Abstract
The invention discloses a double-magnetic-circuit electromagnetic clutch and relates to the technical field of clutches. The double-magnetic-circuit electromagnetic clutch comprises a clutch body, wherein a baffle and an armature are mounted in a magnet yoke in the clutch body, six first circumferential grooves are evenly formed in the circumferential direction of the armature, three second circumferential grooves are evenly formed in the circumferential direction of the middle of the baffle, and three third circumferential grooves are formed in the circumferential direction of the baffle and located in the periphery of the second circumferential grooves; when the electromagnetic clutch is well installed, the third circumferential grooves in the baffle are combined with the armature and the magnet yoke to form a first magnetic circuit, the second circumferential grooves in the baffle are combined with the armature and the magnet yoke to form a second magnetic circuit, and then the double magnetic circuits are formed. According to the double-magnetic-circuit electromagnetic clutch, driving torque can be increased on the premise that the size of the clutch is not changed, increasing of driving torque can be achieved without the change of structures for a plurality of motor drive devices with installation space limited, and space for the design of equipment can also be saved.
Description
Technical field
The present invention relates to Clutch Technology field, be specifically related to a kind of double magnetic circuit magnetic clutch of transmission gear for electric motor.
Background technique
When transmission gear for electric motor need to increase driving torque, magnetic clutch must increase electromagnetic force, traditional method is by revising the piece volumes of coil and increase clutch, when transmission gear for electric motor installing space is restricted, clutch after moment increases just cannot be installed, and finally causes motor-driven equipment normally to use.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of practical, quick and easy for installation double magnetic circuit magnetic clutch.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of double magnetic circuit magnetic clutch, comprise a clutch body, baffle plate and armature are installed in the yoke in described clutch body, on described armature, be along the circumferential direction evenly provided with six the first circumferential grooves, in the middle of described baffle plate, be along the circumferential direction evenly provided with three the second circumferential grooves, in described the second circumferential groove periphery, be positioned at and on baffle plate, be along the circumferential direction provided with three the 3rd circumferential grooves.
After magnetic clutch installation, the 3rd circumferential groove on baffle plate and armature and yoke combination, form the first magnetic circuit A; The second circumferential groove on baffle plate and armature and yoke combination, form the second magnetic circuit B, and clutch has just formed double magnetic circuit, has increased the electromagnetic force of armature on the basis that does not change clutch coil and volume, and the driving torque of clutch increases.
The invention has the beneficial effects as follows: use after magnetic clutch of the present invention, can on the constant basis of clutch volume, increase driving torque, in a lot of restricted transmission gear for electric motor of installing space, can accomplish not revise structure can increase driving torque, also can make equipment design conserve space more.
Accompanying drawing explanation
Fig. 1 is clutch assembly figure of the present invention;
Fig. 2 is armature schematic diagram of the present invention;
Fig. 3 is baffle plate schematic diagram of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
As shown in Figure 1-Figure 3, a kind of double magnetic circuit magnetic clutch, comprise a clutch body, baffle plate 20 and armature 10 are installed in the yoke 30 in clutch body, on armature 10, be along the circumferential direction evenly provided with six the first circumferential grooves 101, in the middle of baffle plate 20, be along the circumferential direction evenly provided with three the second circumferential grooves 201, in the second circumferential groove 201 peripheries, be positioned at and on baffle plate 20, be along the circumferential direction provided with three the 3rd circumferential grooves 202.
Magnetic clutch baffle plate 20 has been designed to six circumferential grooves, and armature 10 is designed with six circumferential grooves.After magnetic clutch installation, the 3rd circumferential groove 202 on baffle plate 20 and armature 10 and yoke 30 combinations, form the first magnetic circuit A; The second circumferential groove 201 on baffle plate 20 and armature 10 and yoke 30 combinations, form the second magnetic circuit B, and clutch has just formed double magnetic circuit, has increased the electromagnetic force of armature on the basis that does not change clutch coil and volume, and the driving torque of clutch increases.
More than show and described basic principle of the present invention and major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
