Abstract
The invention provides a shaft separation-type safety motor. The shaft separation-type safety motor comprises a rotating shaft, a stator and a casing; the rotating shaft comprises a fixed rotating shaft and a moving rotating shaft; abutting portions of the fixed rotating shaft and the moving rotating shaft are matched with each other, and the circumferences of the abutting portions are wave type convex block-shaped; the other end of the fixed rotating shaft extrudes out from the casing so as to be connected with an equipment input end; the other end of the moving rotating shaft is connected with a shutdown device through a spring; the shutdown device is mounted on the casing and is provided with a shutdown button; and the shutdown button is opposite to one spring-mounting end of the moving rotating shaft, and a gap smaller than 5mm exists between the shutdown button and the spring-mounting end. According to the shaft separation-type safety motor, the fixed rotating shaft and the moving rotating shaft are designed separately, and therefore, the fixed rotating shaft can be separated from the moving rotating shaft when equipment stops rotation, and the shutdown button can be triggered, and the motor can be powered off, and therefore, the burnout of the motor caused by overheating can be avoided.
Description
Affiliated technical field
The present invention relates to technical field of motors, be specifically related to a kind of axle separate type safe motor.
Background technology
Motor is to use electromagnetic principle, electric energy conversion is become to the machinery of kinetic energy, and its inside generally includes motionless stator, and the rotor of output torque; Usually being comprised of the coiling of switching on of stator, rotor mostly is the axle class formation, and after coil electricity, for driving magnetic force is provided for stator, rotor rotates under the effect of magnetic force, torsion is offered to the machinery of demand motive.But when using motor, occur that sometimes some unexpected situations cause the stuck of rotor, as occurred foreign matter on machinery equipment, the transmission of equipment is interrupted, or equipment is not used and gets rusty for a long time; In the situation that these rotors is stuck, the electric current of motor can become greatly, so that larger actuating force to be provided.And, in the situation that motor does not turn, become large electric current can produce more heat, if at this moment motor does not stop the electric current input, the heat gathered can burn out motor circuit, even initiation fire, bring huge hidden danger to people's production and life.
Summary of the invention
For above problem, the invention provides a kind of can be in the situation that external force causes output shaft stuck, autostop with the protection its internal circuit axle separate type safe motor.
The technical solution adopted for the present invention to solve the technical problems is: this axle separate type safe motor comprises rotating shaft, stator, casing, and described stator is relative with casing fixing, and described rotating shaft is output shaft, with relative stator, can be loaded in stator by rotation mode; Described rotating shaft comprises determines two sections of rotating shaft, moving rotating shafts; determining to be affixed position between rotating shaft and moving rotating shaft cooperatively interacts; be circumferentially wave projection shape; describedly determine the rotating shaft other end and stretch out casing and be connected with the equipment input; the described moving rotating shaft other end is connected with arresting gear by spring, and described arresting gear is loaded on casing, and stop botton is housed on it; described stop botton is relative with moving rotating shaft shock mount end position, the middle gap that is less than 5mm that exists.
As preferably, reset button is equipped with in described arresting gear outside.
As preferably, between described moving rotating shaft and stator, adopt sliding bearing to be connected.
Beneficial effect of the present invention is: be divided into and determine two sections of rotating shaft, moving rotating shafts as the rotating shaft of output shaft in this axle separate type safe motor, between with the projection shape connection circumferentially matched for wave, described moving rotating shaft is axle slidably; During the work of this axle separate type safe motor, power is passed in moving rotating shaft by stator, and moving rotating shaft is transmitted given rotating shaft by the projection shape of cooperation place again, finally outputs on equipment.When equipment during because of unexpected stall, with equipment, be connected to determine rotating shaft motionless, moving rotating shaft place torsion becomes large, moving rotating shaft is relatively determined rotating shaft and is outwards done disengaging movement in projection shape junction, the stop botton axle separate type safe motor on the shake-up arresting gear shuts down.This axle separate type safe motor just can be avoided because rotating shaft is stuck like this, and then electric current is excessive, produces too much heat and burns out the situation of machine.
The accompanying drawing explanation
Fig. 1 is the structural representation of axle separate type safe motor.
Fig. 2 is the wave projection shape of determining the rotating shaft axle head.
Fig. 3 is the structural representation when determining rotating shaft, moving rotating shaft in axle separate type safe motor and mutually breaking away from.
Embodiment
Below in conjunction with embodiment, the present invention is further described:
In embodiment, described axle separate type safe motor, comprise rotating shaft 1, stator 2, casing 3 as shown in Figure 1, and described stator 2 is relative with casing 3 fixing, and described rotating shaft 1 is output shaft, relatively can be loaded in stator 2 by rotation mode; Described rotating shaft 1 comprises determines 12 two sections of rotating shaft 11, moving rotating shafts, and determine to be affixed position between rotating shaft 11 and moving rotating shaft 12 and cooperatively interact, be circumferentially wave projection shape, be illustrated in figure 2 the shape of determining rotating shaft 11 axle heads.
As shown in Figure 1, describedly determine rotating shaft 11 other ends and stretch out casing 1 and be connected with the equipment input, described moving rotating shaft 12 other ends are connected with arresting gear 5 by spring 4, described arresting gear 5 is loaded on casing 3, spring 4 is compressed between moving rotating shaft 12 and arresting gear 5, to move rotating shaft 12 is pressed onto and determines in rotating shaft 11, described arresting gear 5 is in parallel with axle separate type safe motor main circuit, stop botton 51 is housed on it, cut-offfing of Control Shaft separate type safe motor main circuit, described stop botton 51 is relative with moving rotating shaft 12 shock mount 4 end positions, middle this axle of gap that is less than 5mm that exists.During the work of separate type safe motor, power is passed in moving rotating shaft 12 by stator 2, and moving rotating shaft 12 is transmitted given rotating shaft 11 by the projection shape of cooperation place again, finally outputs on equipment.
As shown in Figure 3, described moving rotating shaft 12 is axle slidably; When equipment during because of unexpected stall; with equipment, be connected to determine rotating shaft 11 motionless; moving rotating shaft 12 place's torsion become large; moving rotating shaft 12 is relatively determined rotating shaft 11 and is outwards done disengaging movement in projection shape junction; as Fig. 3 direction of arrow; moving rotating shaft 12 end faces touch the stop botton 51 on arresting gear, and axle separate type safe motor shuts down.This axle separate type safe motor just can be avoided because rotating shaft 1 is stuck like this, and then electric current is excessive, produces too much heat and burns out the situation of machine.
Between described moving rotating shaft 12 and stator, adopt sliding bearing 6 to be connected.Sliding bearing 6 not only can, easily to moving rotating shaft 12 in axial location, can effectively reduce friction simultaneously.
