Abstract
The invention relates to a sealed rolling bearing for a falling-sand roller supporting-wheel device. The falling-sand roller supporting-wheel device comprises a supporting-wheel body, a nylon sleeve, a supporting-wheel shaft, a supporting-wheel supporting seat and a pressure cover. Two rolling bearings are respectively installed at both ends of an inner cavity of the supporting-wheel body between the supporting-wheel body and the supporting-wheel shaft, and two sealing covers are respectively installed at the outer sides of the two rolling bearings. An isolating sleeve I is sleeved on the supporting-wheel shaft between the two rolling bearings. Two isolating sleeves II are respectively sleeved on the supporting-wheel shaft at the outer sides of the two rolling bearings. Two fastening nuts are respectively screwed on the supporting-wheel shaft at the outer sides of the two isolating sleeves II. Two lip-shaped bidirectional-rotating sealing rings are respectively installed in the two rolling bearings, the two isolating sleeves II and the concave parts at the inner sides of two sealing covers between the two sealing covers. The rolling bearings are sealed in the inner cavity of the supporting-wheel body through the sealed rolling bearing, so that dust or sand can not enter the rolling bearings, thereby the service lives of the rolling bearings are greatly prolonged. The service life of the falling-sand roller supporting-wheel device is also greatly prolonged.
Description
Technical field
The present invention 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 sealed rolling bearing that the purpose of this invention is to provide a kind 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.
Technological scheme of the present invention 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.
Advantage of the present invention has provided 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.
