The present invention relates to brake field, be particularly used for inertia brake one and release brake unit.Including motor and pivotal slide mechanism, described motor is connected with pivotal slide mechanism, and pivotal slide mechanism promotes pressing plate, and pressing plate compression disc spring, keep plate separates with friction plate.The invention has the beneficial effects as follows: use disc spring can bear great load in less space, compare helical spring requisite space less, after pivotal slide mechanism releases brake force, it is not necessary to external force source realizes braking, when motor quits work, it is automatically obtained braking effect.
Description
Technical field
The present invention relates to brake field, be particularly used for inertia brake one and release brake unit.
Background technology
Brake is widely used in all trades and professions, and as a kind of safety component, whole application is had the heaviest by it
The meaning wanted.Conventional brake uses external force source to brake mostly, and when no longer applying external force, brake force releases, in range of application
On have certain limitations.Existing inertia brake driving link is complicated with driven member moulding, installs relatively big with later maintenance workload, and
Helical spring is mostly used to realize braking, owing to unit length helical spring bearing capacity is strong, for reaching certain braking
Effect, it is desirable to number of springs is more or length is relatively big, and shared space is big.
Summary of the invention
It is an object of the invention to provide a kind of releasing brake unit, convenient for installation and maintenance, and braking disc spring takes up room little.
For achieving the above object, the present invention is by the following technical solutions: release brake unit, including motor and rotational slide
Mechanism, described motor is connected with pivotal slide mechanism, pivotal slide mechanism promote pressing plate, pressing plate compression disc spring, keep plate with rub
Pad separates.
Described pivotal slide mechanism includes the driving shaft being connected with motor, and driving shaft is by driving axle housing with drivewheel even
Connecing, be fixed with pressing plate between driving axle housing and drivewheel, driven shaft is connected with driven pulley by driven shaft sleeve, driven pulley and active
Contact site between wheel is corrugated surface, and pressing plate side is provided with disc spring, and opposite side is provided with keep plate, keep plate and friction plate
Contact.
It is the splined shaft coordinated with splined shaft that described driving shaft and driven shaft are splined shaft, driving axle housing and driven shaft sleeve
Set, hub splines is U-shaped set, is provided with installing hole bottom U-shaped set.
Described pressing plate is installed and is connected with pull bar, and pull bar is provided with disc spring, and disc spring is arranged between pressing plate and fuselage, pressing plate
Side contacts with keep plate.
The invention has the beneficial effects as follows: use disc spring can bear great load in less space, compare spiral
Spring requisite space is less, after pivotal slide mechanism releases brake force, it is not necessary to external force source realizes braking, when motor stops work
When making, it is automatically obtained braking effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
As it is shown in figure 1, releasing brake unit, including motor 1, motor 1 is connected with pivotal slide mechanism, utilizes rotational slide
Mechanism urges pressing plate 8, thus compress disc spring 7, make to release on-position when keep plate 9 and friction plate 11 relative movement；Rotate sliding
Motivation structure includes the driving shaft 3 being connected with motor 1, and driving shaft 3 is connected with drivewheel 10 by driving axle housing 4, driving axle housing 4 and
Being fixed with pressing plate 8 between drivewheel 10, pressing plate 8 side is provided with disc spring 7, and opposite side is provided with keep plate 9, keep plate 9 with rub
Pad 11 contacts, and driven shaft 15 is connected with driven pulley 12 by driven shaft sleeve 14, contacting between driven pulley 12 with drivewheel 10
Position is corrugated surface, and the crest of drivewheel 10 fits tightly with the trough of driven pulley 12 in an initial condition, and disc spring 7 is in compression
State, produces thrust between keep plate 9 and friction plate 11；Driving shaft 3 and driven shaft 15 are splined shaft, driving axle housing 4 He
Driven shaft sleeve 14 is the hub splines coordinated with splined shaft, and hub splines is U-shaped set, is provided with installing hole 2 bottom U-shaped set；Pressure
Plate 8 install be connected with pull bar 6, pull bar 6 is provided with disc spring 7, disc spring 7 is arranged between pressing plate 8 and fuselage 5, pressing plate 8 side and
Keep plate 9 contacts.
Use disc spring can bear great load in less space, compare helical spring requisite space less, rotation
After turning slide mechanism releasing brake force, driven pulley is simple with drivewheel moulding, and easy for installation, later maintenance workload is little be need not
External force source realizes braking, when motor quits work, is automatically obtained braking effect.
The work process of the present invention is: under original state, disc spring is in compressive state, applies to make to keep plate by pressing plate
Firmly, between keep plate and friction plate, produce brake force, when motor works, driven by motor actively splined shaft, actively spline
Axle drives actively spline housing, and actively spline housing drives drivewheel to rotate, and the ripple that drivewheel fits tightly originally with driven pulley connects
Contacting surface staggers, and while drivewheel drives driven pulley to rotate, also band dynamic pressure plate produces axial displacement to disc spring side, further
Compression disc spring, now disc spring cannot again by pressing plate to keep plate applying effect, thus release between keep plate and friction plate
Brake force, when motor quits work, drivewheel and driven pulley no longer produce relative motion, and undulated contact surface recovers initial shape
State, the energy that disc spring is compressed is released, by pressing plate to keep plate applying effect again, it is achieved braking effect.
