Abstract
The utility model provides a seal rolling bearing of a ramoff roller riding wheel device. The ramoff roller riding wheel device includes a riding wheel body, a nylon sleeve, a riding wheel shaft, a riding wheel support and a gland, wherein a rolling bearing is mounted at each end of a riding wheel body inner chamber between the riding wheel body and the riding wheel shaft; sealing covers are mounted on the outer sides of the two rolling bearings; spacer sleeves I are sleeved on the riding wheel shaft between the two roller bearings; and spacer sleeves II are sleeved on the riding wheel shaft on the outer sides of the two rolling bearings; clamp nuts are screwed and installed on the riding wheel shaft on the outer sides of the two spacer sleeves II; and two lip-shaped bidirectional rotary seal rings are mounted in inner side concave parts of the two sealing covers between the two rolling bearings and the two sealing covers as well as between the two spacer sleeves II and the two sealing covers. According to the utility model, the rolling bearings are sealed in the riding wheel body inner chamber, and lime sand cannot enter the rolling bearings, so that the service lives of the rolling bearings are greatly prolonged, and the service life of the ramoff roller riding wheel device is greatly prolonged.
Description
Technical field
The utility model relates to a kind of rolling bearing, the sealed rolling bearing of the knockout cylinder riding wheel apparatus of foundry equipment in particularly a kind of machining.
Background technique
Being used for the unpack device of knockout of high pressure molding production line in the foundry machinery has the branch of mode of vibration and drum type, wherein drum type unpack the device of knockout with advantages such as low noise, running are steady by extensively employing.
The unpacking sand shake-out device using of traditional drum type is: there are two circular tracks front and back, and each circular track supports by two riding wheel apparatus.Have four riding wheel apparatus supportings below two circular tracks.The knockout cylinder of foundry equipment slowly rotates and the knockout of unpacking on circular track.
The external edge of each support roller of the riding wheel apparatus of the unpacking sand shake-out device using of traditional drum type coats the nylon jacket of a layer thickness 50 millimeter.A supporting-roller shaft is installed in the middle of each support roller body.Rolling bearing supporting in the inner chamber that the two ends of supporting-roller shaft are made up of bearing spider and gland.Be respectively installed with two spacers on the rolling bearing both sides on the supporting-roller shaft and be used for fixing the position between support roller body and the rolling bearing.Spacer and supporting-roller shaft and support roller body together rotate during work.But when the support roller body was lived circular track and knockout cylinder and rotated with circular track and knockout cylinder at jacking, the axial float power of knockout cylinder also made the support roller body carry out axial moving, and the support roller body always moves to same direction.Moving of support roller body; Just make between spacer and the rolling bearing and the support roller body of an end in the other direction and produce the gap; Sand-lime very easily gets in the rolling bearing from the gap and blocks rolling bearing it can not be rotated in the support roller bearing flexibly, causes the wearing and tearing of rolling bearing to damage.So just greatly influenced the working life of rolling bearing.Also greatly influenced the working life of knockout cylinder riding wheel apparatus.
Summary of the invention
The purpose of the utility model provides a kind of sealed rolling bearing of knockout cylinder riding wheel apparatus.The sealing rolling bearing is sealed in the support roller intracoelomic cavity rolling bearing, and sand-lime can't be got in the rolling bearing, thus the working life of greatly having improved rolling bearing.Also greatly improved the working life of knockout cylinder riding wheel apparatus.
The technological scheme of the utility model is: a kind of sealed rolling bearing of knockout cylinder riding wheel apparatus.Its knockout cylinder riding wheel apparatus bag words support roller body, nylon jacket, supporting-roller shaft, support roller bearing and gland.The support roller intracoelomic cavity is arranged between support roller body and supporting-roller shaft.A rolling bearing is respectively installed at support roller intracoelomic cavity two ends.Sealing cover all is equipped with in the outside at two rolling bearings at support roller intracoelomic cavity two ends, two sealing covers by screw on the support roller body.Support roller body and sealing cover rotate around supporting-roller shaft through rolling bearing.Be set with the spacer I on the supporting-roller shaft between two roller bearings.All be set with the spacer II on the supporting-roller shaft in the two rolling bearings outside, all be installed with tightening nut on the supporting-roller shaft in the spacer II outside.Spacer I and two spacer II are fixed two rolling bearings tightly it can not be moved axially on supporting-roller shaft.The two-way rotating seal ring of two lips is installed in respectively in the two sealing cover inner recess between two rolling bearings, two spacer II and two sealing covers.The two-way rotating seal ring of lip can seal up the space between spacer II and the sealing cover.
The utility model has the advantages that the sealed rolling bearing that a kind of knockout cylinder riding wheel apparatus is provided.The sealing rolling bearing is sealed in the support roller intracoelomic cavity rolling bearing, and sand-lime can't be got in the rolling bearing, thus the working life of greatly having improved rolling bearing.Also greatly improved the working life of knockout cylinder riding wheel apparatus.
