Description

A kind of disc

Technical field

The utility model relates to the lubrication accessory of pump apparatus bearing, is specifically related to a kind of disc.

Background technique

In the installation of multistage centrifugal pump; in order to ensure the lubrication of bearing; design oil supplying device; the lubricant oil of bearing oil indoor is ensured to be transported to endlessly between sliding bearing and pump shaft; if for shortage of oil; the wearing and tearing of pump shaft and sliding bearing will be caused to aggravate even to damage; disc is exactly lubrication in order to ensure bearing and a kind of mechanical parts designed; the lubricant oil of bearing housing bottom can take on bearing along with the circular movement of axle by it, makes lubricant oil play the effect of lubrication, flushing, cooling, protection bearing.

Disc form structure conventional is at present mainly annular, and its sense of rotation is consistent with the sense of rotation of pump shaft, and drive disc to rotate by pump shaft, lubricant oil takes up the object of getting rid of and playing lubrication to bearing by each surface of disc.In lubrication rotation process, be very easy between disc and rotatingshaft wear and tear, damage can be caused to equipment in the powder access arrangement not only worn and torn, and lubrication amount is also not being met, need to change disc, and disc generally adopts the not high die case zinc of hardness or brass to manufacture, be very easy to distortion, wearing and tearing are caused to rotatingshaft, therefore needs often to change disc.But disc mostly is integral structure at present, and in assembling and dissembling process, needing slings whole rotor assembles, not only change difficulty high, workman's amount of maintenance is large, and material is also extremely wasted.

And be only simply be set on axle or axle journal during disc work, when bearing runs up, disc moves axially increase along axle, and disc is very easy to eject saddle, and impact lubrication, causes the fault of stock pump.

Model utility content

In view of this, the utility model provide that a kind of structure is simple, easy accessibility, move axially little, get rid of that oil mass is large, the better disc of lubrication effect.

For solving above technical problem, the technical solution adopted in the utility model is a kind of disc, the annular solid that it can form annulus by several piece shape, connection that size is identical forms, concavo-convex connection is adopted between adjacent two annular solids, one annular solid end face center is provided with groove, another annular solid end face center adjacent with the reeded annular solid end face of band is provided with bump, and bump length is equal with width with the degree of depth of groove with width, and bump loads in groove and connects with clamping bolt; The internal diameter of described annular solid equals the 1.4-1.6 of the diameter of installed bearing doubly; Described annular solid outer surface is provided with and severally gets rid of oil groove.Preferably, the utility model disc is made up of 2 to 3 pieces of annular solids.

Further, the width of above-mentioned bump is the half of annular solid width.

Further, above-mentioned clamping bolt is 2, and installation direction is parallel to each other on the contrary, enhances the stability connected between annular solid, avoids the connection caused because of mechanical vibration and to come off situation.

Further, above-mentioned annular solid internal surface is zigzag fashion, strengthens the frictional force of bearing and disc internal surface, not only further reduce moving axially of disc, and can more lubricant oil be taken on axle, make pump shaft and sliding bearing lubricating fully, reduce lubrication temperature.

Further, the cross section of above-mentioned annular solid is trapezoidal, is convenient to throw away taking up lubricant oil, increases ring body exterior surface and amasss, and increases band oil mass.

The internal diameter of above-mentioned annular solid equals 1.5 times of the diameter of installed bearing.

Above-mentioned annular solid adopts gunmetal compressing, the wear resistance of bronze is more much better than brass, larger than brass disc frictional force etc. the bronze disc of quality, running speed is high, be with oily ability good, therefore change brass material into gunmetal material, not only increase wear resistance, also improve lubricating ability.

The utility model changes the integral structure of disc into split type annular solid linkage structure, adopt male-female engagement to connect between two annular solids, structure is simple, stable connection, easy to operate, need not remove and reinstall more component when changing disc, reduce pump and repair workload, shorten pump and repair the time, time saving and energy saving, can according to the degree of wear of annular solid change corresponding annular solid when changing disc simultaneously, not need to change whole disc, save material; The utility model specify that the matching relationship between disc and bearing simultaneously, the internal diameter of disc makes the area of contact of disc internal surface and axle reach best when being the 1.4-1.6 times of bearing diameter, accelerating same band oil mass and the lubricating ability that can improve disc of running speed, the force of rolling friction between disc and axle journal can be increased again, reduce moving axially of disc; The setting that simultaneously annular solid outer surface gets rid of oil groove also can improve band oil mass, improves lubrication effect.

Embodiment

In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with embodiment, the utility model is described in further detail.

See Fig. 1, Fig. 2, the utility model provides a kind of disc, it is block-shaped by 3, the annular solid 1 that the connection that size is identical can form annulus forms, concavo-convex connection is adopted between adjacent two annular solids, and fixed by clamping bolt, the annular solid end face center that is specially is provided with groove 11, another annular solid end face center adjacent with the reeded annular solid end face of band is provided with bump 12, the length of bump 12 is equal with width with the degree of depth of groove 11 with width, the width of preferred bump 12 is the half of annular solid 1 width, bump 12 is loaded in groove 11 and connect with clamping bolt 13, preferred employing two clamping bolts connect, and installation direction is parallel to each other on the contrary, enhance the stability connected between annular solid, avoid the connection caused because of mechanical vibration to come off situation.

The internal diameter of above-mentioned annular solid 1 equals the 1.4-1.6 of the diameter of installed bearing 2 doubly simultaneously, is preferably 1.5 times; Described annular solid outer surface 16 is provided with and severally gets rid of oil groove 14.

Preferably, above-mentioned annular solid internal surface 15 is zigzag fashion, strengthens the frictional force of bearing and disc internal surface, not only further reduce moving axially of disc, and can more lubricant oil be taken on axle, make pump shaft and sliding bearing lubricating fully, reduce lubrication temperature.

Below be only preferred implementation of the present utility model, it should be pointed out that above-mentioned preferred implementation should not be considered as restriction of the present utility model, protection domain of the present utility model should be as the criterion with claim limited range.For those skilled in the art, not departing from spirit and scope of the present utility model, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
