Detailed description of the invention
Being described in further detail technical solution of the present invention with specific embodiment below in conjunction with the accompanying drawings, so that those skilled in the art can be better understood from the present invention and can be practiced, but illustrated embodiment is not as a limitation of the invention.
A kind of land leveller back axle dry type self-lubricating sheave limit assembly, as illustrated in fig. 1 and 2, it should be noted that: for the ease of describing and understanding, the left side in figure is defined as B end by unification, and the right side in figure is defined as A end.
Wheel limit assembly includes hub spindle 10, described hub spindle 10 is the integral structure including wheel hub with axletree, i.e. hub spindle 10 has the effect of axletree and wheel hub simultaneously, changes the split-type structural of common wheel hub Yu axletree into monoblock type, it is ensured that wheel hub does not comes off during using.One end A end (i.e. right-hand member in Fig. 1) of described hub spindle 10 is provided with brake assembly 5 and other end B end (i.e. left end in Fig. 1) stretches in the tandem-driving bogie 12 that can accommodate fluid.
The B end of described hub spindle 10 is provided with sprocket wheel 1, and during work, the gear oil oil level 14 in tandem-driving bogie 12 is as it is shown in figure 1, sprocket wheel 1 contacts with gear oil.The housing 4 of integral type it is provided with between sprocket wheel 1 and the A end of hub spindle 10 of described hub spindle 10, it is provided with between the A end of clutch shaft bearing 3 and housing 4 and the A end of hub spindle 10 between B end and the sprocket wheel 1 of housing 4 and second bearing 8 is installed, the top of the B end of housing 4 is provided with the oil-through hole 13 being connected with tandem-driving bogie 12, seals and arrange and form sealing cavity between housing 4 and hub spindle 10.
Housing is overall structure, is provided with bearing between housing two ends and hub spindle, and bearing is taper roll bearing, and i.e. clutch shaft bearing 3 and the second bearing 8 are all taper roll bearings.Sprocket wheel 1 is connected with hub spindle 10 by spline, and is fixed on the positioning by expansion sleeve.
The gear oil rotarily driven in tandem-driving bogie by sprocket wheel in practical work process splashes along with the rotation of sprocket wheel, the gear oil splashed flows into two ends equipped with in the cavity of bearing by the oil-through hole above housing, in order to ensure that the gear oil in cavity does not spills during using, housing A end and hub spindle A end wheel hub use float grease seal to seal, float grease seal has good adaptability for working condition, lubricating oil in cavity also ensure that ruggedness and the reliability of float grease seal, hub spindle B end in application process owing to rising up into back axle tandem-driving bogie casing, then can carry out sealing both may be used only with common outside framework oil seal.The bearing at the lubricating oil Castor Oil housing two ends in sealing cavity, so greatly improves durability and the reliability of bearing.Power is inputted by chain sprocket, and sprocket wheel driven wheel hub axle rotates thus drives tyre rotation.
Also including brake drum 7 in Fig. 1, described brake assembly 5 is connected with housing 4 by screw 6 to be fixed, and brake drum 7 is connected with hub spindle 10 by rim bolt 11 and rotates with hub spindle 10 and rotate.Brake drum rotates along with hub spindle, produces Relative friction and realizes braking function: during braking between shoe brake and the brake drum in brake, and brake fluid promotes shoe plate processed to produce with brake drum in entering brake assembly, thus realizes braking；After end of braking, in brake assembly, return spring promotes shoe plate return processed, shoe plate processed and brake drum distress resolves, then end of braking.
The lubrication of clutch shaft bearing 3 and the second bearing 8 can drive the gear oil in tandem-driving bogie 12 to splash with the rotation of sprocket wheel by the sprocket wheel 1 being arranged on hub spindle 10 when high speed rotating, the gear oil splashed lubricates clutch shaft bearing 3 and the second bearing 8 in flowing into housing by the oil-through hole above housing 4, thus realize self-lubricating, exempt daily grease lubrication.
The invention has the beneficial effects as follows:
1, the gear oil in clutch shaft bearing and the second bearing use tandem-driving bogie is lubricated, and is substantially reduced lubrication frequency, and only need to regularly replace gear oil can meet bearing lubrication requirement, and bearing is the most sufficiently lubricated simultaneously, is greatly improved bearing service life.
2, this dry type self-lubricating sheave limit assembly can separately machined assemble, it is possible to being independently designed according to the different working condition requirements of different land leveller types, can select according to actual needs in the design process of land leveller back axle, structure is more flexible.
3, wheel hub and axletree use monolithic construction, housing to be also adopted by integral structure, ensure that wheel hub does not in use have to come off, whole limit assembly of taking turns is independent of land leveller back axle Design and Machining, it is easily achieved standardization, seriation, and greatly reduce the difficulty of processing of land leveller back axle, in application process, wheel limit assembly is separately machined complete after, it is only necessary to carry out being connected with land leveller back axle tandem-driving bogie by bolt.
These are only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the invention and accompanying drawing content to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, is the most in like manner included in the scope of patent protection of the present invention.
