Detailed Description
The invention will now be described in further detail with reference to the accompanying drawings, which are simplified and are only schematic illustrations of the basic structure of the invention, and the embodiments thereof, and which therefore only show the constructions associated with the invention.
As shown in fig. 1, a three-dimensional structure diagram of a deep groove ball bearing with a sealing cover includes: the sealing lower cover 15, the sealing upper cover 7, and the bearing outer ring 1 and the bearing inner ring 4 which are arranged in the sealing lower cover 15;
the bearing outer ring 1 comprises a steel ball mounting hole 6 which radially penetrates through the bearing outer ring 1, and a closed plate socket 5 is arranged on the surface which is above the steel ball mounting hole 6 and is in contact with the sealing upper cover 7; the bearing inner race 4 is mounted in the inner race mounting plate 14 and both the bearing inner race 4 and the bearing outer race 1 are provided with an inner raceway. A plurality of steel balls 3 are arranged in the steel ball placing holes 16 of the steel ball retainer 2, and the steel balls are connected with the inner raceway in a sliding way.
As shown in fig. 2 and fig. 3, a partial structure diagram and a top view of a deep groove ball bearing with a sealing ring, the bearing of the device comprises a sealing upper cover 7 and a sealing lower cover 15, the sealing upper cover 7 comprises a second through hole 13, a plurality of bolt insertion holes 8 and a sealing ring 12 which are circumferentially arranged along the second through hole 13, the sealing upper cover 7 is further provided with a closing plate 9, a U-shaped groove 10 is arranged in the closing plate 9, and the length of the closing plate 9 is greater than the distance from a steel ball mounting hole 6 to a closing plate insertion hole 5; a second through hole 13 is also arranged in the inner ring mounting plate 14
The sealing lower cover 15 comprises an outer ring mounting plate 11, an inner ring mounting plate 14 and a steel ball retainer 2, wherein the steel ball retainer 2 is arranged between the inner ring mounting plate 14 and the outer ring mounting plate 11, and the inner ring mounting plate 14 is also provided with a first through hole 20;
as shown in fig. 4, a partial cross-sectional view of a deep groove ball bearing with a sealing ring, a steel ball retainer 2 comprises a plurality of locking arms 18, a plurality of fixing screw holes 17 and spring mounting grooves 21 are formed on the plurality of locking arms 18 at intervals, steel ball placing holes 16 are formed between the locking arms, and the size of the steel ball placing holes 16 is larger than the volume of steel balls 3; a plurality of lubricating oil channels 19 are arranged at the bottoms of the plurality of locking arms 18 in a penetrating manner, the plurality of lubricating oil channels 19 are connected with the plurality of steel ball placing holes 16, and the lubricating oil channels 19 are not in contact with the fixing screw holes 17; a spring 22 is installed in the spring installation groove 21.
In the utility model, after the closed plate blocks the steel ball mounting hole, the U-shaped groove can be connected with the inner raceway of the bearing outer ring, thereby preventing the inner raceway in the outer ring from being uneven, causing the steel ball to rub excessively to generate heat and generate noise, and affecting the operation effect of the whole bearing; because the closing plate is detachable joint, even can also change the closing plate after U type groove wearing and tearing, perhaps directly change the bearing inner race.
The lubricating oil channel has the advantages that the lubricating oil channel can move among the steel ball placing holes when lubricating oil is added, and the lubricating oil does not need to be added into each steel ball placing hole independently; and after the lubricating oil is added, part of the lubricating oil is stored in the oil duct, part of the oil in the steel ball placing hole is reduced due to inertia and other factors during operation, and part of the stored lubricating oil also slides out of the oil duct to perform oil compensation again.
When the utility model is used, the steel ball can be directly placed into the inner raceway by the design of the steel ball mounting hole without pressure assembly, thereby reducing the abrasion of extrusion to the steel ball and the inner and outer rings of the bearing, and parts can not be abraded due to the fact that the assembly angle is not right caused by uneven force in mechanical installation or manual installation; in the device, the inner ring, the outer ring, the sealing upper cover and the sealing lower cover are single components, so that the disassembly and the installation are both quick, the damaged parts are easy to replace, and the parts are connected in a nesting way, so that the structure tightness is improved; the whole body is arranged in the sealed upper cover and the sealed lower cover, so that dust can be prevented, and the lubricating oil can be prevented from losing; the setting of spring in the tight arm of locking can prevent to lead to the sealed upper cover to be difficult to the condition dismantled because of part oil dirt mixes, can make sealed upper cover convenient to detach through the elasticity of spring.
When the novel bearing is actually used, the inner ring and the outer ring of the bearing are respectively arranged on the inner ring mounting plate and the outer ring mounting plate of the sealing lower cover, and a small gap exists between the inner ring and the outer ring and the retainer because steel balls are not additionally arranged; then placing steel balls through the steel ball mounting holes, simultaneously rotating the sealing lower cover, aligning the steel ball placing holes with the steel ball mounting holes, placing the steel balls, and circulating the process until the steel balls are loaded; then inserting the closed plate into a closed plate socket of the bearing outer ring, wherein the sealing ring is positioned between the inner ring and the outer ring of the bearing, and finally installing a bolt into a screw hole through a bolt jack so as to install the sealed upper cover and the sealed lower cover together; because the inner diameter of the inner ring mounting plate is smaller than that of the bearing inner ring, the sealing cover cannot contact with a shaft to generate friction when the device works.
In light of the foregoing, it is to be understood that various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
