Breeding method for beef cattle

Abstract: The invention discloses a breeding method for beef cattle. A fermentation liquid is prepared from 50g of a fermenting agent, 1kg of corn flour and 50kg of water, when the fermentation liquid is prepared, the fermenting agent, the corn flour and the water are mixed, and the mixed material is placed for one hour before being used; mixing of the fermenting agent, the corn flour and the water is performed by using a pneumatic motor, the pneumatic motor includes a roller body, a slewing bearing, a slewing bearing platform, and a ring-shaped sieve plate device, the slewing bearing platform is provided with a rustproof hole used for placing the slewing bearing, and the slewing bearing is in hoop connection with the roller body and is filled into the rustproof hole from one end of the rustproof hole. The method provided by the invention avoids the problem that particle impurities rush into the rustproof hole and the slewing bearing, so that the slewing bearing is destroyed in the prior art.

Slewing bearing for environmental protection equipment

Abstract: The utility model discloses a slewing bearing for environmental protection equipment, which comprises an inner ring and an outer ring. A rolling groove on the outer wall of the inner ring is matched with a rolling groove on the inner wall of the outer ring to form a rail; steel balls and isolation blocks are filled in the rail; a transverse plug arranged on the outer ring is fixed onto the outer ring by the aid of a pin; an oil nozzle is arranged on the outer ring; and an upper sealing strip and a lower sealing strip are respectively embedded into the space between the rolling groove on the outer wall of the inner ring and the rolling groove on the inner wall of the outer ring. The sealing strips of the slewing bearing are not easy to deform, dustproof effect is fine, and the service life of the slewing bearing is prolonged.

Multifunctional assembling table for slewing bearing

Abstract: The invention provides a multifunctional assembling table for a slewing bearing, belongs to the technical field of machine manufacturing and assembling, and is applied to assembling of slewing bearingmanufacturing. The assembling table comprises a motor base, a driving motor, a rotary shaft, a rotary arm, a connecting head, a hollow shaft, a stepping motor, a transmission shaft, a first lead screw, a first slide block, a bearing pedestal assembly, a first bevel gear, a primary bevel gear, a second lead screw, a second slide block, a second bevel gear, a third lead screw, a third slide block,a third bevel gear, a first gear, a second gear, a base, a storage rack and a nylon supporting bar. The working principle of the multifunctional assembling table for the slewing bearing is as follows:when the stepping motor rotates, power is successively transferred to the transmission shaft, the first gear, the second gear, the hollow shaft, the primary bevel gear, three bevel bears and three lead screws through a coupling so as to achieve synchronous radial movement of the three slide blocks, so that a quick centering and positioning function of an outer ring or an inner ring is achieved; when the driving motor rotates, power is transferred to the rotary shaft, the rotary arm and the connecting head through the coupling to drive the outer ring or the inner ring of the slewing bearing torotate at a certain angle, so that the indexing function in the assembling process of the slewing bearing is achieved.

Crane and slewing mechanism thereof

Abstract: The invention discloses a crane and a slewing mechanism thereof The slewing mechanism is used for the crane and comprises a slewing bearing gear, a slewing driving gear and a slewing power source, wherein the slewing driving gear is mounted on an output shaft of the slewing power source and engaged with the slewing bearing gear, and drives the slewing bearing gear to slew; the slewing bearing gear is herringbone; and the slewing driving gear is herringbone According to the crane and the slewing mechanism, the herringbone gears serve as an engagement mode of the slewing mechanism, the coincidence degree of the gears in an engagement process is increased, load-carrying capabilities of the gears are optimized, a slewing structure can be more compact under the same load condition, and structures of the herringbone gears offset axial forces generated when single bevel gears are used for transmission, thereby reducing harmful axial friction

Novel plug of slewing bearing

Abstract: The utility model relates to a novel plug of a slewing bearing, which belongs to a slewing bearing. The novel plug is characterized in that: the plug is in a cylindrical shape, and the right end of the plug is provided with an inwardly concave arc surface with the same radius as a steel ball; the left end of the plug is provided with an upwardly arranged rectangular positioning plate, and the right side surface of the positioning plate is an arc surface jointed with an outer circumferential surface of an outer ring; and radial countersunk head through holes are arranged on the positioning plate. When the novel plug is installed, threaded blind holes are respectively arranged on the outer circumferential surface of the outer ring of the slewing bearing corresponding to the countersunk head through holes, and connecting bolts are installed in the positioning plate, and are screwed into the threaded blind holes, so that the plug is fixed on the outer ring. The novel plug is convenient to assemble and easy to process, the radial size of the slewing bearing can be effectively reduced, and the application fields of the slewing bearing are further expanded.
