Description
Technical Field
The utility model relates to a bearing technical field specifically is a bearing for diesel engine.
Background
At present, a main bearing in an engine cylinder body is commonly used as an integral bearing, a commonly used step hole and a check ring are limited, and the disassembly and maintenance are difficult.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome current defect, provide a bearing for diesel engine, simple structure, splittable dismantlement maintenance, spacing effect are better, can be used to the special bearing that the diesel engine cylinder was used, can effectively solve the problem in the background art.
In order to achieve the above object, the utility model provides a following technical scheme: the bearing for the diesel engine comprises a bearing outer ring, a bearing inner ring, a plurality of cylindrical rollers and a retainer, wherein the outer side of the bearing outer ring is provided with a limiting groove, the bearing inner ring is provided with a one-way limiting step, the retainer is used for fixing the cylindrical rollers, the cylindrical rollers are located in an annular groove between the bearing outer ring and the bearing inner ring, the retainer is located in the annular groove, and the retainer uniformly fixes the cylindrical rollers in the annular groove.
As an optimized technical scheme of the utility model, the no step end of bearing inner race is equipped with bearing inner race baffle.
Compared with the prior art, the beneficial effects of the utility model are that: the bearing for the diesel engine has the advantages of simple structure, detachable disassembly and maintenance and better limiting effect, and can be used for special bearings for diesel engine cylinders.
Drawings
Fig. 1 is a schematic view of an explosion structure of the bearing of the present invention;
fig. 2 is a schematic sectional view of the present invention.
In the figure: the bearing comprises a bearing outer ring 1, a bearing inner ring 2, a cylindrical roller 3, a retainer 4, a bearing inner ring baffle 5 and a limiting groove 6.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides a technical solution: a bearing for a diesel engine comprises a bearing outer ring 1 with a limiting groove 6 on the outer side, a bearing inner ring 2 with a unidirectional limiting step, a plurality of cylindrical rollers 3 and a retainer 4 for fixing the cylindrical rollers 3, wherein a limiting plate is arranged on the end surface of an outer machine body hole or at the step and clamped into the limiting groove 6 to limit the radial movement of the bearing, the cylindrical rollers 3 are positioned in an annular groove between the bearing outer ring 1 and the bearing inner ring 2, the cylindrical rollers 3 are used for the relative rotation movement between the bearing inner ring 2 and the bearing outer ring 1, the retainer 4 is positioned in the annular groove, the cylindrical rollers 3 are uniformly fixed in the annular groove by the retainer 4, the retainer 4 is used for being sleeved in and limiting the movement of the cylindrical rollers 3 to avoid the mutual contact and collision between the cylindrical rollers 3, the bearing inner ring 2 is provided with the unidirectional limiting step and can be integrally separated from the bearing after being sleeved with a shaft body, the bearing used for the diesel engine has the advantages of simple structure, detachable disassembly and maintenance and better limiting effect, and can be used for special bearings for diesel engine cylinder bodies.
When in use: the bearing outer ring 1 is connected with the cylindrical roller 3, the retainer 4 is pressed into an external bearing hole mounting hole, and an external mounting limiting plate is clamped into a limiting groove 6 of the bearing outer ring 1 and fixed to limit the axial operation of an excircle;
pressing the bearing inner ring 2 into the external crankshaft shaft diameter, wherein the step surface of the bearing inner ring 2 is contacted with the step of the shaft neck, and the crankshaft and the bearing inner ring 2 are assembled into a bearing to limit the movement to the bearing outer ring 1 and ensure the rotation of the crankshaft;
the bearing inner ring baffle 5 is sleeved at the installation position of the bearing outer part to the crankshaft and the bearing inner ring 2, so that the direct contact between the external installation part and the bearing inner ring 2 can be avoided;
the outer side of the outer bearing mounting hole is provided with an oil seal with the same outer diameter, so that the contact between the bearing and the inside of the machine body and the outside can be isolated;
when the interior of the machine body needs to be disassembled for maintenance, the crankshaft and the bearing inner ring 2 can be directly separated from the bearing part by hands, and the bearing can be separated from the hole or the shaft without other tools.
The utility model discloses simple structure, detachable dismantlement maintenance, spacing effect are better, can be used to the special bearing that the diesel engine cylinder body was used.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
