Description
Technical field
The invention belongs to brake component field, be specifically related to the eccentric band brake of a kind of plastic shaping.
Background technique
Break has the device making moving element (or movable machinery) deceleration, stop or keeping the functions such as halted state, is commonly called as brake, lock.Break is primarily of compositions such as frame processed, brake component and Effectors.Some break is also equipped with the automatic regulating apparatus in brake component gap.Outside break can be divided into according to structural type: embrace block brake, interior shoe brake, band brake, disk type braker etc.
Band brake, braking member is that an external beam is in the banded structure thing of brake drum, become clamping strap, in order to ensure the intensity of braking and the Separation contacted between clamping strap and drum, clamping strap generally adopts stalloy to make, and riveted joint has friction facing, to increase its frictional force and wear resistance thereon.But, in any case change material and the characteristic of clamping strap, but, clamping strap is when contacting the brake head of braking member and runs up, therefore, in running at a high speed, the mutual friction of two element phases, will certainly produce larger frictional force, as can be seen here, the loss of friction belt is serious, after time is longer, cause braking effect to weaken, then need the clamping strap more renewed, increase cost.
Summary of the invention
The technical problem to be solved in the present invention be large for existing band brake loss, braking effect is poor and the shortcoming that cost is high, provides that a kind of loss is little, good braking effect and the low eccentric band brake of plastic shaping of cost.
In order to solve the problems of the technologies described above, the invention provides following technological scheme: the eccentric band brake of plastic shaping, comprise frame, driving wheel, Brake drum, eccentric dynamic wheel and braking device, Brake drum is positioned at the end face of driving wheel, slide bar is provided with between Brake drum and driving wheel, Brake drum is connected with sliding bar, and the main core of Brake drum and the axle center of driving wheel are positioned at same axle center; Eccentric dynamic wheel is located in a frame and eccentric axle center and is connected with gantry rotation, braking device comprises rod-type braking device and wheeled type braking, rod-type braking device comprises brake rod, brake head and brake spring, one end of brake rod connects brake head, the other end of brake rod and eccentric dynamic are taken turns and are offseted, brake head is near the cylindrical of driving wheel, and brake spring is sheathed on brake rod outside; Wheeled type braking comprises is located at first gear of Brake drum near driving wheel side and the second gear, the first rotating shaft is provided with between first gear and Brake drum, the second rotating shaft is provided with between first gear and the second gear, second gear is provided with braking brake pad near a side end of driving wheel and is provided with Returnning spring between the second gear face and driving wheel, and Brake drum is provided with the tooth bar with the first gear and the second gears meshing near the side of driving wheel.
Adopt the eccentric band brake of the plastic shaping of technical solution of the present invention, Brake drum can give the braking force of driving wheel end face, and eccentric dynamic wheel gives the braking force that driving wheel is braked from the side.On the one hand, eccentric dynamic wheel rotates in frame, along with the rotation of eccentric dynamic wheel, braking force can be transmitted to brake rod brake head one end near driving wheel side by the end of the brake rod offseted with it, thus Compress Spring makes the side of brake head and driving wheel offset produces and rub, thus braking, on the other hand, when braking, give Brake drum to driving wheel to thrust, Brake drum is run to driving wheel side, thus the brake pad of the second geared end and the end of driving wheel are offseted, thus generation frictional force, in the process of braking, because driving wheel can not be braked by brake pad instantaneously, when brake pad touches the end of driving wheel, due to inertia at a high speed, brake pad together can rotate along with driving wheel, thus power anti-pass is passed and the second gear, second rotating shaft, first gear, first rotating shaft, at transmission and Brake drum, and Brake drum is reverse by braking force transmission and brake pad again, transmit back and forth, thus driving wheel is braked by the frictional force between brake pad and driving wheel end stop, simultaneously, only understanding simultaneously, with the first gear, second tooth bar eating tired engagement can increase the effect of braking equally.Owing to only understanding in process, wheel brake plays main braking action, and band brake helps out, the friction of wheel brake relies on the transmission of strength each other in addition, brake in conjunction with the side of band brake from driving wheel, thus slow down the frictional loss of braking and causing, after Long-Time Service, the number of times changing brake head, brake pad can be reduced, 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.Friction belt coordinates with friction head can strengthen frictional property, thus braking effect is better.
Further, described driving wheel is provided with groove near one end end face of the second gear, is provided with friction plate in groove, and described braking brake pad is also attached with friction plate.Brake pad can be inserted in groove brake, avoid slippage, same reason, coordinate with brake pad at the friction plate of driving wheel end, braking effect is better.
Further, described friction head is memory metal friction head, and the friction plate on the friction plate of the second described geared end and braking brake pad is memory metal friction plate.Memory metal is also referred to as memory alloy, utilize some alloy rule that its crystalline structure changes with temperature when solid-state, such as, Ni-Ti alloy more than 40 DEG C and 40 DEG C below crystalline structure be different, but when temperature changes about 40 DEG C, alloy will contraction or expansion, and its form is changed.Therefore, memory metal is coated on the surface of metal friction head, after material friction is out of shape, original shape can be returned to, thus reduce the number of times changing friction head or friction plate.
Further, described friction belt skin is attached with memory metal friction layer.Same reason, friction belt also can adhere to memory metal friction layer outward, thus reduces the replacing number of times of friction belt.
Further, the end being positioned at brake rod of described brake spring is provided with the adjusting nut offseted with spring.Adjusting nut can be used for the pulling force of adjustable brake spring, thus changes the dynamics of braking, and applicability is strong.
