Abstract

The utility model relates to a rolling bearing device of a ball mill group, with a rolling bearing and a vacuum axle easy to install. The technical proposal is that in the rolling bearing device of a ball mill group, an axle box seat with a negative spherical top is arranged in a main axle bow, a bearing tray is arranged in the axle box seat, rolling bearing is arranged on the bearing tray and the rolling bearing supports the vacuum axle, which is characterized in that an inner circle is arranged between the rolling axle and the vacuum axle, the inner circle sets in the vacuum axle, oblique holes are arranged inward in the inner circle axle, a regulating tight set matching with the oblique holes is arranged inside the oblique holes, the regulating tight set is set in the vacuum axle, top wires which can make the regulating tight set move in an axial direction along an outside face of the vacuum axle are arranged in the regulating tight set axial end.

Description

The rolling bearing of ball milling unit

Technical field: the utility model relates to a kind of rolling bearing of ball milling unit.

Background technique: the patent No. 98244746.9 patent disclosures a kind of rolling bearing structure of ball milling unit, its shortcoming be quill shaft and rolling bearing when installing existing quill shaft need change cutter, difficulty is big, increases cost.

The model utility content: the purpose of this utility model is to provide a kind of and the rolling bearing easy-to-install ball milling unit of quill shaft.Technological scheme is, be provided with the axle box seating of top in the headstock for negative sphere shape, be provided with bearing retainer above the axle box seating, be provided with rolling bearing above the bearing retainer, the roller bearings quill shaft, it is characterized in that: between rolling bearing and quill shaft, be provided with inner ring, inner ring is enclosed within on the quill shaft, inboard, the axial two ends of inner ring has inclined hole, in inclined hole, be provided with the cover that tightens that matches with inclined hole, tighten and be enclosed within on the quill shaft, tighten the axial end of cover and be provided with to make to tighten and be enclosed within the inclined hole along the axially movable jackscrew of quill shaft outer side surface.Beneficial effect: the utility model is installed together rolling bearing and quill shaft by inner ring, has shortened the transformation cycle.

Description of drawings:

Fig. 1 is the structural representation of the patent No. 98244746.9 patents;

Fig. 2 is the structural representation of the utility model improvement part.

Embodiment: as shown in Figure 1, the structure of the patent No. 98244746.9 patents is that being provided with the top in the headstock is the axial seat 6 of bearing sphere shape, is provided with bearing retainer 5 above the axial seat 6, the top of bearing retainer is rolling bearing 4, rolling bearing 4 support hollow axles 3.Structure of the present utility model is the improvement of carrying out on the basis of aforementioned patent, Fig. 2 is the structural representation of improvement part, because symmetrical configuration, so this figure has only provided the partial schematic diagram of improvement part, as shown in Figure 2, between rolling bearing 4 and quill shaft 3, be provided with inner ring 2, inner ring is installed in the quill shaft neck, during enforcement, inner ring can be two-part, two-part inner ring is connected and fixed by the snap ring 7 of end, inner ring is enclosed within on the quill shaft, and inboard, the axial two ends of inner ring has inclined hole, is provided with tightening of matching with inclined hole and overlaps 1 in inclined hole, tighten cover and 1 be enclosed within on the quill shaft, tighten the axial end of cover and be provided with to make to tighten and be enclosed within the inclined hole along the axially movable jackscrew 8 of quill shaft outer side surface.Because jackscrew can make and tighten cover and 1 move axially, thereby change the radially amount of being full of between inner ring and the quill shaft in inclined hole, fix bearing, finish Mounting of Rolling Contact Bearing.

Claims
