Abstract
Rotor with breather and anti-rotation arrangement for tire calibration arrangements that provides a suitable breather of the axle hub, and, in turn, an improved oil retention thus preventing the premature wear of internal pieces and possible accidents during its operation.
Claims10
A rotor with breather for tire calibration arrangements characterized by a block rotatably mounted on an axle having an internal air duct or passage that is in communication, by means of an internal end, with a pressurized air hose or pipe that is inside a hollow axle or pressurizes the axle interior and carries the pressurized air from an external air reservoir or tank, and, in turn, said internal air duct or passage is in communication, by means of an external end, with a transfer chamber operatively communicated with respective tire inflation or deflation valves through corresponding pipes, said rotor comprising:
- at least one bearing rotatably mounted on said axle by means of at least one rolling bearing, said block mounted, in turn, on said bearing to rotate together with said axle on which said block is fixed;
- and said bearing further comprising a pair of oil traps on a periphery thereof and between which a pair of breather guide channels is defined, said pair of breather guide channels allowing for the communication and guided passage of pressurized air to an exterior of said bearing through one of a breather passage or hole defined in a middle portion of said block.
A rotor for tire calibration arrangements according to claim 7, wherein said solid seal comprises an internal passage in communication with one of said internal air duct and said passage of the axle and with said transfer chamber.
A rotor with an anti-rotation arrangement for tire calibration arrangements characterized by a block rotatably mounted on an axle having an internal air duct or passage in communication, by means of an internal end, with a pressurized air hose or pipe that is inside a hollow axle and carries pressurized air from an external air reservoir or tank and, in turn, said internal air duct or passage is in communication, by means of an external end, with a transfer chamber that is operatively communicated with respective tire inflation or deflation valves through corresponding pipes, the rotor comprising at least one anti-rotation arrangement housed in an external part of the rotor;
- a spring held between an internal wall of an external part of the block and an end of said axle, wherein said anti-rotation arrangement comprises:
- at least one anti-rotation seat wherein a first end of said spring sits at said at least one anti rotation seat;
- at least one anti-rotation guide, the other end of said spring sits at said at least one anti rotation guide;
- at least one solid seal housed in said anti-rotation guide and kept airtight between said spring and said end of said axle;
- and
- at least one O-ring seal formed between said anti-rotation guide and said solid seal.
