Description
Technical field
The utility model belongs to and relates to a kind of chain, particularly novel seal chain.
Background technique
In prior art, sealed chain is made up of inner plate, outer plate, axle sleeve, bearing pin and O RunddichtringO etc.Wherein, O RunddichtringO is compressed in inner plate, between outer plate and axle sleeve, this forms an airtight space, and the grease between axle sleeve and bearing pin can not be overflowed in operation process.
When reality uses, the elasticity of seal ring, wear resistance, sealing play an important role the working life to chain.And O RunddichtringO has certain amount of deformation after being extruded, although to be price low for its advantage, this seal ring wear-resisting property is poor, and grease volatilization rear chain rate of wear in unlubricated situation is accelerated, and cannot meet the life requirements of market to high-intensity sealing chain.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes the novel seal chain of length of a kind of life-span.
The purpose of this utility model realizes by following technical proposal: novel seal chain, combined successively by several chain units, each described chain unit include just to the two pieces of inner plates arranged and two inner plates be fixed together by an axle sleeve, outer plate is equipped with and two outer plates are fixed together by a bearing pin outside two inner plates, described axle sleeve is set on bearing pin, it is characterized in that, seal ring one and seal ring two is equipped with between the inner plate and outer plate of the same side, described seal ring one is enclosed within axle sleeve, and seal ring two is enclosed within seal ring one, described seal ring one and the both ends of the surface of seal ring two are plane, and the both ends of the surface of seal ring one and seal ring two recline with inner plate and outer plate respectively, described seal ring one is fixed with inner plate, and seal ring two and outer plate are fixed, the end face that seal ring one contacts with outer plate is provided with oil storage tank one in the form of a ring, and oil storage tank one is coaxial with seal ring one, and the end face that seal ring two contacts with inner plate is provided with oil storage tank two in the form of a ring, and oil storage tank two is coaxial with seal ring two.
During normal use, oil storage tank one, oil storage tank two and be all filled with lubricant grease between axle sleeve and bearing pin.
By arranging the seal ring one be enclosed within axle sleeve and the seal ring two be enclosed within seal ring one, extraneous path is evaporate into from shoe cream room to extend grease, thus increase the difficulty of grease volatilization, to extend the time that the contacting point of grease to axle sleeve and bearing pin is lubricated, thus reduce the wearing and tearing of axle sleeve and bearing pin, to improve the life-span of this sealed chain; Secondly, both ends of the surface again by arranging seal ring one and seal ring two are plane, and the both ends of the surface of seal ring one and seal ring two recline with inner plate and outer plate respectively, effectively to increase the area of contact of seal ring one and seal ring two and inner plate and outer plate, thus extend grease evaporate into external world path from shoe cream room further, to strengthen the difficulty of grease volatilization, thus improve the life-span of this sealed chain further.The end face that seal ring one contacts with outer plate is offered the oil storage tank one for storing grease, and the oil storage tank two end face to contact with inner plate at seal ring two offered for storing grease, because grease itself possesses the effect of isolated gas, to increase seal ring one and outer plate and seal ring two and the sealing be connected between inner plate, thus increase the difficulty of grease volatilization further, then effectively improve the life-span of this chain; Meanwhile, under the effect of grease, effectively can reduce seal ring one and inner plate and the friction between seal ring two and outer plate, thus reduce the loss of seal ring one and seal ring two, then improve the life-span of this chain further.
In above-mentioned novel seal chain, on described seal ring one, cover has the support ring be made up of rigid material, support ring is between seal ring one and seal ring two, and this support ring parallels with described inner plate, and described seal ring one and seal ring two all fix with described support ring.
Seal ring one and seal ring two are held together by support ring, facilitate the composition of this sealed chain.Meanwhile, that support ring is located at seal ring one and seal ring two and parallel with inner plate, certain iris action is played to the flowing of gas, thus increases the difficulty of grease volatilization, then improve the life-span of this chain.
In above-mentioned novel seal chain, the madial wall of described seal ring two and the outer side wall of seal ring one are respectively equipped with annular slot one and annular slot two, annular slot one and annular slot two all match with support ring, and the both sides of support ring are embedded in annular slot one and annular slot two respectively.
The both sides of support ring are embedded in annular slot one and annular slot two respectively, the i.e. end face of support ring and the inwall tight abutment of annular slot one and annular slot two, formed to make the contacting point of the both ends of the surface of support ring and seal ring one and seal ring two and seal comparatively reliably, thus strengthen the difficulty of grease volatilization further, then improve the life-span of this chain.
In above-mentioned novel seal chain, described oil storage tank one and the cross section of oil storage tank two all triangular in shape.
Adopt above-mentioned structure, make seal ring one and seal ring two be more prone to deformation occurs, the grease be stored in oil storage tank is better lubricated the contacting point of seal ring and inside and outside carrier bar, thus improves the life-span of this chain further.
Compared with prior art, this novel seal chain has the following advantages:
1, by arranging the seal ring one be enclosed within axle sleeve and the seal ring two be enclosed within seal ring one, extraneous path is evaporate into from shoe cream room to extend grease, thus increase the difficulty of grease volatilization, to extend the time that the contacting point of grease to axle sleeve and bearing pin is lubricated, thus reduce the wearing and tearing of axle sleeve and bearing pin, to improve the life-span of this sealed chain; Secondly, both ends of the surface again by arranging seal ring one and seal ring two are plane, and the both ends of the surface of seal ring one and seal ring two recline with inner plate and outer plate respectively, effectively to increase the area of contact of seal ring one and seal ring two and inner plate and outer plate, thus extend grease evaporate into external world path from shoe cream room further, to strengthen the difficulty of grease volatilization, thus improve the life-span of this sealed chain further.
, the end face to contact with outer plate at seal ring one is offered oil storage tank one for storing grease, and the oil storage tank two end face to contact with inner plate at seal ring two offered for storing grease, because grease itself possesses the effect of isolated gas, to increase seal ring one and outer plate and seal ring two and the sealing be connected between inner plate, thus increase the difficulty of grease volatilization further, then effectively improve the life-span of this chain; Meanwhile, under the effect of grease, effectively can reduce seal ring one and inner plate and the friction between seal ring two and outer plate, thus reduce the loss of seal ring one and seal ring two, then improve the life-span of this chain further.
, by arranging support ring between seal ring one and seal ring two, and the both sides of support ring are embedded in annular slot one and annular slot two respectively, good supporting effect can not only be played to seal ring one and seal ring two, the contacting point of the both ends of the surface of support ring and seal ring one and seal ring two can be made again to be formed seal comparatively reliably, to increase the difficulty of grease volatilization, improve the life-span of this chain.
