Description
Technical field
This utility model relates to a kind of grinder mounting structure of intermediate shaft.
Background technology
Existing grinder, its gear-box is internally provided with more travelling gear, it is necessary to ensure stable transmission effect, it is to avoid because power transmission shaft polarizes under high-speed rotation, cause under long time running, and parts wear is serious, is substantially reduced the service life of equipment.But, the intermediate propeller shaft of existing grinder gear-box, is often each sheathed bearing at the two ends of axle, and under running up, axle often polarizes away from the other end of power intake, causes equipment operation unstable.
Utility model content
This utility model makes improvement for above-mentioned prior art Problems existing, and namely technical problem to be solved in the utility model is to provide a kind of grinder mounting structure of intermediate shaft, it is ensured that jackshaft operating is stable, improves service life.
In order to solve above-mentioned technical problem, the technical solution of the utility model is: a kind of grinder mounting structure of intermediate shaft, including a multidiameter, described multidiameter bottom is provided with the annular table terrace that two external diameters are sequentially reduced to outer end from centre, described multidiameter upper end is provided with the external diameter annular table terrace less than middle part external diameter, three step surfaces of described multidiameter are mounted on bearing, two bearings of its outermost end are deep groove ball bearing, its lower end part bearing on inner step surface is taper roll bearing, in the middle part of described multidiameter, sidewall is provided with gear, described multidiameter upper end is provided with for transmitting, with driving mechanism, the keyway being connected.
Further, described multidiameter two ends are provided with the flange being enclosed within bearing.
Further, described gear is helical gear, described gear and multidiameter integral production or be fabricated separately.
Compared with prior art, this utility model has the advantages that this device by arranging two bearings in the bottom of a multidiameter, it is ensured that this axle under running up for a long time, stability of rotation, extension device service life.
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Accompanying drawing explanation
Fig. 1 is the state diagram that this utility model embodiment uses.
Fig. 2 is the explosive view of this utility model embodiment.
In figure: 1-gear-box, 2-multidiameter, 21-gear, 3-taper roll bearing, the deep groove ball bearing of 4-lower end, the deep groove ball bearing of 5-upper end, 6-flange.
Detailed description of the invention
Embodiment one: as shown in Figure 1 and 2, a kind of grinder mounting structure of intermediate shaft, including a multidiameter 2, described multidiameter 2 bottom is provided with the annular table terrace that two external diameters are sequentially reduced to outer end from centre, described multidiameter upper end is provided with the external diameter annular table terrace less than middle part external diameter, three step surfaces of described multidiameter are mounted on bearing, its bearing topmost is deep groove ball bearing 5, the bearing of its bottom is also deep groove ball bearing 4, its lower end part bearing on inner step surface is taper roll bearing 3, sidewall is provided with in the middle part of described multidiameter gear 21, described multidiameter upper end is provided with for transmitting, with driving mechanism, the keyway being connected.
In the present embodiment, described multidiameter two ends are provided with the flange 6 being enclosed within bearing.
In the present embodiment, described gear 21 is helical gear, described gear 21 and multidiameter 2 integral production.
As shown in Figure 1, this multidiameter is arranged on the middle part of gear-box 1, need to drive multiple pinion rotation, when running up, the deep groove ball bearing at multidiameter two ends is for bearing the radial force of axle, the taper roll bearing 3 of inner side, bottom time is for bearing the axial force of axle, by the combined effect of bearing, it is ensured that multidiameter stablizing under high-speed rotation.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to this utility model claim change and modify, and all should belong to covering scope of the present utility model.
