Abstract

The utility model discloses an adjustable spherical outside surface bearing housing; the bottom part of the bearing housing is provided with a mounting plane (1); the middle is a bearing hole (7) for arranging the spherical bearing; the two sides of the bearing housing are provided with notches (3) for loading and unloading the spherical bearing; the top part of the bearing housing is provided with a salient part (4); the middle of the salient part (4) is provided with a gap (6) which is communicated with the bearing hole (7); a thread hole vertical to the gap (6) is arranged on the salient part (4) as well; a bolt (2) is arranged in the thread hole; a locknut (5) is arranged on the bolt (2); and the inner side of the locknut (5) props against the salient part (4). The adjustable spherical outside surface bearing housing leads the aperture of the bearing hole to be lightly adjusted by an adjusting bolt, thereby eliminating the clearance between the bearing and a bearing shell, leading the bearing to be more stable during running, reducing vibration and noise as well as prolonging the service life of the bearing. When the bearing housing is processed, as the aperture of the bearing hole can be adjusted, the tolerance of the bearing hole can be properly amplified, thus being beneficial to reducing waste products, and reducing the production cost.

Description

Adjustable bearing with spherical outside surface seat

Technical field

The utility model relates to the bearing support field, relates in particular to a kind of adjustable bearing with spherical outside surface seat of placing spherical bearing.

Background technique

The aperture of the bearing hole of existing bearing with spherical outside surface seat is fixed.Because of there is machining error man-hour in its aperture adding, too tight or too loose phenomenon can appear behind running in bearings, then assemble difficulty as tension, as cross pine then between bearing and the cartridge housing gap big, make galloping, noise increases.Thereby the processing request of bearing hole is very high, occurs waste product easily.

Summary of the invention

The purpose of this utility model provides and a kind ofly can guarantee that bearing operation is steady, and can reduce the adjustable bearing with spherical outside surface seat of vibrations and noise.

The technological scheme that realizes above-mentioned purpose is: a kind of adjustable bearing with spherical outside surface seat, the bottom of bearing support is a mounting plane, middle for placing the bearing hole of spherical bearing, the both sides of bearing support have the notch of loading and unloading spherical bearing, the top of bearing support has convex portion, the centre of this convex portion has the breach that communicates with bearing hole, also be drilled with the tapped hole vertical on the convex portion with breach, bolt is installed in the tapped hole, locking nut is installed on the bolt, and the inboard of locking nut props up convex portion.

After adopting technique scheme, convex portion connects by bolt, as long as turn bolt, just can make the middle breach that communicates with bearing hole of convex portion make trace and shrink or expand, make the adjustment of the aperture work trace of bearing hole, thereby adapt to the needs of bearing outside diameter, eliminate the gap between bearing and the cartridge housing, make bearing more steady in the running, and can reduce vibrations and noise, prolong the working life of bearing.During the machining bearing seat, adjustable because of the aperture of its bearing hole, the tolerance of bearing hole can suitably be amplified, and helps reducing waste product, thereby reduces production costs.

Embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail.

Shown in Fig. 1～3, a kind of adjustable bearing with spherical outside surface seat, the bottom of bearing support is a mounting plane 1, middle for placing the bearing hole 7 of spherical bearing, the both sides of bearing support have the notch 3 of loading and unloading spherical bearing, notch 3 can make things convenient for the loading and unloading of bearing, the top of bearing support has convex portion 4, the centre of this convex portion 4 has the breach 6 that communicates with bearing hole 7, also be drilled with the tapped hole vertical on the convex portion 4 with breach 6, bolt 2 is installed in the tapped hole, locking nut 5 is installed on the bolt 2, the inboard of locking nut 5 props up convex portion 4.

Working procedure of the present utility model is as follows: during use, by regulating bolt 2 breach in the middle of the convex portion 46 is supportted more greatly, bearing is just put into easily or is unloaded, pack into behind the bearing, tight a bolt 2, bearing hole 7 is shunk, to eliminate the gap between bearing and the cartridge housing 8, after adjusting, tighten locking nut 6, prevent that bolt 2 is loosening.

Claims (1)

1, a kind of adjustable bearing with spherical outside surface seat, the bottom of bearing support is mounting plane (1), middle for placing the bearing hole (7) of spherical bearing, the both sides of bearing support have the notch (3) of loading and unloading spherical bearing, it is characterized in that: the top of bearing support has convex portion (4), the centre of this convex portion (4) has the breach (6) that communicates with bearing hole (7), also be drilled with on the convex portion (4) and the vertical tapped hole of breach (6), bolt (2) is installed in the tapped hole, locking nut (5) is installed on the bolt (2), and the inboard of locking nut (5) props up convex portion (4).
