Description of the embodiments
The square bearing convenient to connect as shown in fig. 1-2 comprises a bearing outer ring 1 and a bearing inner ring 2, and rolling bodies 3 are arranged between the bearing outer ring 1 and the bearing inner ring 2 in a surrounding manner. The periphery of the bearing outer ring 1 is square, a circular groove is formed in the upper side of the bearing outer ring 1, and the bearing inner ring 2 and the rolling bodies 3 are arranged in the circular groove. The inner periphery of the bearing outer ring 1 (namely the inner wall of the circular groove) and the outer periphery of the bearing inner ring 2 are C-shaped with opposite openings, so that the rolling bodies 3 can be conveniently limited. The rolling bodies 3 can be separated from each other through a retainer (not shown), so that the rolling bodies 3 are prevented from biting each other, and in some application occasions with lower rotating speeds, the rolling bodies 3 can be directly fully distributed to form a full-bead bearing, so that the structure is further simplified, the installation is convenient, and the rolling bodies are not described in the prior art. The center of the bearing inner ring 2 is provided with a square mounting hole 4. To form a fit therewith, the end of the connecting shaft is machined to form a square shape for fitting therewith.
The bearing outer ring 1 is provided with a bearing fixing screw hole. The bearing fixing screw hole comprises a first bearing fixing screw hole 5 arranged at the bottom of the bearing outer ring 1 and a second bearing fixing screw hole 6 arranged at the periphery of the bearing outer ring 1, so that the bearing is conveniently installed in an embedded mode on equipment, and is screwed in from the outer side of the equipment through bolts and is connected with the bearing, and convenience and reliability of connection are guaranteed. Specifically, in the present embodiment, the number of the first bearing fixing screw holes 5 is at least 2, the second bearing fixing screw holes 6 are provided on four sides of the bearing outer race 1, and each side is not less than 2, ensuring connection reliability.
For further convenient connection, the four corners of the bearing outer ring 1 are provided with penetrating screw holes 7, so that the bearing can be directly screwed in from the upper side of the bearing outer ring 1 through long bolts to realize the installation of the bearing on equipment, and the connection efficiency and connection reliability are further improved.
The contact surface of the bearing inner ring 2 and the bearing outer ring 1 is annularly distributed with oil grooves 8, so that the friction of the contact surface in the rotation process is reduced.
The square bearing convenient to connect of this embodiment has simplified bearing structure, and bearing inner race 1 has the function of bearing frame concurrently, conveniently adopts embedded installation on equipment, has practiced thrift the space, and the axle adopts square grafting cooperation with the link of bearing simultaneously, for circular, has better restriction locate function, has further simplified the connection.
The utility model is not limited to the above embodiments, and based on the technical solution disclosed in the utility model, a person skilled in the art may make some substitutions and modifications to some technical features thereof without creative effort according to the technical content disclosed, and all the substitutions and modifications are within the protection scope of the utility model.
