The purpose of the utility model is achieved in that a kind of double L-shaped decussation roller formula pivoting support; Form by outer ring, lubricating cup, upward sealing, roller, inner ring, upward sealing, obstruction and taper pin; In the raceway of roller cross arrangement between outer ring and inner ring; It is characterized in that: its outer ring is L shaped ring, and the top of outer ring is the disk ring body, and the bottom is the cylinder ring body; Side at the cylinder ring body of outer ring is laterally offered plugging hole, and the diameter of this plugging hole is greater than the roller diameter, and the cylindrical obstruction of setting-in in plugging hole guarantees the sealing of raceway; Offer coaxial circular cone through hole in the outer ring with above stopping up on the Vertical direction, install taper pin and be used for locating obstruction; Offer raceway in the right-angle plane circular arc simultaneously on the inner peripheral surface in the middle part of the cylinder ring body of outer ring with on the side end face of stopping up; The opposite side of the cylinder ring body of outer ring laterally offer with semi-circle in the tapped hole oil duct that communicates of raceway, on this oil duct, lubricating cup is installed; At equipped inner ring of the interior week of the cylinder ring body of outer ring, inner ring also is L shaped ring, and the bottom of inner ring is the disk ring body, and top is the cylinder ring body, on the outer ring surface of inner ring, offer with the outer ring semi-circle in raceway with raceway outside the semi-circle of radius.
When outer ring and inner ring cooperate install after, raceway is square raceway with outer two the semi-circle raceways of raceway of right angle semi-circle with regard to forming a complete hatching in the right angle semi-circle, the section of outer ring and inner ring the same side just form one suitable put one inverted pair L shaped; In addition, offer annular groove,, prevent that the rainwater dust from getting into raceway so that Stamping Steel Ribbon to be installed in the upper edge hole position and the oral area position, inner ring cylinder ring body lower edge of the cylinder ring body of outer ring; During installation, with outer ring and the corresponding suit of inner ring, the roller of from plugging hole, in raceway, packing into successively, roller one horizontal one perpendicular cross arrangement finishes up to filling, with blocking plugging hole, taper pin is installed is then located obstruction.
Between two adjacent rollers, also can be equipped with spacing block,
The opposite side end face and the outer ring outer ring surface that stop up are complementary.
Double L-shaped pivoting support is installed and used in the process, and pivoting support connects with main frame through bolt, and bolt head is placed in the L type, has practiced thrift installing space; Can bear certain axial force, radial force and tilting moment are easy to installation and removal.
Combine accompanying drawing and embodiment that the double L-shaped decussation roller formula pivoting support that the utility model proposed is described further at present.
Description of drawings
Fig. 1 is the main cross-sectional schematic of the double L-shaped decussation roller formula pivoting support that proposes of the utility model.
Wherein: 1, outer ring, 2, lubricating cup, 3, go up Stamping Steel Ribbon, 4, roller, 5, inner ring, 6, the lower seal bar, 7, stop up, 8, taper pin.
Embodiment
As can be seen from Figure 1: a kind of double L-shaped decussation roller formula pivoting support, comprise a kind of double L-shaped decussation roller formula pivoting support, by outer ring 1, lubricating cup 2, on seal 3, roller 4, inner ring 5, on seal 6, stop up 7 and taper pin 8 form.Roller 4 is uniformly distributed with in the raceway that is arranged between outer ring 1 and the inner ring 5, stops up 7 and is installed in the plugging hole preventing that roller 4 from coming off, and raceway is played seal action.Outer ring 1 is L shaped ring, and the top of outer ring 1 is the disk ring body, and the bottom is the cylinder ring body, circumference uniform distribution mounting holes on the disk ring body of outer ring 1; One side of 1 cylinder ring body is laterally offered plugging hole in the outer ring, and the diameter of this plugging hole is greater than the roller diameter, the cylindrical obstruction 7 of setting-in in plugging hole; Vertically offer coaxial circular cone through hole in outer ring 1 with stopping up on 7, in this circular cone through hole, install taper pin 8 and stop up 7 with the location.Offer raceway in the right-angle plane circular arc (diagonal is positioned at horizontal plane) simultaneously on the inner peripheral surface in the middle part of the cylinder ring body of outer ring 1 and on the left end face of obstruction 7, and on its right end face of obstruction 7, offer the cambered surface that is complementary with outer ring 1 outer ring surface; The opposite side of the cylinder ring body of outer ring 1 laterally offer with semi-circle in the tapped hole oil duct that communicates of raceway, lubricating cup 2 is installed on this oil duct, keep the lubricated of raceway with oiling; The interior week of 1 cylinder ring body is equipped with inner ring 5 in the outer ring; Inner ring 5 also is L shaped ring; The bottom of inner ring 5 is the disk ring body; Top is the cylinder ring body, on the outer ring surface of inner ring 5, offer with the outer ring semi-circle in raceway with raceway outside the semi-circle of radius, circumference uniform distribution mounting holes on the disk ring body of inner ring 5 bottoms; Like this, behind outer ring 1 and inner ring 5 suits, raceway just forms a complete square raceway with outer two the semi-circle raceways of raceway of right angle semi-circle in the right angle semi-circle, the section of outer ring 1 and inner ring 5 the same sides just form one L shaped along putting one inverted pair; In addition, annular groove is offered in the upper edge hole position of 1 cylinder ring body and oral area position, inner ring 5 cylinder ring body lower edge in the outer ring, to install Stamping Steel Ribbon 3 and lower seal bar 6, prevents that the rainwater dust from getting into raceway; During installation, with outer ring 1 and inner ring 5 corresponding suits, the roller 4 of from plugging hole, in raceway, packing into successively, roller one horizontal one perpendicular cross arrangement finishes up to filling, blocks plugging hole with stopping up 7, taper pin 8 is installed is then located obstruction 7.
