The hydraulic support lower frame wheel set device comprises an axle, an axle sleeve, a wheel, an oil injection nozzle, a tapered roller bearing, a distance sleeve, a self-aligning roller bearing and an end cover. The oil injection nozzle is installed on a screw hole in a small-end side of the wheel, the end cover is installed on a large-end side of the wheel, an O-shaped sealing ring is installed between the axle and the axle sleeve, an adjusting paper pad is installed between the end face of the wheel and the end cover, both the tapered roller bearing and the self-aligning roller bearing are installed between the wheel and the axle, the distance sleeve is installed between the tapered roller bearing and the self-aligning roller bearing, the end cover and the wheel are tightened together through a hexagon socket screw, a spring washer is installed between the hexagon socket screw and the end cover, and a skeleton sealing ring and a felt sealing ring are installed inside a groove in the small-end end of the wheel and a groove of the end cover.
Description
Technical field
The utility model relates to a kind of hydraulic support undercarriage wheel to device.
Background technology
The continuous merging and reorganization of China's coal-mine enterprise at present, coal mine fully-mechanized mining working device therefor is more and more, increasing.Due to accelerating development and the driving surface requirement of removal of home fast of fully-mechanized mining equipment, corresponding stent car load carrying ability is increasing, the well damage of current hydraulic support transport vehicle, had a strong impact on the lifting of transport capacity under coal mine, and strengthened workman's labour intensity, affected the manufacturing schedule and the economic benefit that has reduced enterprise of enterprise.
Summary of the invention
The utility model object is for overcoming the deficiency of above-mentioned prior art, provides a kind of hydraulic support undercarriage wheel that overhauls convenience, good airproof performance to device.
The utility model comprises axletree and axle sleeve, wheel, zerk, tapered roller bearing, apart from cover, self-aligning roller bearing and end cap, zerk is arranged on the screw of wheel microcephaly side, tapered roller bearing and self-aligning roller bearing are installed between wheel and axletree, distance cover is arranged between tapered roller bearing and self-aligning roller bearing, O RunddichtringO is installed between axletree and axle sleeve, end cap is arranged on the major part side of wheel, adjustment paper washer is installed between wheel end face and end cap, end cap tightens together by socket head cap screw with wheel, between socket head cap screw and end cap, spring washer is installed, in wheel microcephaly holds groove and end cap groove, backbone sealing ring and felt seal ring are installed.
Wheel adopts 40Mn2 alloy steel solid forging moulding, surface hardening, and intensity is high, and wheel tread resistance to abrasion is good, and non-deformability is strong; Axletree adopts the 40Cr alloy steel of good combination property to process, and carries out modifier treatment, makes its impact resistance better, stronger, and position of bearings adopts fine grinding technology to guarantee that bearing assemble is good; Bearing uses the mode of self-aligning roller bearing and tapered roller bearing combination, has strengthened and has taken turns right axial load ability, effectively improves bearing service life, makes wheel to operation more steadily not reliably; Axle sleeve adopts tin bronze material fine limit work to form, and axle sleeve is installed the highly polished of sealing station, at utmost reduces the wearing and tearing of sealing member, and it adopts close fit with coordinating of axletree; Distance cover employing 45# high-quality steel is also uniform makes a call to 8 holes so that oiling; Sealing adopts rubber skeleton sealing, felt seal ring and O RunddichtringO combination sealing, can effectively prevent that coal dust and down-hole alkaline water from entering bearing, causes the damage of bearing; While installing in bearing, to inject grease, simultaneously also can be regularly internal by zerk oiling to wheel.
The utility model is simple in structure, easy to manufacture, good seal performance, maintenance is convenient, and oiling at any time in hydraulic support transport vehicle use procedure has reduced because sealing wheel bad and that oiling in time causes to damaging, the safety misadventure of having avoided equipment to occur in transportation, improve labor efficiency, reduced workman's labour intensity, improved the economic benefit of enterprise.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1, axletree, 2, axle sleeve, 3, wheel, 4, zerk, 5, tapered roller bearing, 6, distance cover, 7, self-aligning roller bearing, 8, socket head cap screw, 9, adjust paper washer, 10, spring washer, 11, end cap, 12, backbone sealing ring, 13, felt seal ring, 14, O RunddichtringO.
The specific embodiment
Reinforced seal 12 and the overcoat of felt seal ring 13 and tapered roller bearing 5 are installed on wheel 3; Then tapered roller bearing 5 inner rings and apart from cover 6 and self-aligning roller bearing 7, be contained on wheel 3; On 14 installations of O RunddichtringO and axle sleeve 2; Axle sleeve 2 is pressed on axletree 1; By on reinforced seal 12 and felt seal ring 13 and 9 installations of adjustment paper washer and end cap 11; By on mounted end cap 11 installations and wheel 3; Mounting spring pad 11 and socket head cap screw 8; Zerk is installed.In installation process, will add grease, and adjustment makes wheel turns flexible.
