Abstract
The utility model relates to a kind of limit power coupling, the spaced steel-ball groove that several concave of tool on the interface of the left semi-coupler of this coupling, between two between steel-ball groove by with on interface radially concave and the chute of arc connects; Right semi-coupler has the through hole corresponding with steel-ball groove, is provided with steel ball between one end of through hole and steel-ball groove, in through hole, is provided with spring, in the other end of through hole, gland nut is installed.Adopt the utility model, can first when maximum power limitation, the gland nut time the tightest progressively be unclamped, until coupling locks gland nut after there is skidding.Therefore, in power limitation, coupling can work, once exceed power limitation, coupling there will be skidding, stops feed, guarantees that equipment is not damaged, if and coupling does not change when finding to load power, illustrate that flow be changed or be starched to abrasive disc will, new change appears in concentration, thus ensure the stable of production, equipment operates steadily.
Description
Technical field
The utility model relates to a kind of limit power coupling, is used in particular for the pulping machine of papermaking.
Background technique
At present, the three-jaw coupling of the pulping machine delivering gear used in paper making process, usual employing power limitation control, delivering gear is the feed of worm gear secondary transmission, after setting pulp beating power, owing to entering to starch concentration, flow changes, the factors such as abrasive disc wearing and tearing, mill district coefficient of internal friction is caused to diminish, particularly after roll flute polishes, dull and stereotyped friction factor is very little, the information of feedback to the computer is that moment of torsion is not enough, fail to reach setting power, the command request that computer provides feed all the time, because two half-couplings of three-jaw coupling are tightly connected to a fixed, therefore, until whole delivering gear holding down bolt all stretches, or just can stop feed after outer casing rupture, equipment accident will be caused.
Summary of the invention
The purpose of this utility model is to provide the one limit power coupling according to power adjustment gland nut elasticity.
The technological scheme that the utility model is taked is: a kind of limit power coupling, comprise left semi-coupler and right semi-coupler, it is characterized in that the spaced steel-ball groove that several concave of tool on the interface of left semi-coupler, between two between steel-ball groove by with on interface radially concave and the chute of arc connects; Right semi-coupler has the through hole corresponding with steel-ball groove, is provided with steel ball between one end of through hole and steel-ball groove, in through hole, is provided with spring, in the other end of through hole, gland nut is installed.
Adopt the utility model, first computer can be demonstrated maximum power limitation, then the gland nut time the tightest is progressively unclamped, until when skidding appears in coupling, then lock gland nut.Therefore, in the power limited, coupling can work, once exceed power limitation, coupling there will be skidding, stops feed, guarantees that equipment is not damaged, if and coupling does not change when finding to load power, illustrate that abrasive disc has arrived replacing construction or new change appears in slurry flow, concentration, thus can ensure to produce stable, equipment operates steadily.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the front view of left half-coupling of the present utility model.
Fig. 3 is the front view of right half-coupling of the present utility model.
In figure, sequence number represents: left half-coupling 1, steel-ball groove 2, steel ball 3, spring 4, through hole 5, gland nut 6, right half-coupling 7 and chute 8.
Embodiment
Below in conjunction with specific embodiment, model utility is described further.
With reference to Fig. 1, Fig. 2 and Fig. 3, this limit power coupling comprises left semi-coupler 1 and right semi-coupler 7, spaced six the spherical steel-ball grooves 2 concaved of tool on the interface of left semi-coupler 1, between two between steel-ball groove 2 by with on interface radially concave and the chute 8 of arc connects; Right semi-coupler 7 has the through hole 5 corresponding with steel-ball groove 2, is provided with steel ball 3 between one end of through hole 5 and steel-ball groove 2, in through hole 5, is provided with spring 4, gland nut 6 is installed in the other end of through hole 5.
During use, first computer can be demonstrated maximum power limitation, again gland nut 6 is screwed onto the tightest, then keep power limitation constant, progressively unclamp gland nut 6, until when right half-coupling 7 has just occurred skidding on left half-coupling 1, when namely steel ball 2 can slide just in chute 8, then lock gland nut 6.Therefore, in the power limited, coupling can work, once exceed power limitation, coupling there will be skidding, and pulping machine stops feed, guarantees that equipment is not damaged, if and coupling does not change when finding to load power, illustrate that abrasive disc has arrived replacing construction or new change appears in slurry flow, concentration, thus can ensure to produce stable, equipment operates steadily.
