Abstract
The utility model belongs to technical field of bearings, relates in particular to a kind of cross-bearing for excavator.Operation of power excavators environment is poor, and working load is high, and muddy water, sandstone easily enter Bearing inner in operation process, and bearing is fragile, need to often change, each side high cost.The utility model cross-bearing includes outer ring, inner ring, roller and sealing ring, the roller of cylinder is provided between outer ring and inner ring, roller is fixed by the dress ball pin on outer ring and the alignment pin through outer ring and dress ball pin, and alignment pin is pyramidal structure, is matched with outer ring and dress ball pin；Roller outer end is sealed with sealing ring.The utility model simple structure, assembling is simple, by the way of cylindrical roller replaces steel ball, improves the bearing capacity of bearing, it is ensured that excavator speed when work is more smooth, and anti-mud, water resistance are splendid, substantially increase service life.
Description
Technical field
The utility model is related to technical field of bearings, relates in particular to a kind of cross-bearing for excavator.
Background technology
Operation of power excavators environment is poor, and working load is high, and muddy water, sandstone easily enter Bearing inner, bearing in operation process
It is fragile, need to often change, each side high cost.
Utility model content
Deficiency of the purpose of this utility model aiming at prior art, there is provided a kind of good seal performance and withstand forces it is big
Cross-bearing.
The utility model is adopted the following technical scheme that：
A kind of cross-bearing, including outer ring, inner ring, roller and sealing ring, cylinder is provided between described outer ring and inner ring
Roller, described roller is fixed by the dress ball pin on outer ring and the alignment pin through outer ring and dress ball pin, and described determines
Position pin is pyramidal structure, is matched with outer ring and dress ball pin；Described roller outer end is sealed with sealing ring.
Used as further improving and supplementing to such scheme, the utility model also includes following additional technical feature：
Described sealing ring is formed by skeleton and rubber seal two parts bonding of metal, good seal performance, and grease is not
Can overflow.
Described bearing is additionally provided with the steady pin that screw thread is screwed in dress ball pin, alignment pin is fixed, it is ensured that bearing
Fastening.
Multiple screwed holes are equipped with the end face of the outer ring, are installed and is pulled down conveniently.
The inner ring is respectively equipped with hole on end face and periphery, installs and positioning is convenient.
Following beneficial effect can be reached using the utility model：Its simple structure, assembling is simple, using cylindrical roller generation
For the mode of steel ball, the bearing capacity of bearing is improve, it is ensured that excavator speed when work is more smooth, and anti-mud,
Water resistance is splendid, substantially increases service life.
