Abstract
The invention discloses an improved structure of a tubular motor braking device. The improved structure comprises a brake shell; a brake disc, an armature, an electromagnet are sequentially arranged in the brake shell from front to back; a manual brake device connected with the rear part of the armature is arranged on the brake shell; the manual brake device comprises a steel wire rope, a front handle and a rear handle; the rear end of the front handle is connected with a thread of the rear handle; one end of the steel wire rope is fixed at the rear part of the armature; the other end of the steel wire rope penetrates through the front handle and then is fixed on the rear handle; and the steel wire rope is sleeved with a spring between the armature and the electromagnet. In the invention, the rotary manual brake device is added on the basis of automatic braking of the original armature and the brake disc to ensure mechanical operation of a gate piece during power off.
Description
Technical field
The present invention relates to dynamic braking device.
Background technique
General tube shaped electric machine has all been realized Braking mode, be that 200510097028.2 Chinese utility model patent discloses tube shaped electric machine brake device on June 28th, 2006 as the patent No., comprise the rotor assembly that is fitted in the motor housing chamber, motor stator component, brake assembly, brake assembly includes brake spring and brake assemblies, this brake spring is sleeved on the rotor shaft upper pole part of rotor assembly, brake assemblies comprises that the merging that matches has the following brake assemblies and the last brake assemblies of braking brake effect, following brake assemblies is embedded with metallic iron, rotor shaft upper boom bottom is nested with motor shaft and inhales iron component, this motor shaft is inhaled the upper-end surface of iron component lower end surface applying rotor, the magnetic force that motor shaft suction iron component utilizes rotor to produce will descend the metallic iron adhesive in the brake assemblies, and following brake assemblies compression brake spring breaks away from goes up brake assemblies.Its magnetic field that utilizes motor when energising itself to produce goes that brake assemblies makes brake separate motor rotation under the adhesive, but the braking after it can not guarantee to have a power failure.
Summary of the invention
Technical problem to be solved by this invention just provides a kind of tube shaped electric machine braking device and improves structure, guarantees that power failure back door sheet can also be mechanically operated by braking.
For solving the problems of the technologies described above, the present invention adopts following technological scheme: a kind of tube shaped electric machine braking device improves structure, comprise brake casing, be provided with brake disc, armature, electromagnet in the described brake casing from front to back successively, it is characterized in that: also be provided with on the described brake casing and the back-connected manual braking device of armature.
Preferably, described manual braking device comprises wire rope, front handlebar, back handle, and described front handlebar rear end is threaded with the back handle, and described wire rope one end is fixed on the armature rear portion, and the wire rope the other end passes described front handlebar and is fixed on the handle of described back.
Preferably, be with the wire rope sheath on the described wire rope.
Preferably, described wire rope is gone back socket one spring between armature and electromagnet.Spring is the distance of regulating between control armature and the electromagnet.
Preferably, described brake casing is fixedly formed by break front case and break bolt of rear case, and described brake disc and armature are located in the break front case, and described electromagnet is located in the break rear case.
The present invention has increased the rotating type manual braking device on the basis of original armature and brake disc Braking mode, guaranteed that power failure back door sheet can also be mechanically operated by.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is further described:
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1, improve the embodiment of structure for a kind of tube shaped electric machine braking device of the present invention, comprise brake casing, be provided with brake disc 28, armature 30, electromagnet 32 in the described brake casing from front to back successively, also be provided with on the brake casing and the back-connected manual braking device of armature.Described manual braking device comprises wire rope 36, front handlebar 35, back handle 37, described front handlebar rear end is threaded with back handle 37, described wire rope 36 1 ends are fixed on the armature rear portion, and the wire rope the other end passes described front handlebar and is fixed on the handle of described back.Be with wire rope sheath 34 on the described wire rope.Described wire rope is gone back socket one spring 31 between armature and electromagnet.Described brake casing is formed by break front case 29 and break rear case 33 bolt, and described brake disc and armature are located in the break front case, and described electromagnet is located in the break rear case.
The principle of Braking mode is: at power down mode, armature abuts against with brake disc, and the resistance that the friction plate on armature and the brake disc produces makes brake disc locked.When motor is switched on, produce electromagnetic force, make armature break away from brake disc and electromagnetic actuation, motor running; When stopping to switch on, electromagnetic force disappears, and armature and electromagnet break away from.
The principle of hand brake is: front handlebar (band silk screw thread) and back handle (band silk internal thread) internal and external threads close tight, in the time will spurring steel cable, as long as make it towards breaking away from back handle hand of spiral motion the front handlebar rotation, wire rope will be tightened up, otherwise wire rope can loosen.
