The utility model relates to a science, simple structure, the swift simple sealing performance who detects double row sealed conical bearing of ability.
Description
Technical Field
The utility model belongs to detection device especially relates to double row sealed conical bearing gas tightness detection device.
Background
The sealing performance of a machined sealing part cannot be verified in the production and machining process of the conventional double-row sealing type conical bearing, the phenomenon of grease leakage of a product can be caused when the sealing performance is poor, or external muddy water or dust enters the inside of the bearing under a severe working environment, so that a bearing assembly fails in advance.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the unable problem of verifying of biserial sealed conical bearing's leakproofness among the prior art, provide a biserial sealed conical bearing gas tightness detection device that can detect biserial sealed conical bearing leakproofness.
The utility model provides a technical scheme that its technical problem adopted: biserial sealed conical bearing gas tightness detection device, including splint I, splint II and kerosene pond, splint I and splint II are circular, be equipped with the ring breach of placing biserial sealed conical bearing inner circle on splint I and splint II's the circle limit, be equipped with air inlet interface and the interface of giving vent to anger on splint I and splint II respectively, sealing connection has intake pipe and outlet duct on air inlet interface and the interface of giving vent to anger, be equipped with air-vent valve I in the intake pipe, and be connected with the air inlet, be equipped with barometer and air-vent valve II on the outlet duct, and be connected with the gas outlet, splint I and splint II are through locking screw centre gripping biserial sealed conical bearing.
Preferably, the annular gaps of the clamping plates I and II are provided with sealing rings with square sections.
The utility model discloses a using-way and principle: when the double-row sealed type conical bearing is used, the inner ring of the double-row sealed type conical bearing is placed in the annular gap of the clamping plate I and the clamping plate II, the clamping plate I and the clamping plate II clamp the double-row sealed type conical bearing through the locking screw rod, then the double-row sealed type conical bearing is placed in a kerosene pool, compressed air is introduced, the pressure regulating valve is adjusted, the pressure inside the bearing assembly reaches a set value, and whether bubbles overflow from the kerosene pool is observed. The utility model discloses a locking screw connects into a whole with splint I, splint II and double row sealed conical bearing, through injecting into gas to it, inside gas entering double row sealed conical bearing to use pressure regulating valve adjusting bearing internal pressure size, if the inside gas tightness of double row sealed conical bearing is poor, other will follow this outflow, and the gassing if the inside gas tightness of double row sealed conical bearing is good, will not produce the bubble in the kerosene pond.
The utility model has the advantages that: the utility model relates to a science, simple structure, the swift simple sealing performance who detects double row sealed conical bearing of ability.
