Description
Technical Field
The utility model relates to a bearing technical field, specifically speaking relate to a footstep bearing for rotation axis bottom.
Background
For some vertically arranged rotating shafts, bearings are required to be arranged on two sides of the rotating shaft, and particularly for the bearing at the bottom of the rotating shaft, the bearings not only bear the gravity load of the rotating shaft, but also prevent the rotating shaft from sinking and dislocating.
Disclosure of Invention
An object of the utility model is to solve above-mentioned problem, provide a footstep bearing for rotation axis bottom, it is applicable to lifting the rotation axis bottom.
In order to solve the above problem, the utility model discloses a technical scheme as follows:
a footstep bearing for rotation axis bottom, its characterized in that, including bearing frame, outer rotating sleeve, interconnection axle sleeve, the bearing frame has cyclic annular upper edge, and the bearing frame inboard is equipped with the round swiveling wheel, and outer rotating sleeve is located along the inboard, and outer rotating sleeve is located to the interconnection axle sleeve inboard, and the interconnection axle sleeve is equipped with the collet that holds outer rotating sleeve bottom, and the collet bottom is equipped with the bracing piece, and the bracing piece passes through the fix with screw with collet, outer rotating sleeve, and the bracing piece radially sets up on the swiveling wheel.
Furthermore, the outer side of the outer rotating sleeve is provided with a side wheel which is arranged at the top of the upper edge.
Furthermore, the outer rotating sleeve and the bottom support are provided with through oil injection channels.
Compared with the prior art, the utility model has the beneficial characteristics that:
the utility model discloses a rotation axis passes through the interconnection axle sleeve and drives outer rotating sleeve and rotate, and the bracing piece plays the support, lifts the effect to rotation axis, interconnection axle sleeve, outer rotating sleeve, and the bracing piece has reduced the area of contact of collet with the swiveling wheel simultaneously, has reduced the frictional resistance among the rotation process, and the bracing piece drives the rotatory in-process of collet, and the swiveling wheel rotation has reduced the wearing and tearing of bracing piece to the bearing frame.
The bearing seat, the rotating wheel, the bottom support and the support rod play roles in positioning and lifting the inner connecting shaft sleeve and the outer rotating sleeve, bear the gravity load of the rotating shaft and prevent the rotating shaft from sinking and dislocating.
