Abstract
The utility model discloses a choke plug, which solves the problems that the conventional choke plug cannot realize finish machining, has unbalanced weight and is difficult to level after being installed. The choke plug comprises a choke plug body, and a shaft hole is formed in the axis of the choke plug body. The choke plug is characterized in that the choke plug body is cylindrical, two end faces of the choke plug body are planar, and the side wall of the choke plug body is provided with at least one annular groove. The annular groove is formed in the radial direction of the choke plug body, so that the choke plug is convenient to machine, and the choke plug body can be subjected to unbalanced weight adjustment and leveling; and by adopting the structure, the weight of the choke plug body can be lightened, and the burden of equipment is lightened.
Description
Technical field
The utility model relates to silently a kind of, and it is silently high specifically can to process balance.
Background technology
The roll shaft that uses in the paper industry at present is for the ease of being fixed on the axle, usually add silently at the roll shaft two ends, by silently being connected with axle, add simultaneously and silently can also play the problem of adjusting whole roll shaft center of gravity, improve and lay particular stress on phenomenon, but at present silently used, as shown in Figure 1, be respectively equipped with scalloped recess in silently both ends of the surface, increase lead at the position of groove, adjust the problem of laying particular stress on.But owing to silently adopt casting technique, casting silently both ends of the surface out can't be carried out fine finishining like this, silently rough surface adds the casting technique built-in problem, cause silently itself laying particular stress on, be installed to again the problem that lays particular stress on that can increase the weight of roll shaft on the roll shaft, even adjust and to reach good effect by increasing lead, also can increase the quality of roll shaft, in use can reduce the service life of equipment, affect the quality of production.
The utility model content
It is silently a kind of that the purpose of this utility model is to provide, and solving tradition silently can't fine finishining, itself exists and lays particular stress on phenomenon, is difficult for the problem of levelling after the installation.
The technical scheme that its technical problem that solves the utility model adopts is: silently a kind of, comprise silently body, silently place, the axle center of body is provided with axis hole, it is characterized in that, described silently body is cylindric, silently the both ends of the surface of body are the plane, and silently the sidewall of body is provided with at least one annular groove.
The beneficial effects of the utility model are: by being provided with annular groove in body radial direction silently, so that silently be convenient to processing, can be before installation body be silently laid particular stress on the adjustment levelling, adopt simultaneously this structure can also alleviate the silently weight of body itself, alleviate facility load.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1 body silently, 2 axis holes, 3 annular grooves.
The specific embodiment
As shown in Figure 2, silently a kind of, comprise silently body 1, silently place, the axle center of body 1 is provided with axis hole 2, and described silently body 1 is cylindric, and silently the both ends of the surface of body 1 are the plane, and silently the sidewall of body 1 is provided with at least one annular groove 3.Silently after body 1 casting well, outer surface is very coarse, and there is the problem that lays particular stress in itself, because the edge silently radial direction of body 1 is provided with annular groove 3, be convenient to like this body 1 is silently carried out fine finishining, can improve the problem of laying particular stress on, simultaneously also can alleviate the silently weight of body 1 like this, silently be installed into roll shaft after the body 1 weight levelling, the impact of roll shaft is less, roll shaft is laid particular stress on when processing again, can silently in axial direction punch on the body 1, carry out the weight balancing by in the hole, putting into lead, because silently body 1 radial section is circular, therefore the position of punching can be on the optional position of circumference, and balancing is more flexible like this.
Claims (1)
- One kind silently, comprise silently body, silently the axle center of body place is provided with axis hole, it is characterized in that described silently body is cylindric, silently the both ends of the surface of body are the plane, silently the sidewall of body is provided with at least one annular groove.
