Embodiment Construction

[0021] The structural form of the drum tooth slewing bearing of the present invention is the same as the general slewing bearing structure, and is composed of an outer ring, an oil cup, an upper seal, a rolling body, a spacer block, an inner ring, an upper seal, a plug and a tapered pin.

[0022] Such as figure 1 with Figure 4 As shown, the teeth are straight teeth and drum-shaped external tooth slewing bearings. The difference between the two is that the tooth profile of the external tooth slewing bearings with straight teeth is a straight line. (Such as image 3 shown), the profile of the 1-axis cross-section of the addendum circle is also a straight line; the tooth part is an external gear slewing bearing with drum-shaped teeth, and the indexing circle cut off on the 6-axis section of the addendum circle is an arc. It is called the displacement circle 5, the displacement circle is spherical, and the tooth profile of the cutting section of the indexing circle is drum-shap...

Abstract

The invention discloses a crowned teeth slewing bearing which consists of an outer ring, an oil cup, an upper seal, a rolling body, an isolation block, an inner ring, an upper seal, a plug and tapered pin, and is characterized in that the teeth parts are all crowned teeth, a reference circle line excised from the axial section of the teeth parts is a section of arc, the circle is a displacement circle, the displacement circle is spherical, and the tooth profile of the excised section of the reference circle is in a waist drum shape. The slewing bearing structure is novel, the bearing capacity is strong, and the phenomenon of teeth breaking in use of the slewing bearing is reduced.

Description

technical field [0001] The invention belongs to a new type of slewing bearing, in particular to a drum-shaped tooth slewing bearing. Background technique [0002] At present, the teeth of most slewing bearing ring gears are either straight teeth or bevel teeth, and there is no slewing bearing whose teeth are drum-shaped teeth. Contents of the invention [0003] The object of the present invention is to provide a slewing bearing whose ring gear teeth are drum-shaped teeth. The slewing bearing has a novel structure, strong bearing capacity, and reduces tooth breakage during the use of the slewing bearing. [0004] The object of the present invention is achieved in this way: the drum-shaped tooth slewing bearing is composed of an outer ring, an oil cup, an upper seal, a rolling element, a spacer block, an inner ring, an upper seal, a plug and a tapered pin, and its characteristic is that the The teeth of the slewing bearing are all drum-shaped teeth, and the indexing circle...
