Abstract
The utility model relates to a sealing rubber strip for sealing box bodies of a gear box class, which comprises a fixed inserting part, wherein, the top of the fixed inserting part is provided with one or more than one radial sealing unit, the side face of the fixed inserting part is provided with axial sealing units, and each sealing unit and the fixed inserting part form a strip-shaped structure which has easy positioning and arrangement as well as has the sealing effect of an O-shaped ring. After the side face of the inserting part is additionally provided with the axial sealing units extending laterally, the utility model can also generate the axial dynamic sealing effect of an end face. Adopting the structure, a radial dynamic sealing point between machine oil in a box and a main axle in a bearing shell is provided with a radial static seal and an axial dynamic seal two seals outside the bearing shell so that the utility model nicely blocks the machine oil flowing into the line of the dynamic seal in the bearing shell and has better ensuring effect on the normal running of locomotives.
Description
Technical field
The utility model belongs to field of mechanical technique, relates in particular to a kind of rubber weather strip that gear-box class casing is sealed.
Background technique
In the installing locomotive gear cases, need radially static seal between the sealing bearing bush of casing and axle, in order to avoid the gear lubrication machine oil of bottom half seals in the motive sealing between bearing shell and the gearbox output shaft.Otherwise in a single day the machine oil of thickness seal in motive sealing place, can cause that just bearing shell heats up rapidly, causes mechanical accident.Existing radially static seal mostly adopts the felts Stamping Steel Ribbon, because the felts Stamping Steel Ribbon sucks the dirt material easily in long-term using process, makes felt progressively lose elasticity, causes poorly sealedly, has influenced the normal use of gear-box.
The model utility content
The purpose of this utility model is to provide a kind of can both play radially static seal, can play the rubber weather strip of axial motive sealing effect simultaneously again.
For achieving the above object, the utility model has adopted a kind of rubber weather strip, this Stamping Steel Ribbon comprises fixedly setting-in portion, fixedly setting-in portion top is provided with one or more radial seal unit, fixedly setting-in portion side is provided with the axial seal unit, each sealing unit and fixedly setting-in portion be strip structure.
Described radial seal unit is a semi-cylindrical shape.
The home position of described semi-cylindrical shape radial seal unit is provided with a through hole.
The sealing surface of described axial seal unit is a semi-cylindrical shape.
Described semi-cylindrical oblique crank Z is provided with a through hole to the sealing unit home position.
The sealing surface of described axial seal unit is single zigzag structure.
The sealing surface of described axial seal unit is two zigzag fashion sealing surfaces.
The cross section of described axial seal unit is for to collude the wiper seal face of stretching to oblique below.
Because the top of this rubber weather strip is a sealing surface, the bottom is a setting-in portion, and this structure had both been located easily and laid, and had the sealing effect of " O " type circle again concurrently.After sealing part added concentric circle, the sealing surface high resilience had bigger distortion leeway, and adaptive ability is stronger.After the side of setting-in portion adds the axial seal unit that side stretches, can produce the axial motive sealing effect of end face again.As can be seen, adopt this structure, dynamic radial seal place from inner box-machine oil to the bearing shell inner main axis is provided with radially static seal and the axial motive sealing two seals outside the bearing shell, blocked the circuit that machine oil seals in motive sealing in the bearing shell well, and the normal operation of locomotive is had the better guarantees effect.
