Abstract

The utility model relates to mine car wheels. The internal hole of the wheel body 1 is a through hole, the internal part of which uses a 310KA-model single row radial ball bearing 5 and a 310 KA-model single row radial ball bearing 6; one of the internal ring and the external ring of the bearing is positioned with a shaft, a spring retaining ring 4, and a convex shoulder, and the other ring is positioned with a shaft shoulder and a hole, a spring retaining ring 10, and a liner 9, and a spacing sleeve 3 and an oil ring 2 are divided between the two bearings. One end of the wheel is enclosed, and the other end of the wheel is sealed with the sealing ring 7 of the framework, and the sealing ring 7 is arranged between the bearing 6 and the liner 9. The mine car wheels of the utility model can effectively solve the technical problems that the wheels can be thrown and the sealing is not tight in a more adverse environment.

Description

Tramcar wheel

Affiliated technical field

The utility model relates to a kind of mine transportation equipment, specifically, relates to a kind of tramcar wheel.

Background technology

1 ton of mine car is the main transportation device in mine, and the tramcar wheel of having continued to use decades is for offsetting the axial forces that mine car produces because of track injustice, bend more in operational process, and every wheel uses two 7310 tapered roller bearings; The wheel body endoporus is provided with step, and two bearings are separated; Wheel is sealed at both ends to adopt gland and labyrinth seal radially respectively.

Because tramcar wheel step endoporus needs the processing of secondary clamping, thereby two bearings hole right alignment is difficult for guaranteeing.Two bearings hole right alignment is poor, and is very big to the tapered roller bearing influence, and rolling body contacts modified line with inside and outside circle and is the some contact, and stressed back cage ring rapid wear causes frame, and wheel throws away, and safety is produced, threatened in influence.Gland links with screw and wheel body, often comes off, breaks in transporting the coal process or stolen, causes water and coal slime to be irritated in the bearing body, and wheel can not use.The wheel other end is labyrinth seal radially, lacks flexibility and regulatory function, water and coal slime often occur along the phenomenon that the gap of axle and seal ring enters bearing bore, causes lubricating grease rotten, increases the wearing and tearing of bearing, reduces the service life of bearing.

Summary of the invention

The purpose of this utility model is to provide a kind of can effectively solve the wheel problem of getting rid of, good airproof performance, the tramcar wheel that cost is low.

The technical scheme that its technical matters that solves the utility model adopts is: the endoporus of wheel body is a through hole, use two 310KA type single-row radial ball bearings in the through hole, one on the inside and outside circle of bearing with axle with trip ring and convex shoulder location, another is located with the shaft shoulder and internal circlip, lining, separates with spacer and oil ring between the two bearings; The sealing of wheel one end, the other end seals with the seal ring of band skeleton, and seal ring is arranged between bearing and the lining.

Because the wheel body endoporus is a through hole, thereby has guaranteed the right alignment of two bearings, efficiently solves the wheel problem of getting rid of; Wheel one end sealing, the elastic skeleton of other end seal ring be the wearing and tearing of compensation sealing circle and axle at any time, thereby make the wheel long term seal good; In addition, bearing is changed into more cheap common single-row radial ball bearing, the whole cost of wheel is descended.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the existing tramcar wheel scheme drawing of using.

Fig. 2 is the structure principle chart of the utility model tramcar wheel.

The specific embodiment

The endoporus of wheel body 1 is a through hole, use two 310KA type single-row radial ball bearings 5,6 in the through hole, one on the inside and outside circle of bearing with axle with trip ring 4 and convex shoulder location, another is located with the shaft shoulder and internal circlip 10, lining 9, separate with spacer 3 and oil ring 2 between the two bearings 5,6, experimental results show that this structure can effectively solve the axial force problem in the mine car operational process.Simultaneously because the wheel body endoporus is a through hole, separate the method for bearing with spacer 3 and the former step of oil ring 2 replacements, make the wheel can a clamping, can finish whole manufacturing procedures, improved working accuracy and efficient, guaranteed the right alignment of two bearings.After 7310 bearing spacers damaged, rolling body came off, and bearing becomes two bodies by one, and 310KA bearing 5,6 rollers are in trajectory, and the bearing two ends are blocked by plastic seal ring, and Internal and external cycle can't separate, thereby efficiently solves the wheel problem of getting rid of.The sealing of wheel one end, the other end adopts the hermetically-sealed construction of monomer hydraulic support, promptly uses oil resistant, seal ring wear-resisting, the band skeleton to seal, and seal ring 7 is arranged between bearing 6 and the lining 9.Because wheel one end sealing, reduced packing less link, the seal ring 7 of other end band elastic skeleton tightly is pressed on the axle 8, as rubber ring and axle wearing and tearing are arranged, then elastic skeleton can compensate, thereby make the wheel long term seal good, solved tramcar wheel long-time running poorly sealed technical barrier in, prolonged period of inspection and repair and tramcar wheel service life than rugged environment.The location employing circlip of the utility model bearing changes existing method of locating with throttled nut with tramcar wheel, and every wheel shaft can shorten 150mm like this, reduces by two nuts, and axle is not wanted the car silk yet; Except that wheel body 1, spacer 3, oil ring 2, all the other are all gauge member, have simplified structure from face, have reduced work programme, in addition, bearing are changed into more cheap common single-row radial ball bearing, and the whole cost of wheel is descended.Now right with tramcar wheel, about 700 yuan of the every pair of need, the utility model wheel only needs 500 yuan to every pair.

Now cooperating with the hole with the tramcar wheel housing washer is transition fit, and Kong Youyi ear platform, and the outer ring of two bearings is separated, when therefore removing two bearing shells of same axle head, need can to utilize the machinery dismounting with after 180 ° of the hub upsets, so it is big to keep in repair labour intensity, operating efficiency is low.The utility model tramcar wheel is easy to assembly and disassembly, can effectively utilize mechanical equipment to load and unload, and suitable operating line carries out mine car to be repaired, and not only alleviates workman's manual labor, raises the efficiency, and has improved assembly precision and reduced the damage of components that dismounting causes.Its sequence of erection is: install internal circlip 10 → lining 9 → seal ring 7 → bearing 6 → spacer 3, oil ring 2 → bearing 5 → axle with trip ring 4 → with hydraulic compressor spools 8 pack into wheel interior → tighten internal circlip 10 → injection sodium base butter.

The utility model tramcar wheel structural principle also is applicable to 3 tons of mine cars, stores van, flat truck, the askew car of drop-bottom car in mine etc., and the above vehicle of all use the utility model tramcar wheel structural principles all belongs to the row of the utility model protection.
