Description
Technical field
The utility model relates to technical field of bearings, more specifically relates to the sliding bearing that a kind of shaft core position is adjustable.
Background technique
Sliding bearing is the supporting member extensively adopted in various transmission device, particularly running up in machinery, in order to reduce friction, improving transmission efficiency, require disengage between sliding bearing and axle journal and there is enough oil slick thickness, to form the Frotteurism between liquid.
The removable metal back of the body of the prior art is a cylndrical surface, and is generally small interference fit between the bearing hole on gear case body.As shown in Figure 1, be exactly a kind of sliding bearing, comprise the tile of two semicircular ring, two tiles are fixed on the positioning by screw and locating stud, then integrally coordinate and are installed in bearing hole.
After this type of sliding bearing installs in bearing hole, be just fixed up in its position, can not adjust.When running into casing bearing hole and being processed with coaxality or position degree deviation, or when other reason needs to adjust shaft core position, need machining shaft bearing bore again, bearing hole processes the increase product cost that both wasted time and energy again, is difficult to control accuracy again.
Model utility content
The utility model, for overcoming above-mentioned deficiency of the prior art, provides the sliding bearing that a kind of shaft core position is adjustable.
The utility model is achieved through the following technical solutions above-mentioned purpose.
The sliding bearing that shaft core position is adjustable, comprises bearing body, and there is radial regulation block under bearing body watt back and/or left and right respectively by screw locking, is provided with spacer shims between regulating block and bearing body.
Sliding bearing in this programme is installed in bearing hole, when bearing hole is processed with coaxality or position degree deviation, or when having other reason to need to adjust shaft core position, can by increasing or reducing spacer shims, or a wherein interblock feeler is taken out and is installed to regulating block place corresponding thereto, thus reorientate the position in axle center, machining shaft bearing bore is again avoided to waste time and energy and be difficult to control accuracy, the expense that time, again machining that saving again machining needs need, reduce cost, fast easy to adjust.
Above-mentioned bearing body is provided with center hole, be provided with two or four mounting planes be evenly arranged around the axle center of center hole at bearing body watt back, and mounting plane is vertical with the diameter of center hole with axis parallel; Above-mentioned regulating block is arc, the string face of regulating block press against spacer shims then by screw locking on mounting plane, the cambered surface of two or four regulating blocks forms the fitting surface that sliding bearing is assembled into bearing hole.
In order to enable sliding bearing accurately adjust, wherein one piece of above-mentioned regulating block is provided with pin-and-hole.In bearing hole corresponding position, also pin-and-hole is set, is then positioned by locating stud.Like this after adjusting the spacer shims of sliding bearing, when sliding bearing reinstalls to bearing hole, can be positioned by locating stud, not need adjustment, the axle center of sliding bearing is directed adjustment.
In order to improve the precision of sliding bearing, above-mentioned regulating block, spacer shims and bearing body are by least two straight pin location.
The thickness of above-mentioned spacer shims is 0.005 ~ 3mm.Spacer shims can adopt ready-made product, and its thickness is a series of fixed value, as 0.005mm, 0.01mm, 0.02mm, 0.03mm ..., do not need like this to produce spacer shims separately, reduce product cost.
The utility model compared with prior art mainly has following beneficial effect: by increasing or reducing spacer shims, or a wherein interblock feeler is taken out and is installed to regulating block place corresponding thereto, thus reorientate the position in axle center, save again time and the expense of machining need, reduce cost, fast easy to adjust; Crucial cooperation position place is positioned by pin-and-hole and detent fit, accurate positioning, improves Product Precision.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.Accompanying drawing, only for exemplary illustration, can not be interpreted as the restriction to this patent.
In order to more succinct explanation the present embodiment, in accompanying drawing or explanation, some well known to a person skilled in the art but can omit to some extent with the incoherent component of the main contents of this creation.In addition for ease of statement, in accompanying drawing, some component has omission, zooms in or out, but does not represent size or the entire infrastructure of actual product.
Embodiment one:
As shown in Figure 2, the sliding bearing that a kind of shaft core position is adjustable, comprises bearing body 1, two regulating blocks 2, spacer shims 3.
Bearing body 1 is provided with the center hole for wearing axle journal, the bearing body 1 of the present embodiment is that two tiles centrally in axle center, hole point fasten and form, a watt back of the body for each tile cuts one arc piece for cylindrical surface, and forms a mounting plane, and mounting plane is parallel with split.
The shape of two regulating blocks 2 is identical, regulating block 2 is arc and excision two wedge angles, the string face of two regulating blocks 2 press against respectively two interblock feelers 3 then by screw locking on mounting plane, the diameter of regulating block 2 cambered surface is greater than the diameter of bearing body 1, and the cambered surface of two regulating blocks 2 forms the fitting surface that sliding bearing is assembled into bearing hole.
In order to enable sliding bearing accurately adjust, wherein one piece of regulating block 2 is provided with pin-and-hole 21.In bearing hole corresponding position, can pin-and-hole be set, be then positioned by locating stud.Like this after adjusting the spacer shims 3 of sliding bearing, when sliding bearing reinstalls to bearing hole, can be positioned by locating stud, not need adjustment, the axle center of sliding bearing is directed adjustment.
In order to improve the precision of sliding bearing, regulating block 2, spacer shims 3 and bearing body 1 are located by two straight pins 4.
The thickness of the spacer shims 3 in the present embodiment is 0.01mm, and feeler can adopt ready-made product around here, does not need like this to produce spacer shims separately, reduces product cost.
Sliding bearing in the present embodiment is arranged in bearing hole, can be located by locating stud, and regulating block about 2 is arranged, when needs make shaft core position move down 0.01mm, take off sliding bearing, as shown in Figure 3, can take out top an interblock feeler 3 and be installed to below regulating block 2 and spacer shims 3 between, and then be again assembled in bearing hole by sliding bearing, thus reach the object that shaft core position moves down 0.01mm.Adopt the sliding bearing in the present embodiment, avoid again wasting time and energy and being difficult to control accuracy during machining shaft bearing bore, save again time and the expense of machining need, reduce cost, fast easy to adjust.
Embodiment two:
The difference of the present embodiment and embodiment one is, as shown in Figure 4, bearing body 1 watt is carried on the back as cylindrical surface cuts two to relative arc piece, form four mounting planes be evenly arranged around center hole axle center, wherein a pair mounting plane is parallel with split, and another is vertical with split to mounting plane.Each mounting plane is installed two interblock feelers 3 and a regulating block 2, thus can by the combination relation its axle center position in two mutually orthogonal directions of adjusting play sheet 3.
These are only two specific embodiments of the present utility model, but design concept of the present utility model is not limited thereto, all the utility model that utilizes conceive the insubstantial modifications made the utility model, all fall within protection domain of the present utility model.
