Described taper type brake member and recessed taper type brake mount faying face are the conical surfaces; Described recessed taper type brake mount is that steel is made, and the taper type brake member conical surface is the abrasive rubber manufacturing; Conical surface groove is arranged on the male cone (strobilus masculinus) of described taper type brake member; Described conical surface groove has 4; The three-dimensional cone angle of described frustum is 24 °-90 °.
When the utility model stopped operating after the motor outage, the taper type brake member can be pressed on the inner conical surface of recessed taper type brake mount vertically under spring action, and the axle in the reduction box is stopped operating, and reached the brake purpose.
The accompanying drawing title
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model motor structural representation when being rotated counterclockwise.
Fig. 3 is the utility model motor structural representation when turning clockwise.
The symbol of figure and explanation thereof: the 1st, motor, the 2nd, motor shaft, the 3rd, spring, the 4th, trundle, the 5th, taper type brake member, the 6th, recessed taper type brake mount, the 7th, reduction box, the 8th, bearing part, the 51st, hollow small column, the 52nd, deep-slotted chip breaker, the 53rd, frustum, the 54th, conical surface groove, the 55th, travelling gear, the 56th, small column.
Embodiment
Set forth an embodiment of the present utility model below in conjunction with accompanying drawing.A kind of motor shaft 2 of motor 1 and device between the reduction box 7 of being contained in is made up of spring 3, trundle 4, taper type brake member 5, recessed taper type brake mount 6, bearing part 8.Motor shaft 2 is connected with reduction box 7, be recessed taper type brake mount 6 successively between them, taper type brake member 5, spring 3, bearing part 8, the male cone (strobilus masculinus) form fit of the inner conical surface of recessed taper type brake mount 6 and taper type brake member 5, recessed taper type brake mount 6 is fixedlyed connected with reduction box 7 casings, spring 3 one ends are close on bearing part 8 end faces on the motor shaft 2, taper type brake member 5 is to be slidingly matched with motor shaft 2, trundle 4 is arranged on motor shaft 2, taper type brake member 5 is by hollow small column 51, frustum 53, small column 56, travelling gear 55 constitutes, hollow small column 51 1 ends and frustum 53 fuse, the other end is close to spring 3, at hollow small column 51 deep-slotted chip breaker 52 is arranged, conical surface groove 54 is arranged on frustum 53, trundle 4 is arranged on deep-slotted chip breaker 52, frustum 53 other ends and small column 56 fuse.Recessed taper type brake mount 6 is that steel is made, and the conical surface of frustum 53 is by the abrasive rubber manufacturing, on 4 conical surface grooves 54 are arranged, travelling gear 55 fuses with small column 56, travelling gear 55 is connected with reduction box 7.
