Abstract

This device is including the yoke, the front end of yoke is connected with joint bearing's outer lane, circle in the joint bearing and install down the fluted disc, the yoke with the last fluted disc that comprises armature is installed to the corresponding position of fluted disc down, upward be equipped with the ring gear of mutual correspondence on fluted disc and the lower fluted disc opposite face, it is connected with the yoke through a plurality of compression spring to go up the back of fluted disc, compression spring gives thrust of keeping away from the yoke of last fluted disc for go up the motion of the downward fluted disc direction of fluted disc and mesh with lower fluted disc, excitation coil is installed to the yoke front end. The utility model has the characteristics of simple structure, connect stable, the energy resource consumption is little, long service life etc, be applicable to medical for operating room low -spin occasion such as tower crane.

Description

A kind of castellated electromagnetic clutch brake joint shaft bearing
Technical field
The utility model relates to a kind of castellated electromagnetic clutch brake joint shaft bearing, is applicable to the low speed rotation occasions such as medical surgery room tower crane, produces the braking compared with large torque when needing to stop.
Background technique
The existing braking to joint shaft bearing generally all adopts friction disk type to brake, the pressure that main dependence spring or other pushing device produce produces frictional force by friction plate, if the moment of torsion that joint shaft bearing produces is larger, that frictional force needing friction plate to produce is larger, pressure between friction plate just needs larger, if what be therefore with movable friction plate is magnetic clutch, then high with the power requirements of the power plant driving magnetic clutch to magnetic clutch, if and employing cylinder or other pushing device complete clutch, then to the power of cylinder or other pushing device and stability requirement high, such one side energy consumption is larger, make the working life of device short on the other hand.
Model utility content
The purpose of this utility model be to overcome the deficiencies in the prior art and provide that a kind of structure is simple, stable connection, energy consumption are little, the castellated electromagnetic clutch brake joint shaft bearing of long service life.
To achieve these goals, the technological scheme that the utility model adopts is:
A kind of castellated electromagnetic clutch brake joint shaft bearing, comprise yoke, the front end of described yoke is connected with the outer ring of joint shaft bearing, the inner ring of described joint shaft bearing is provided with lower tooth disk, described yoke is being provided with described lower tooth disk corresponding position the upper fluted disc be made up of armature, described upper fluted disc and lower tooth disk opposing side are provided with mutually corresponding gear ring, the back side of described upper fluted disc is connected with yoke by multiple Compress Spring, described Compress Spring gives upper fluted disc thrust away from yoke, make fluted disc to the motion of lower tooth disk direction and engage with lower tooth disk, described yoke front end is provided with field coil.
Described yoke is provided with a hole and is communicated with the back side of upper fluted disc, is installed with the adjusting screw of the spacing regulating upper and lower fluted disc in described silk hole.
Described Compress Spring comprises small one and large one two Compress Springs suit of diameter and forms.
Be wrapped with ferrite resistance magnetic film in described yoke or be coated with ferrite resistance magnetic coating.
Owing to adopting such scheme, the utility model produces torque by the anti-shearing stress of end-tooth during upper lower tooth disk engagement, thus joint shaft bearing is braked, the effect of Compress Spring is just used as thrust less to one of upper fluted disc when upper lower tooth disk engages, thus the power needed is less, stable connection, this device can regulate the spacing between upper lower tooth disk by adjusting screw, thus suitable spacing can be selected according to different voltage, the Compress Spring of this device adopts size spring suit, such one side adds spring force, save space on the other hand, reduce processing cost, ferrite class resistance magnetic film/coating effectively can prevent magnetic field magnetic force loss, strengthen the suction of break magnetic core, prevent magnetic field to around ring Other Instruments, mechanism circuit produces interference.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, further describe the embodiment of this patent.
As shown in Figure 1, a kind of castellated electromagnetic clutch brake joint shaft bearing, comprise yoke 3, be wrapped with ferrite resistance magnetic film in described yoke or be coated with ferrite resistance magnetic coating 9, the front end of described yoke 3 is connected with the outer ring of joint shaft bearing 4, the inner ring of described joint shaft bearing 4 is provided with lower tooth disk 1, described yoke 3 is being provided with described lower tooth disk 1 corresponding position the upper fluted disc 2 be made up of armature, described upper fluted disc 2 and lower tooth disk 1 opposing side are provided with mutually corresponding gear ring, the back side of described upper fluted disc 2 is connected with yoke 3 by multiple Compress Spring 6, described Compress Spring 6 is set with by small one and large one two Compress Springs of diameter and forms, described Compress Spring 6 gives upper fluted disc thrust away from yoke 3, make fluted disc to the motion of lower tooth disk direction and engage with lower tooth disk, described yoke 3 front end is provided with field coil 5, described yoke 3 is provided with a hole 7 and is communicated with the back side of upper fluted disc, be installed with in adjustment in described silk hole 7, the adjusting screw 8 of the spacing of lower tooth disk.
