Background

The vertical mill is the first choice equipment of bulk material powder technology, and in the powder technology, the vertical mill has complicated and changeable working condition stress aiming at the requirements of different material physical properties, different material moisture and different product fineness. The vertical mill belongs to large-scale powder equipment, the annual operating rate of the vertical mill is more than or equal to 80 percent, and the vertical mill is required to have high reliability and stability in operation. The working condition characteristics of the vertical mill require that the design of the whole vertical mill and the details of each component are provided with specific requirements to meet the use of the vertical mill in different environments.

The vertical mill rocker bearing block is an important part for grinding materials during the operation of a vertical mill, and the stress is complex and variable. The existing vertical mill rocker arm bearing seat is derived based on a standard bearing seat or a standard bearing seat. The vertical mill has complicated working conditions and large impact force, so that the bearing seat of the rocker arm of the vertical mill has large stress change and is stressed in a multidirectional alternating manner. Standard bearing seats or standard bearing seat derivatives: due to the structural limitation, two sets of bearings of one set of grinding roller device can only bear axial force by a single set of bearing, so that the grinding roller rocker arm is easy to move laterally; the outer diameter clearance of the bearing is enlarged due to the strength limitation, and the bearing runs out of the outer ring.

Disclosure of Invention

The utility model aims at the defect that above-mentioned prior art exists, provide a novel grind rocking arm bearing frame structure immediately, its bearing frame size is stable solves the bearing and easily runs the outer lane problem, and the difficult emergence side of grinding roller rocking arm is moved, has prolonged the life of bearing.

The utility model discloses a realize that the technical scheme that above-mentioned purpose adopted is: the utility model provides a novel upright mill rocking arm bearing frame structure, including connecting two sets of bearing device on one set of grinding roller device, every set of bearing device includes the bearing, the bearing frame upper cover, the bearing frame base, the position sleeve, the gland, the location end cover, the bearing sets up between bearing frame base and bearing frame upper cover, the position sleeve is connected with the medial extremity face of bearing, the inboard gland cover of bearing overlaps outside the position sleeve and through screw respectively with bearing frame base and bearing frame upper cover fixed connection, the location end cover is connected with the outside terminal surface of bearing, the gland cover in the bearing outside overlaps outside the position end cover and through screw respectively with bearing frame base and bearing frame upper cover fixed connection, two sets of bearing device's bearing inner race all fixed restriction is on grinding roller device's rocking arm shafting, and two sets of bearing device's bearing outer lane fixed restriction respectively is on grinding roller device's two sets of bearing frame bases.

The utility model discloses a further technical scheme is: the two sets of bearing devices have the same and interchangeable gland structures at the two ends, and the glands are made of high-strength materials.

The utility model discloses grind rocking arm bearing frame structure immediately has following beneficial effect: one set of grinding roller device adopts two sets of bearing devices, and the two sets of bearing devices bear axial force simultaneously so that the grinding roller rocker arm is not easy to laterally move; the bearing seat is stable in size, the problem that the bearing is easy to run out of an outer ring is solved, and the service life of the bearing is prolonged; the bearing seat has the advantages that the pressing covers at the two ends of the bearing seat can be interchanged, the pressing covers at the two ends adopt high-strength structures, the connection strength of the bearing seat upper cover and the bearing seat base is increased after the pressing covers, the bearing seat upper cover and the bearing seat base are assembled, the problem that an outer ring of a bearing is easy to run is solved due to the stable size of the bearing seat, and the service life of the bearing is prolonged.

The structure of the rocker bearing block of the present invention will be further described with reference to the accompanying drawings and examples.

Drawings

FIG. 1 is a schematic structural view of the rocker bearing block structure of the vertical mill of the present invention;

the reference numbers illustrate: 1-positioning end cover, 2-gland, 3-bearing seat base, 4-bearing, 5-positioning sleeve, 6-sealing filler, 7-bearing seat upper cover, 8-rocker shaft system and 9-screw.

Detailed Description

As shown in FIG. 1, the present invention relates to a vertical mill rocker bearing structure, which comprises two sets of bearing devices connected to a set of grinding roller device. Each set of bearing device comprises a bearing, a bearing seat upper cover, a bearing seat base, a positioning sleeve, a pressing cover and a positioning end cover. The bearing is arranged between the bearing seat base and the bearing seat upper cover. The positioning sleeve is connected with the end face of the inner side of the bearing, the gland bush on the inner side of the bearing is sleeved outside the positioning sleeve and is respectively and fixedly connected with the bearing seat base and the bearing seat upper cover through screws, and sealing filler is arranged between the surface of the inner side of the radial gland and the outer side of the positioning sleeve. The positioning end cover is connected with the outer end face of the bearing. The gland on the outer side of the bearing is sleeved outside the positioning end cover and is respectively and fixedly connected with the bearing seat base and the bearing seat upper cover through screws, and sealing packing is arranged between the inner side surface of the radial gland and the outer side of the positioning end cover. The inner rings of the two sets of bearing devices are all fixedly limited on a rocker shaft system of the grinding roller device, the outer rings of the two sets of bearing devices are respectively fixedly limited on two sets of bearing seat bases of the grinding roller device, and the bearing seat bases of the grinding roller device are the bearing seat bases of the bearing devices.

The bearings of the two bearing devices on one grinding roller device bear the axial force of the grinding roller device simultaneously, so that the rocker arm of the grinding roller does not move laterally. The gland structures at the two ends of the two sets of bearing devices are the same and interchangeable, the gland is made of high-strength materials, the connection strength of the bearing seat upper cover and the bearing seat base is increased after the gland and the bearing seat upper cover are assembled with the bearing seat base, and the problem that the outer ring of the bearing is easy to run is solved due to the stable size of the bearing seat.

The above embodiments are only preferred embodiments of the present invention, the structure of the present invention is not limited to the forms illustrated in the above embodiments, and any modifications, equivalent substitutions and the like made within the spirit and principle of the present invention should be included within the scope of the present invention.
