinated with brake pad in the friction plate driving wheel end, braking effect is more preferable.
Further, described friction head is memory metal friction head, the described friction plate of second gear end and braking
Friction plate on brake pad is memory metal friction plate.Memory metal is also referred to as memorial alloy, using some alloys in solid-state
When the rule that changes with temperature of its crystal structure, for example, Ni-Ti alloy is more than 40 DEG C and less than 40 DEG C of crystal structure
Different, but when temperature changes about 40 DEG C, alloy will contraction or expansion so that its form generation change.Therefore,
By memory metal be coated on metal friction head surface so that material friction deformation after, you can recover to original shape, thus
Reduce the number of times changing friction head or friction plate.
Further, described friction belt outer layer is attached with memory metal frictional layer.Same reason, also can be attached outside friction belt
Memory metal frictional layer, thus reducing the replacing number of times of friction belt.
Further, the end positioned at brake bar of described tripping spring is provided with the adjusting nut offseting with spring.Adjust
Section nut can be used for adjusting the pulling force of tripping spring, thus changing the dynamics of braking, strong applicability.
