Abstract
The utility model discloses a novel rack baring box, wherein two conical roller bearings are placed inside a bearing seat; and the inner rings of the two conical roller bearings are sleeved on a shaft sleeve, and are limited through a round nut and steps on the shaft sleeve. The novel rack baring box is characterized in that the two conical roller bearings are arranged opposite to the large end surface of outer rings; and a limit boss is arranged on the bearing seat between the two outer rings. The novel rack bearing box is scientific in design and convenient to adjust, so that axial floating of the shaft sleeve is effectively prevented, the service life of the bearing box is prolonged, and the working condition of equipment spindle is ensured.
Description
Technical field
The utility model relates to a kind of mechanical fitting, relates in particular to a kind of rack bearing box.
Background technique
The main shaft of some equipment axially, radially all has certain load, and the radial force direction changes, and this just requires the structure that adopts the double cone roller bearing to coordinate in bearing box.As shown in Figure 1, two tapered roller bearings 2 in this class bearing box in the past arrange in the relative mode of inner ring 6 large end faces, two inner rings 6 are limited on axle sleeve 7 by the step 8 of round nut 9 and axle sleeve 7 one ends, outer ring 5 limits by bearing support 1 and gland 4 respectively, be provided with between gland 4 and corresponding outer ring 5 and adjust pad 3, the play of tapered roller bearing 2 is by adjusting the THICKNESS CONTROL of pad 3, play is regulated comparatively trouble, the THICKNESS CONTROL of adjusting pad 3 is improper, affects the operating life of bearing and the working state of main shaft.
The model utility content
For overcoming above-mentioned technical problem, the utility model provides a kind of design science, the new frame bearing box that the tapered roller bearing play is easy to adjust.
For realizing above-mentioned technical purpose, the utility model is by the following technical solutions: a kind of new frame bearing box, be placed with two tapered roller bearings in bearing support, the inner ring of two tapered roller bearings is nested with on axle sleeve, and limit by the step on round nut and axle sleeve, it is characterized in that: two tapered roller bearings arrange in the relative mode of the large end face of outer ring, and bearing support is provided with a positive stop lug boss between two outer rings.
The utlity model has following beneficial effect: it is on former bearing box basis, two tapered roller bearing positions are exchanged, make the large end face of inner ring be positioned at the outside, can regulate easily play between inner ring, outer ring by the round nut on axle sleeve, just make tapered roller bearing reach optimum Working as long as round nut is tightened backward time pine half button.Its design science, easy to adjust, effectively avoid the axle sleeve axial float, extended the working life of bearing box, guaranteed the working state of machine spindle.

Fig. 2 is the utility model structural representation.
In figure, 1, bearing support, 2, tapered roller bearing, 3, adjust pad, 4, gland, 5, the outer ring, 6, inner ring, 7, axle sleeve, 8, step, 9, round nut, 10, positive stop lug boss.
Embodiment
Referring to shown in Figure 2, the inner ring 6 that is placed with two tapered roller bearing 2, two tapered roller bearings 2 in bearing support 1 is nested with on axle sleeve 7, and inner ring 6 outsides limit by the step 8 on round nut 9 and axle sleeve 7 respectively; Two tapered roller bearings 2 arrange in the relative mode of the large end face of outer ring 5, bearing support 1 is provided with a positive stop lug boss 10 between two outer rings 5, the large end face of two outer rings 5 limits the position by positive stop lug boss 10, can regulate working clearance between inner ring 6, outer ring 5 by the position of adjusting round nut 9.Owing to being provided with positive stop lug boss 10 between two outer rings 5, therefore bearing support 1 adopts the both ends open design, two ends are provided with gland 4, in order to will add man-hour, tapered roller bearing 2 are put into bearing support 1.
Claims (2)
1. new frame bearing box, be placed with two tapered roller bearings in bearing support, the inner ring of two tapered roller bearings is nested with on axle sleeve, and limit by the step on round nut and axle sleeve, it is characterized in that: two tapered roller bearings arrange in the relative mode of the large end face of outer ring, and bearing support is provided with a positive stop lug boss between two outer rings.
2. a kind of new frame bearing box as claimed in claim 1 is characterized in that: bearing support adopts the both ends open design, and two ends are provided with gland.
