Effect of Four Point Contact Slewing Bearing Groove Curvature Parameters on the Stress State

Abstract: Applying the finite element method, the function of finite element analysis software AnsysWorkbench is powerful. Analysis 30 groups of different groove curvature radius coefficient model in extreme condition, obtained in applying extreme working conditions, stress and deformation data. Analysis results show that the inner groove curvature coefficient is 0.525, the outer ring raceway curvature coefficient of bearing is 0.52 when the slewing bearing shows maximum carrying capacity. Calculation, results provide analysis basis for slewing bearing design.

Friction -wheel drive formula bogie carousel

Abstract: The utility model relates to a vehicle manufacture and maintenance of equipment technical field overhaul inconveniently and a friction -wheel drive formula bogie carousel that provide to current bogie carousel. Including the carousel body of steel construction, still hug closely the friction pulley of carousel setting, drive friction pulley pivoted friction pulley actuating mechanism, sticis the hold -down mechanism at carousel body side with the friction pulley including locating slewing bearing, the slewing bearing seat of locating the slewing bearing lower extreme that carousel body center below is used for supporting the carousel body, locating carousel body side, be equipped with the supporting wheel set spare of at least three support carousel body in carousel body below, the frictional wheel drive connect the output at friction pulley actuating mechanism. The utility model discloses because friction pulley and speed reducer are all adorned in the carousel outside, so maintain more conveniently, during the power failure, can loosen hold -down mechanism's lock nut and screw rod, rotate through the manpower drive carousel. This scheme simple structure, convenient operation, efficient, safe and reliable.

Device for storing and conveying coal in flat-bottom coal bunker

Abstract: The utility model belongs to the field of coal storage and transportation, and particularly relates to a device for storing and conveying coal in a flat-bottom coal bunker The device comprises the flat-bottom coal bunker, wherein a charge port and a discharge port are disposed on the flat-bottom coal bunker; the discharge port is located at the bottom centre of the flat-bottom coal bunker; a slewing bearing, a material-taking spiral and a circular guide rail taking the centre of the discharge port as a circular centre are disposed on the interior bottom of the flat-bottom coal bunker; the slewing bearing is located just above the discharge port; the material-taking spiral is driven by a spiral drive device; one end of the material-taking spiral is fixed on the slewing bearing via a fixing end, and the other end of the material-taking spiral is connected with a spiral slewing drive device; the spiral slewing drive device is installed on the circular guide rail and drives the material-taking spiral to perform a slewing motion by taking the centre of the discharge port as a circular centre; and a convey device is disposed just below the discharge port By utilizing the flat-bottom coal bunker as equipment for coal storage and transportation, the utilization rate of the bunker is greatly increased, and the construction cost of the bunker is greatly reduced; and the material-taking spiral can realize 360-degree full-range material taking in the bunker without generating the phenomenon of material blockage

A robot for giving slewing bearing fat liquoring evenly reduces waste

Abstract: The utility model discloses a robot for giving slewing bearing fat liquoring evenly reduces waste, including the bottom plate, the last skin weld of bottom plate has the riser, the downthehole bearing frame that is fixed with of mid -mounting of riser, the preceding side of bearing frame rotates and is connected with four -jaw chuck, four -jaw chuck's the outside is fixed with slewing bearing, this a robot for giving slewing bearing fat liquoring evenly reduces waste, comprising a base plate, it is fixed convenient, the suitability is strong, servo motor drives four -jaw chuck rotates to make and spouts the surface coating antirust oil of glassware to slewing bearing, the spraying is even, the oil outlet quantity of spouting the glassware can be adjusted, the slewing bearing who adapts to different diameters, convenient fixing, the motor driver has great applicability, send the oil incasement back to after straining, the waste of the unnecessary production of oil has been avoided

Powder metallurgy slewing bearing and preparation method thereof

Abstract: The invention discloses a powder metallurgy slewing bearing. The slewing bearing is characterized in that: the bearing is prepared from following raw materials in parts by weight: 0.8-1.2 of graphite, 1.6-1.8 of silicon, 1.1-1.3 of manganese, 2.6-2.8 of chromium, 11.7-12.1 of aluminum, 1.5-1.7 of molybdenum, 0.2-0.3 of chromium diboride, 0.4-0.5 of ZrO2, 0.3-0.5 of SiO2, 3.2-3.4 of microcrystalline wax, 0.2-0.3 of tungsten carbide, 0.2-0.4 of TiC, 92-94 of iron powder and 1-2 of an auxiliary agent; and the slewing bearing is advantageous in that a special raw material formula is adopted, so that the slewing bearing produced has high performance indexes, good glossiness, good stability, excellent structure toughness, excellent stiffness, excellent hardness, excellent antifatigue performance, excellent tensile strength, long service lifetime and wide application scope, and phenomena of fracture and the like are not prone to generation.
