Description
Technical field
The present invention relates to a kind of lever brake type motor, it is made up of motor and lever stop.
Background technology
Lever brake type motor generally comprises motor and electromagnetic brake, electromagnetic brake includes electric magnet and brake scotch, and during motor energising, magnet spool is energized simultaneously, making brake scotch separate with the main shaft of motor by lever electromagnetic actuation, motor is freely rotatable.During power-off, electromagnet suction disappears, and a spring makes brake scotch hold main shaft tightly by lever, the rapid stall of motor.The lever brake type motor of this kind of structure, volume is big, manufacturing cost is high.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of lever brake type motor, this lever brake type motor, and braking is reliable, compact conformation, it is possible to decrease manufacturing cost.
Described lever brake type motor, it includes main shaft 1, support 3, drive end bearing bracket 2, rear end cap 6, drive end bearing bracket, rear end cap is connected with support, main shaft is supported on drive end bearing bracket and rear end cap by bearing 10, it is characterized in that, connect on described rear end cap and have electric magnet 7, electric magnet is made up of round table-like magnetic conductor 8 and coil 9, the table top of magnetic conductor is provided with the recess accommodating coil, the cylinder of magnetic conductor is cased with sucker 12, sucker can only be axially moveable on cylinder, it is provided with disk spring 11 between the table top and the left surface of sucker of magnetic conductor, the right flank of sucker is provided with multiple pin rod 13 the most symmetrically, right-hand member at main shaft is provided with brake disc 14, multiple teeth portion it is provided with symmetrically on the circumference of brake disc, described pin rod can insert between adjacent teeth portion.
The braking principle of this lever brake type motor is, produces electromagnetic force, make sucker move towards magnetic conductor when coil obtains electric between magnetic conductor and sucker, and pin rod leaves the teeth portion of brake disc, and main axis is freely；During coil losing electricity, the electromagnetic force between magnetic conductor and sucker disappears, and sucker is pushed to brake disc by disk spring, and the pin rod on sucker inserts between the teeth portion of brake disc, and main shaft can not rotate.The brake structure of this lever brake type motor is simple, and braking is reliable.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the A direction view of Fig. 1, it is shown that the pin rod on sucker inserts the situation between the teeth portion of brake disc.
Accompanying drawing mark represents respectively: 1-main shaft, 2-drive end bearing bracket, 3-support, 4-stator, 5-rotor, 6-rear end cap, 7-electric magnet, 8-magnetic conductor, 9-coil, 10-bearing, 11-disk spring, 12-sucker, 13-pin, 14-brake disc, 15-rubber sleeve.
Detailed description of the invention
The detailed description of the invention of the present invention is described in conjunction with accompanying drawing.
A kind of lever brake type motor, it includes main shaft 1, support 3, drive end bearing bracket 2, rear end cap 6, and drive end bearing bracket, rear end cap are connected with support, and main shaft passes through bearing 10 and is supported on drive end bearing bracket and rear end cap.
Connecting on rear end cap and have electric magnet 7, electric magnet is made up of round table-like magnetic conductor 8 and coil 9, and the right-hand member at magnetic conductor extends a flange, and flange is provided with multiple through hole, with bolt through through hole, is fixed on rear end cap by magnetic conductor.
Being provided with recess on the table top of magnetic conductor, coil is installed in recess.
Being cased with sucker 12 on the cylinder of magnetic conductor, the mesopore of sucker and the cylinder of magnetic conductor can be spline fitted assembling, and the mesopore of sucker and the cylinder of magnetic conductor are alternatively key pins assembling, make sucker can only be axially moveable on cylinder and can not rotate.
Between the table top and the left surface of sucker of magnetic conductor, it is provided with disk spring 11, the right flank of sucker is provided with multiple pin rod 13 the most symmetrically；The right-hand member of main shaft passes from the hole of magnetic conductor, and the right-hand member at main shaft is provided with brake disc 14, and the circumference of brake disc is provided with multiple teeth portion, described pin rod and teeth portion symmetrically, and its quantity is equal；Pin rod can be inserted between adjacent teeth portion.
Described magnetic conductor and sucker are made up of low-carbon steel material, and mild steel has higher permeability.
The braking principle of this lever brake type motor is, produces electromagnetic force, make sucker move towards magnetic conductor when coil obtains electric between magnetic conductor and sucker, and pin rod leaves the teeth portion of brake disc, and main axis is freely；During coil losing electricity, the electromagnetic force between magnetic conductor and sucker disappears, and sucker is pushed to brake disc by disk spring, and the pin rod on sucker inserts between the teeth portion of brake disc, and main shaft can not rotate.The brake structure of this lever brake type motor is simple, and braking is reliable.
It is to reduce the brake disc impact to pin rod during braking, pin rod overlaps rubber sleeve 15.
