Description
Technical field
The present invention relates to motor, relate in particular to the motor of a kind of strap brake and overload protection.
Background technology
On hoist engine or shutter door, all can use motor.In order to make object stop at timely and accurately needed position, at motor brake mechanism is set, make motor possess brake function.As in China Patent No. 2004201500158, Granted publication day be February 8 in 2006 day, be called and disclose a kind of motor with brake function in " motor of braking device ".The brake mechanism that motor in this patent documentation comprises the motor body that is made of housing, rotor and stator and is used for rotor is braked.
The motor of existing strap brake has the following disadvantages:
Rotor stopped in moment, so the impact of the inertia motion countershaft of load is large in the process that stops, and caused easily rotating shaft moment overload and the phenomenon generation of fracture;
As all motors; overload protection is finished by electric component such as heat protection; the working method of heat protection is: overload causes Current rise, Current rise to cause heating aggravation, heating aggravation to cause that temperature rises, when temperature rises to above set point then circuit disconnect and stop power supply and produce the protection action.When therefore carrying out overload protection by the heat protection following deficiency is arranged: the temperature rising can cause poor, the poor reliability of aging acceleration, promptness of electric wire and electronic devices and components.
Rotor all is solid, and weight is large, and cost height and control precision are low.
The heat radiation of motor is to finish by the end provided with fan away from load in rotating shaft, and the mode of exterior fan causes structural compactness poor.
Summary of the invention
First purpose of the present invention aim to provide a kind of not only had overload protection function but also can not produce rotating shaft be hit and the strap brake of the phenomenon that fractures and the motor of overload protection, the motor that has solved existing strap brake in braking procedure, the rotating shaft meeting is subject to moment impact and the problem that fractures and undertaken by electric component that the existing meeting of overload protection causes aging acceleration, the promptness of electric wire and electronic devices and components poor, the problem of poor reliability.
Second purpose of the present invention aims to provide a kind of provided with fan that need not can finish the strap brake of heat radiation work and the motor of overload protection; it is large and cause the low problem of control precision both to have solved rotor Heavy Weight, inertia, has solved again the poor problem of structural compactness of dispelling the heat and causing by exterior fan.
Above technical problem solves by following technical proposal: the motor of a kind of strap brake and overload protection; comprise motor body; described motor body comprises internal rotor and with the rotating shaft of internal rotor Joint; motor body is provided with braking mechanism; it is characterized in that; also comprise the fluid pressure type overload protective device; described rotating shaft comprises coaxial driving shaft and driven shaft; described fluid pressure type overload protective device comprises installing rack; bent axle and pair of hydraulic cylinders; be provided with communicating pipe between two cylinder bodies in the pair of hydraulic cylinders; be provided with the bidirection press valve on communicating pipe; described bent axle comprises main shaft and pitman shaft; described main shaft is rotatably connected with described installing rack; described driven shaft is fixed together with described main shaft; described pitman shaft links together with described installing rack by oil cylinder, and described driving shaft one end is fixed together with internal rotor; the other end is fixed together with installing rack." bidirection press valve " refers to can be towards the valve of the low side unlatching of pressure when the pressure differential of spool both sides reaches set point.In the use procedure, load is connected on the driven shaft.When the torsion between driving shaft and the driven shaft reaches when the bidirection press valve is opened, bent axle is with producing relative rotation between the installing rack, also be to produce relative rotation between driving shaft and the driven shaft, when the torsion between driving shaft and the driven shaft is returned to when being lower than the bidirection press valve opening pressure, then bent axle relatively rotates with stopping between the installing rack, also be to recover between driving shaft and the driven shaft to rotate synchronously, thereby play load when excessive and automatically cut off the effect of load.Because of load when excessive rotating shaft meeting automatic disconnection load meet the requirements make and can certainly be dynamically connected on; the phenomenon that therefore can not produce moment impact and cause rotating shaft to fracture produces, motor can not be operated under the overload, be that motor can not produce the overload phenomenon yet; can not produce the electric component that the overload phenomenon then need not to install in electrical control overload protection function, the convenience during electrical control also is improved.
As preferably, described hydraulic cylinder comprises cylinder body and piston rod, and described cylinder body is fixed on the described installing rack, and described piston rod and pitman shaft link together by connecting rod.Overload protective device apparent size can be less.
As preferably, described installing rack comprises left support seat, right support seat and the link that left support seat and right support seat are linked together, left support seat, right support seat and link three surround frame structure, it is inner that described bent axle and hydraulic cylinder are positioned at described installing rack, described main shaft comprises left trunnion and right trunnion, left trunnion is rotatably connected on the left support seat, driving shaft is fixed on the left support seat, right trunnion is rotatably connected on the right support seat, and driven shaft is fixed together with right trunnion.The two ends of bent axle all are rotatably connected on the installing rack, and are convenient during fixed crankshaft, and the stationarity of bent axle when producing relative rotation between the installing rack is good; Cylinder design is for being positioned at installing rack inside, and hydraulic cylinder is difficult for being broken, and improves reliability of the present invention.
