Slewing bearing mills tooth cooling system

Abstract: Slewing bearing mills tooth cooling system includes through connections's air supply device, dehumidifier, air-fuel mixture device and jet-propelled pipe in proper order, and does the oil tank of air-fuel mixture device fuel feeding, the air-fuel mixture device includes the hybrid tube, and the hybrid tube is middle thin and structure that enlarge to both ends from top to bottom gradually, is provided with the air-supply line that extends to hybrid tube inside in the top center of hybrid tube, be provided with on the lateral wall of hybrid tube upper end with said oil tank intercommunication advance oil pipe, be provided with flow control valve on advancing oil pipe, the lower extreme of hybrid tube is connected with a plurality of jet-propelled pipes, spouts tracheal end fixing down near the milling cutter of milling machine upright. The utility model discloses a ventilated mode, it is pollution-free, saved and carried out the trouble handled to the cutting fluid, in the wind that blows off, increased a small amount of atomizing oil, play lubrication action, air-fuel mixture device simple structure, convenient to use.

Crane and slewing bearing structure thereof

Abstract: The invention discloses a slewing bearing structure of a crane The structure comprises a support case, an inner cylinder, an outer cylinder, mounting plates and a cover plate The end face of the support case is a connection board, and the bottom of the support case is a base plate One end of the inner cylinder is welded with the base plate, and the other end of the inner cylinder is welded with the cover plate One end of the outer cylinder is welded with the connection board, and the other end of the outer cylinder is welded with the cover plate The mounting plates are symmetrically arranged in the support case, and the distance from the mounting plates to the inner cylinder is greater than the distance from the outer cylinder to the inner cylinder As the distance from the mounting plates to the inner cylinder is greater than the distance from the outer cylinder to the inner cylinder, when the mounting plates and the inner cylinder are welded on the base plate of the support case, the welding deformation is reduced obviously When the slewing bearing structure is applied with force, as the distance between the mounting plates and the inner cylinder is large, the base plate uniformly disperses the applied pressure, thereby realizing more reasonable bearing on the base plate The invention also discloses a crane installed with the above slewing bearing structure

Slewing bearing overturning mechanism

Abstract: The invention relates to the technical field of machinery, in particular to a slewing bearing overturning mechanism. The slewing bearing overturning mechanism comprises two ground rails and a travelling trolley, wherein the two ground rails are parallel to each other; the travelling trolley is arranged between the two ground rails and above the two ground rails; a gantry bracket is arranged on thetwo ground rails; a pair of opposite guiding rail sliders is arranged on the side wall of the gantry bracket; a connecting assembly is arranged on the guiding rail sliders; a rotating motor and a third speed reducer are arranged behind the connecting assembly; a rotating device is arranged in front of the connecting assembly; an output shaft of the rotating motor is coaxially connected with an input shaft of the third reducer; and an output shaft of the third reducer is fixedly connected to the rear end of the rotating device through the connecting assembly. By using the slewing bearing overturning mechanism, the inner ring, the outer ring and assemblies of a slewing bearing are automatically overturned to facilitate the machining and assembling of the slewing bearing. The slewing bearingoverturning mechanism has the advantages that the structure is compact, the assembling is convenient, the occupation of a crane is avoided, the safety of workers is ensured, and the overturning efficiency is improved.

Slewing bearing test bench

Abstract: The utility model discloses a slewing bearing test bench belongs to slewing bearing inspection test bench technical field. The utility model discloses in, be equipped with initiative slewing bearing at the upper surface of base, initiative slewing bearing's inner circle and base fixed connection, and initiative slewing bearing links to each other with actuating mechanism, and this actuating mechanism drives initiative slewing bearing and is rotary motion, be equipped with the cab apron in initiative slewing bearing's top, initiative slewing bearing's outer ring gear and the lower fixed surface who crosses the cab apron are connected, and the slewing bearing's that awaits measuring inner circle and the last fixed surface who crosses the cab apron are connected. The utility model discloses in be rotary motion through actuating mechanism drive initiative slewing bearing to driving the inner circle of being surveyed slewing bearing and rotating, and apply different load to it through loading device, the performance parameter when bearing different load with simulation tests slewing bearing under the normal service condition changes, and the test result is accurate, the slewing bearing's that can guarantee to await measuring safety and reliability service.
