Abstract
The utility model relates to a thrust spherical plain bearing, which mainly solves the problem that the fitting of the inner hole of a shaft washer and the outer circle of a seat ring is required when the prior thrust spherical plain bearing is mounted. The thrust spherical plain bearing consists of a shaft washer (1) and a seat ring (2). The utility model has the technical proposal that the outer spherical surface of the shaft washer is extended in the direction of the back end surface of the shaft washer to the hemicycle position which is in a cylindrical surface (1), namely, the external diameter of the shaft washer is consistent to the diameter of the spherical surface; a concave braking slot (12) is arranged at the transition position of the cylindrical surface of the outer spherical surface of the shaft washer, and a concave braking slot (21) is also arranged on the side surface outside the seat ring. A new installation way is realized through changing the structure, the shaft washer and the seat ring are respectively fixed through a braking slot, thereby leading to the relative movement between the shaft washer and the seat ring to meet the installation requirements of the special mechanism.
Description
Technical field: the utility model relates to a kind of bearing, specifically, is a kind of thrust articulated bearing.
Background technique: in existing thrust articulated bearing, blowout patche internal diameter size is on width direction, and except that chamfering, consistent size matches with the stationary axle size; The blowout patche nominal outside diameter is all less than blowout patche outer spherical surface diameter; The installation method of bearing is to cooperate fixed installation by blowout patche endoporus, seat ring cylindrical, cooperates hard-wired mechanism for being not suitable for blowout patche endoporus, seat ring cylindrical, and this class bearing then can't meet the demands.
Summary of the invention: the utility model is will solve above-mentioned thrust articulated bearing and install the time, the problem that needs blowout patche endoporus and seat ring cylindrical to cooperate.The utility model thrust articulated bearing is made up of blowout patche and seat ring, and its technological scheme is, the blowout patche outer spherical surface is extended to the transition of semicircle place to blowout patche ear end face direction be the cylndrical surface, and promptly the blowout patche nominal outside diameter is consistent with its outer spherical surface diameter; At the cylndrical surface of blowout patche outer spherical surface crossover position one circle spill locking groove is arranged, one circle spill locking groove is also arranged at the close end face thereafter of seat ring outer surface.
The utility model thrust articulated bearing has been realized a kind of new mounting type by the change of structure, adopts locking groove that blowout patche and seat ring is fixing respectively, makes relative movement between seat ring and the blowout patche, is satisfied the installation requirement of special entity.
Description of drawings: Fig. 1 is the sectional view of the utility model thrust articulated bearing structure, Fig. 2 is the scheme of installation of thrust articulated bearing shown in Figure 1, is labeled as among the figure: 1-blowout patche, 11-cylndrical surface, 12-locking groove, 2-seat ring, 21-locking groove, 3-fixed plate, 4-screw, 5,6-fixed base.
Embodiment: as shown in Figure 1, the utility model thrust articulated bearing is made up of blowout patche 1 and seat ring 2, the surface that blowout patche cooperates with seat ring is an outer spherical surface, blowout patche 1 outer spherical surface extreme direction behind blowout patche is extended to the transition of semicircle place becomes cylndrical surface 11, and promptly the blowout patche nominal outside diameter is consistent with its outer spherical surface diameter; At the cylndrical surface of blowout patche outer spherical surface crossover position one circle spill locking groove 12 is arranged, one circle spill locking groove 21 is also arranged at the close end face thereafter of seat ring 2 outer surfaces.
Mounting type as shown in Figure 2, fixed plate 3 is inserted in the locking groove 12,21, utilizes screw 4 that blowout patche 1 and seat ring 2 are locked in respectively on the fixed base 5,6, fixed base is connected with other mechanism again, realize the relative movement between seat ring and the blowout patche, can satisfy the installation requirement of special entity.
Claims (1)
1, a kind of thrust articulated bearing, form by blowout patche (1) and seat ring (2), it is characterized in that: blowout patche (1) outer spherical surface extreme direction behind blowout patche is extended to the transition of semicircle place be cylndrical surface (11), be that the blowout patche nominal outside diameter is consistent with its outer spherical surface diameter, at the cylndrical surface of blowout patche outer spherical surface crossover position one circle locking groove (12) is arranged, one circle spill locking groove (21) is also arranged at the close end face thereafter of seat ring (2) outer surface.
