Description
Technical field
The utility model relates to a kind of mechanical transmission, the contactless non-return device of a kind of oil lubrication specifically.
Background technique
Contactless non-return device has been widely used in the mechanical transmission technical field.At present, such non-return device is mainly used in noria, Belt Conveyors etc. needs on the equipment of check.What contactless non-return device adopted is the voussoir of laying particular stress on, and when surmounting at a high speed, because the centrifugal action voussoir flies away from working surface, does not all contact with inside and outside ring; When the rotating speed reduction needed check, voussoir recovered to contact with inside and outside ring through torsion spring.But traditional contactless non-return device generally adopts grease lubrication; Usually too much generate heat, and general lubricating grease viscosity reduces along with ambient temperature and change is big, easily the viscous voussoir owing to adding lubricating grease; Cause voussoir slow in reacting; When surmounting at a high speed, voussoir can not break away from contacting of inside and outside ring and causes quick wearing and tearing, and reliable check can not in time reset again when the speed reduction needs check.And long-term use can make the lubricating grease sex change dry and hard, causes voussoir clamping stagnation or bad connection easily, thereby causes the inefficacy of when suffering impulsive load, skidding of contactless non-return device.
Adopt oil lubrication can effectively overcome the defective of contactless non-return device grease lubrication.But the maximum problem of oil lubrication is necessary reliable sealing, because such contactless non-return device generally is used in high speed situation, so adopt common rotary shaft lip seal very easily to damage, needs running check to change, and is difficult to extensive popularization.
Summary of the invention
The purpose of the utility model is not change under the prerequisite of former contactless non-return device installation dimension, and a kind of reasonable in design is provided, and manufacturing process is simple, seals the contactless non-return device with reliable mechanical seal arrangement reliable, with low cost.
For achieving the above object, the utility model is realized in such a way.The utility model is made up of connecting lever, outer shroud, voussoir, torsion spring, pin, maintenance circle, ventilative plug screw, stifle, bearing, oil ga(u)ge, baffle plate, disc, O RunddichtringO, interior ring; It is between interior ring and outer shroud, to be provided with some groups of voussoirs, torsion spring and pin, and its position keeps through a pair of maintenance circle.
Keep that voussoir, torsion spring and the equally distributed some apertures of pin are arranged on the circle, and a pair of maintenance circle is riveted into one through pin.
The end face of baffle plate is processed with the labyrinth sealing groove, and oil sump is arranged at the bottom, and unidirectional return port is arranged at top.
There is disc the both sides of disc, and oil scraping teeth is arranged at the top.
The advantage of the utility model is that disc has oil resistance and oil return dual functions, and unidirectional backflow aperture is arranged on the baffle plate, and connecting lever, baffle plate, disc are formed the non-contact mechanical seal with oil resistance, oil return function.Compact structure, reasonable in design is made simply, and sealing is reliable, low cost of manufacture.Can effectively solve the defective of contactless non-return device grease lubrication under the high speed operation state and the sealing difficult problem of oil lubrication, it is fit to be installed on the operating mode that a few thing condition is poor, load variations is complicated uses.

Embodiment
Below in conjunction with embodiment the utility model is done further to specify:
The utility model is made up of connecting lever (1), outer shroud (2), voussoir (3), torsion spring (4), pin (5), maintenance circle (6), ventilative plug screw (7), stifle (8), bearing (9), oil ga(u)ge (10), baffle plate (11) disc (12), O RunddichtringO (13), interior ring (14); It is between interior ring and outer shroud, to be provided with some groups of voussoirs, torsion spring and pin, and its position keeps through a pair of maintenance circle.Keep that voussoir, torsion spring and the equally distributed some apertures of pin are arranged on the circle, and a pair of maintenance circle is riveted into one through pin.The end face of baffle plate is processed with the labyrinth sealing groove, and oil sump is arranged at the bottom, and unidirectional return port is arranged at top.There is disc the both sides of disc, and oil scraping teeth is arranged at the top.
The utility model can be divided into three parts: non-return device main body, connecting lever side and stifle side.The non-return device main body is aided with and is kept circle (6) and bearing (9) composition by outer shroud (2), interior ring (14) and equally distributed therebetween some groups of voussoirs (3), torsion spring (4) pin (5), realizes that the non-contact of the utility model surmounts and the check function.The connecting lever side is made up of connecting lever (1), disc (12), O RunddichtringO (13), baffle plate (11), and its sealing function implementation is: primary seal: through baffle plate (11) with bearing (9) with keep circle (6) and go up equally distributed voussoir (3), torsion spring (4) pin (5) and wait the parts that need to lubricate and the Sealing of connecting lever (1) and disc (12) to separate; Secondary seal: the labyrinth sealing of forming through baffle plate (11) connecting lever (1) and disc (12) stops oil leak; Three grades of sealings: through twice blocking-up of disc oil leak path of disc (12) both sides; Level Four sealing: the oil scraping teeth through disc (12) top will leak fluid and take up and send the working room again back to through the unidirectional return port on the baffle plate (11) from the oil sump bottom the closed chamber.The complete non-contact of whole seal process, zero wearing and tearing, zero heating, and lubricant oil zero loss.The stifle side is made up of ventilative plug screw (7) of stifle (8) and oil ga(u)ge (10); Stifle (8) is realized the sealing of the utility model one side; Can give the utility model oiling and keep internal oil pressure stable through the ventilative plug screw (7) on its top, oil ga(u)ge (10) is positioned at the reasonable altitudes on the stifle (8), and the highest minimum scale is arranged on it; Guarantee the lubricant oil oil mass at zone of reasonableness, and convenient observation and operation.
