Abstract
The utility model discloses a novel rubber ball pin which is characterized in that an outer sleeve and a retainer ring are formed into a whole through the rubber die pressing, a self-lubricating bearing is sleeved on a mandrel, sealing rings are arranged on both ends of the mandrel and seal the mandrel and the outer sleeve, a retainer ring used for a shaft is arranged in a groove of the mandrel, the retainer ring used for a shaft realizes locating the outer sleeve on the mandrel, and both the outer sleeve and the retainer ring are columnar tube structures. Through the arrangement, the ball pin is a torsional rubber ball pin which is easy to replace and whose mandrel can automatically rotate and service life is improved.
Description
Technical field
The utility model relates to a kind of auto parts and components, definite a kind of propelling rod new construction rubber sphere pin of saying so.
Background technology
Usually, what the propelling rod that China produces used is rubber vulcanization type ball pin, most of ball latch structure is that the ball gold-sprinkled belongs to skeleton and the moulding of back-up ring molded vulcanization, the propelling rod housing of in fitting process, earlier the ball pin being packed into, with special tooling housing is put into back-up ring in the hole then, with frock the hole is pressed in the circlip groove with back-up ring at last.Because propelling rod ball pin belongs to consumable accessory, dismounting all need be used special tooling in the replacing process, for general repair factory replacing very loaded down with trivial details, often adopt the mode that whole propelling rod changed, cause very big waste.
Summary of the invention
The purpose of this utility model just provides a kind of being easy to and changes, but the torsional mode rubber sphere pin that mandrel can freely rotate and improve service life.
For reaching above purpose, overcoat and back-up ring are molded by rubber pattern to be one, self-lubricating bearing is sleeved on the mandrel, overcoat and self-lubricating bearing link together by interference fit, seal ring is arranged on the two ends of mandrel and mandrel and overcoat is realized sealing, and shaft block ring is arranged in the groove of mandrel, and shaft block ring realizes externally being enclosed within location on the mandrel by packing ring, overcoat and back-up ring are the cylindrical tube body structure, and mandrel and self-lubricating bearing are free-running fit.
By above setting, the utility model can be assembled very easily, only this ball pin need be pressed in the propelling rod housing and get final product, because the ball pin belongs to consumable accessory, vulcanization of rubber ball pin commonly used is because the hole existence of back-up ring, dismounting all need be used special tooling, and this new construction ball pin is easier to disassembling, assembling and replacing comparatively speaking.In addition, interior overcoat has possessed rubber sphere pin good springiness, the restorative good characteristics of compression by the vulcanization of rubber together simultaneously, makes propelling rod have characteristics such as fatigue performance is good, shock resistance is good, and is easy to change, and can be widely used in the vehicular spare parts field.
