Abstract
The utility model relates to a vertical centrifugal casting machine main bearing cooling device, which belongs to forming portions of a centrifugal casting machine. The cooling device can work to reduce temperature rise when a main bearing works, thereby prolonging the service life of the main bearing, improving production efficiency and safety performance of equipment and simultaneously lowering manufacturing cost. The technical scheme adopted by the device includes that a sealed insetting sleeve is installed inside a centrifugal casting machine box body and outside an outer circle of the main bearing; an annular cavity is formed between the outer wall of the insetting sleeve and the inner wall of the box body; the lower portion of the cavity is sealed by a sealing ring; a water inlet pipe and a water draining pipe are mounted on the upper portion of the insetting sleeve; cooling water is injected through the water inlet pipe; a cooling zone is formed inside the cavity to provide cooling environment for the bearing; hot water after heat exchange is drained from the water draining pipe and carry away heat; and circulated refrigeration ensures normal work of the bearing. The cooling device is used for the vertical centrifugal casting machine main bearing to reduce the temperature rise when the main bearing works.
Description
Technical field
The utility model relates to centrifugal casting machine, specifically is a kind of vertical centrifugal-casting machine base bearing cooling device.
Background technology
Present most of vertical centrifugal-casting machine base bearing when producing foundry goods generates heat easily, and its reason one is the excessive and rotation and cause intensification at a high speed of carrying, and the 2nd, the alloy liquid temp of cast passes to bearing and causes intensification.Because temperature rise is too fast and higher, causes the base bearing life-span to shorten fast, thereby need often to change base bearing.This had both strengthened the input of consumable accessory, had reduced the operating efficiency of equipment again.The too high potential safety hazard that also exists of base bearing temperature rise in addition.Therefore control the too fast intensification of base bearing, improving base bearing service life, reducing accident risk is urgent problem in the production process.
Summary of the invention
Too fast for base bearing temperature rise in the control vertical centrifugal-casting machine production process, guarantee equipment safety operation, enhance productivity that the utility model provides a kind of vertical centrifugal-casting machine base bearing cooling device, effectively solves these problems.
For realizing above-mentioned purpose of the present utility model, take following technical scheme, this device converts centrifugal casting machine, increasing proprietary part by the part parts of centrifugal casting machine host and institute constitutes, the parts of described main frame have the centrifuge support, the mould ring flange, the centrifuge casing, centrifuge principal axis, the bearing upper press cover, isolate positioning sleeve and base bearing, described proprietary part is sealed edge cover and water inlet pipe and water outlet pipe, base bearing is aligning base bearing and thrust base bearing, the two is through isolating the positioning sleeve location and installation on centrifuge principal axis, sealed edge cover is installed in the outside of base bearing outer ring, sealed edge cover is fixed on the centrifuge support by the centrifuge casing, form an airtight toroidal cavity between sealed edge cover outer wall and centrifuge cabinet wall, ozzle is pressed in sealed edge set upper side, connects water inlet pipe and water outlet pipe.Work advances from water inlet pipe to inject cooling water, forms annular salband in cavity, provides cooler environment by heat exchange to bearing, and bearing is forced cooling, and the hot water after heat exchange is discharged from drainpipe, has guaranteed the operate as normal of bearing.
The utility model beneficial effect is as follows: 1. the cooling water that utilize to flow carries out heat exchange, and good cooling results has effectively reduced the temperature rise of bearing, has prolonged the service life of bearing, has improved efficiency of equipment; 2. owing to prolonged the service life of bearing, reduced the loss of bearing,, improved the business economic benefit so reduced production cost; 3. because bearing, has been avoided the hard seize accident of bag due to the base bearing Yin Gaowen, the security that has improved equipment in low temperature environment work.
