Description
Technical field
The utility model relates to a kind of shaft end seal bearing device, particularly relates to a kind of seal support device of mixing drum internal vibration device.
Background technique
Stirrer is the core component of concrete batch plant, and the usability of stirrer affects working efficiency and the operation quality of whole mixing plant to a great extent.And in the design of stirrer, need emphasis it is considered that shaft end seal.Shaft end seal is positioned on the stirring shaft of stirrer, is between stirrer housing and stirring shaft, is be between mixing blade (in housing) and spring bearing (housing is outer) in the lengthwise position of stirring shaft.Its effect be prevent stirrer operationally concrete mud extruded outside housing by surely dynamic gap (being namely fixed on the gap between element on housing and rotatable member), be commonly called as axle head spillage.Because containing sand or like solid in mud, once clamp-on surely dynamic gap in housing, will wear and tear surely dynamic element.And if mud plugs lubrication hydraulic fluid port, mud divides sclerosis at surely dynamic inner space, and wearing and tearing will be accelerated, and also quickening is caused axle head spillage to the damage surely moving element.If mud breaks through support bearing assembly sealing, enter and destroy bearing, complete machine will be caused normally to work.
Early stage agitator shaft end seal is the structural drawing of Combined type shaft end seal, also known as open type labyrinth seal.Ensure that between cover plate and back-up ring, reasonably gap is the key point of whole shaft end seal, relative area is comparatively large, and whether what control in processing and assembling process gets well, and will affect the effect of sealing to a great extent.Circular gap in addition between stirring shaft and cover plate also needs reasonably to design.Its sealing principle is: first is the seal action of the lubricant oil be full of in surely dynamic gap, the surely dynamic gap of appropriate design, the full lubricant oil of pump (the general method adopting hand pump) in the cavity in the surely dynamic gap of stirrer work forward direction, by oil pump interrupted charging-up lubricant oil in the cavity between rotor and fixed block in work, working part is lubricated, hinder mud to enter shaft end seal simultaneously, play the improved action of sealing concrete mixer shaft end seal, this is also primary seal.Second is the seal action of fluctuate hermetical ring, and the gap between control change hub and slip ring boss within the limits prescribed, uses in pairs.When assembling, O RunddichtringO is subject to axial compression and produces distortion, thus between two rings, produces certain pressure, and two ring end faces fit tightly and form sealing.Meanwhile, fluctuate hermetical ring forms certain cavity, to store lubricant oil in surely dynamic gap.3rd road is the seal action of J type sealing, and its Main Function prevents the lubricant oil of fluctuate hermetical ring inner chamber to external leakage.
In addition on agitator shaft end seal, also have and use V-shaped seal ring, its principle is, to stirrer as end face seal, V-shaped seal ring is a kind of elastic rubber sealing ring of axial action, as rotating shaft without means of press seals, sealing lip has good mobility and adaptability, can the large tolerance of compensate for slower and augular offset, internal grease or fluid can be prevented to outward leakage, also can prevent extraneous dabbling or the immersion of dust.
Above-mentioned sealing configuration uses on horizontal axis stirring apparatus can obtain good sealing effect, but for vertical shaft stirring apparatus, above-mentioned sealing configuration all exists that operational safety is low, sealing effect is bad, the problems such as easy generation seepage, therefore, for the shaft end seal of vertical shaft type stirring apparatus, remain a difficult problem urgently to be resolved hurrily.
