The purpose of this utility model is achieved like this: a kind of ship unloaders contact wire roller formula pivoting supports with 3, comprise the outer ring, inner ring, steel ball and spacing block, on the inwall of outer ring, offer the semicircle cambered surface the annular in raceway, raceway outside the corresponding annular of offering the semicircle cambered surface on the excircle of inner ring, raceway and the outer raceway of annular are combined into the raceway of steel ball in this annular, steel ball and spacing block are installed in this raceway successively, offer closure gasket groove respectively in the upper end portion of outer ring inwall with in the underpart of interior ring outer wall, in each closure gasket groove, Stamping Steel Ribbon is installed, it is characterized in that: is that benchmark is divided into the last outer ring of being with step hole and the following outer ring of step type with the outer ring by the horizontal center line of raceway, in the step hole of last outer ring, offer interior threaded hole, and corresponding external thread section is made on the top that will descend the outer ring, advance to go up the corresponding spinning in the top of following outer ring in the outer ring, corresponding to last, the horizontal integration portion of following outer ring between the two, circumference uniform distribution on the base ring face of following outer ring offer through on the countersunk head screw of outer ring, spinning bolt in each countersunk head screw and connecting makes things convenient for the mounting or dismounting of steel ball and separation sleeve; Level (radially) center line with raceway is a benchmark, on the outer raceway of inner ring, offer arc groove in the annular, setting-in steel wire and form steel traveler in the arc groove in this annular, and the part that makes steel wire exposes to arc groove in the annular, and on this local steel wire that exposes, offer the secondary raceway of annular circular arc, simultaneously, on the interior raceway of outer ring the symmetry offer twice be mutually 120 ° of angles on, arc groove in the following annular, on this, equal setting-in steel wire and form steel traveler in the arc groove in the following annular, and the local evagination that makes steel wire arc groove in annular, and on the male part of this steel wire, all offer the secondary raceway of annular circular arc, three road steel traveler form the main raceway of steel ball, rolling element: steel ball with in, raceway on the outer ring is directly contact, but by and be embedded in rolling between three steel wires in the raceway realizes, relatively rotating between the outer ring; In addition, offer the oil duct that communicates with raceway and priming cup is installed on the base ring face of following outer ring, circumference uniform distribution is offered axial mounting hole respectively on inside and outside circle, and with the support corresponding connection of high-strength bolt with ship unloaders, whole pivoting support is vertically installed respectively.
Because rolling element: steel ball does not directly contact with raceway on the outer ring with inner ring, so just reduced the difficulty of the raceway processing technology of inside and outside circle, the geometric accuracy that has kept inside and outside circle, and load is evenly distributed on each rolling element, bearing capacity is even, lubricated simultaneously more convenient, thus make pivoting support realize low friction, low noise, low temperature rise, high rotating speed.
The ship unloaders that the utility model proposed contact wire roller formula pivoting supports with 3, and rational in infrastructure, easy to use and reliable, bearing capacity is even, and are lubricated convenient, and pivoting support is realized low friction, low noise, hanged down temperature rise, high rotating speed.
Now in conjunction with the accompanying drawings and embodiments the ship unloaders that the utility model proposed are described further with 3 contact wire roller formula pivoting supports.
Description of drawings
Fig. 1 is the main cross-sectional schematic of the ship unloaders that propose of the utility model with 3 contact wire roller formula pivoting supports.
