Technical background
Bearing is the supporting part that Axial parts is arranged in specific axis bearing.Be a kind of important component in contemporary machinery, its major function is supported mechanical solid of rotation, reduces the friction factor in its movement process, and ensures rotating accuracy.At present, for different duty requirements, create bearing and the mounting arrangements mode thereof of varied type.
Ploughing machine due to working environment relatively severe, working environment directly contacts with earth dust.And can be subject to axially and the effect of radial power at the running middle (center) bearing of cultivated cutter simultaneously, need the rigidity of the mounting structure ensureing bearing enough good.In addition, ploughing machine adopts the independent mounting type of each cultivated cutter mostly, it is also proposed certain requirement to the miniaturization of mounting structure and convenience.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of bearing structure of tractor-ploughing cutter of ploughing.
For a bearing structure for tractor-ploughing cutter of ploughing, it is characterized in that comprising bearing support, axle, axle sleeve, two bearing inner races, two tapered rollers, two bearing outer rings, retainer, cone spacer, outer ring spacer, check ring, dust cover, seal rings; Axle is provided with bearing inner race, cone spacer, bearing inner race, axle sleeve to the end successively from tail, two bearing inner races are all placed with retainer, retainer is used for being uniformly distributed of tapered roller, the outer installation shaft bearing outer-ring of tapered roller, check ring is arranged in bearing support interior grooves, be positioned at the bearing outer ring of axle afterbody and check ring side near, check ring opposite side and outer ring spacer near, outer ring spacer and another bearing outer ring near, be provided with seal ring between axle sleeve and bearing support, bearing support afterbody is provided with dust cover.
Further, the mounting type of two tapered roller bearings, for install back-to-back, makes load center be in outside bearing axis, and point of force application span becomes large, and the rigidity of cantilever is better.
Further, seal ring between axle sleeve and bearing support adopts six lip cartridge seals, coordinated with bearing support by exterior seal ring, middle seal ring, middle seal ring coordinates with axle sleeve, inner seal ring is clipped in middle seal ring and exterior seal ring, can effectively stop external dust or cement enter in body and effectively prevent the grease in body from going out from body internal leakage.
Further, between cone spacer and outer ring spacer, leave space, make an addition to storage for grease.
Use the utility model, the mounting type of bearing support is simple, required precision for component is low, have employed the Back-to-back installation of separable tapered roller bearing, load center is made to be in outside bearing axis, point of force application span becomes large, promotes the rigidity of cantilever, cultivated cutter is operated more stable.The utility model adopts lip cartridge seal structure simultaneously, and seal is to form interference fit between bearing support end face.External dust or cement can be effectively stoped to enter in body.Also can effectively prevent the grease in body from going out from body internal leakage, simultaneously low to requirements of installation space, low to the requirement on machining accuracy at mounting groove and sealing position.The utility model mounting structure is reliably compact, can meet the installation requirements of multiple ploughing machine for cultivated cutter.
