Abstract
The utility model discloses a bearing for a snow plough, and belongs to bearings. The structure of the bearing for the snow plough comprises an outer ring, an inner ring and a roller, wherein the roller is arranged between the outer ring and the inner ring, and supported by a retainer; the outer ring, the inner ring and the roller are cylindrical respectively; an inner splined hole is eccentrically formed in the inner ring; and a sealing ring is arranged between the outer ring and the inner ring at the both sides of the roller. Compared with the prior art, the bearing for the snow plough disclosed by the utility model has the characteristics that the bearing has a reliable transmission torque; vibrating force is increased, so as to break the firmly-compacted ice and snow; the impact-resistant capacity of the bearing is improved, and the service life of the bearing is prolonged simultaneously; and the sealing performance of the bearing is improved, so as to prevent the grease leakage of the bearing and prevent ice and snow, and water mist from entering in the bearing. Therefore, the bearing for the snow plough has great popularization and application values.
Description
Technical field
The utility model relates to a kind of bearing, especially a kind of HLB-CX40 type snow scraper bearing.
Background technique
What snow scraper adopted usually is spiral shovel snow cutter, bearing adopts common tapered roller bearing, the principle that reason similar rotary cultivator in shovel snowfield revolves ground, so blade is major diameter continuous helical type, general diameter is between 400-600mm, blade is thin, and when rooting out the ice and snow of compacting, blade very easily damages or weares and teares.And screw blade is made complexity, and cost is high, and sharpening is difficulty also, so shovel snow cost is very high.
The tapered roller bearing sealing effect is poor, and bearing easily leaks fat, and ice and snow, water smoke easily enters bearing inside, and the impact resistance of bearing is poor, very easily damages when shoveling snow, has reduced working life, has increased cost.At present, good solution is not also arranged.
The model utility content
Technical assignment of the present utility model is to provide a kind of snow scraper bearing for above-mentioned deficiency of the prior art, and this snow scraper bearing has reliable driving torque; Increased vibration force, to break hard tightly packed ice and snow into pieces; Improve the impact resistance of bearing, improved simultaneously the working life of bearing; Improved the sealability of bearing, prevented bearing grease leakage, prevented that simultaneously ice and snow, water smoke from entering the characteristics of bearing inside.
The technological scheme that its technical problem that solves the utility model adopts is: it comprises outer ring, inner ring and roller, be provided with roller between described outer ring and inner ring, and supported by retainer, described outer ring, inner ring and roller are respectively cylindric, on described inner ring, eccentric setting has an inner splined hole, is respectively arranged with seal ring between the outer ring of described roller both sides and inner ring.
Described inner ring, outer ring and roller are respectively the high-carbon-chromium bearing steel manufacturing.
Described seal ring adopts the nitrile butadiene rubber seal ring.
The tooth top diameter of described inner splined hole is 65mm, and at the bottom of tooth, diameter is 56mm.
Described outer ring external diameter is 215mm, and width is 32mm, and described inner ring raceway external diameter is 165mm, and the offset between the central axis of described inner splined hole and the central axis of inner ring is 40mm.
Compared to the prior art snow scraper bearing of the present utility model has following outstanding beneficial effect: bearing inner race has adopted the gear transmission of internal spline cellular type, makes its reliable driving torque; Bearing adopts eccentric design, has increased vibration force, to break hard tightly packed ice and snow into pieces, produces strong up and down vibration when making bearing rotary, the ice and snow of having broken into pieces is moved by bearing rotary swing to the back, raises out or send into wagon box by snow spreader; Bearing adopts Design of Cylindrical Roller Bearing, has improved the impact resistance of bearing, the working life of having improved simultaneously bearing; Be provided with seal ring on bearing, improved the sealability of bearing, prevent bearing grease leakage, prevent that simultaneously ice and snow, water smoke from entering bearing inside; Shovel snow efficient is high, and perching knife can need not be changed for a long time, and the expense of having saved has obtained the good characteristics such as economic benefit.
Description of drawings
Accompanying drawing 1 is that the master of snow scraper bearing looks sectional view;
Accompanying drawing 2 is left TV structure schematic diagram of snow scraper bearing;
Description of reference numerals: 1, outer ring, 2, inner ring, 3, roller, 4, retainer, 5, seal ring, 6, inner splined hole.
Embodiment
Be described in detail below with reference to Figure of description 1 and 2 pairs of snow scraper bearings of the present utility model of accompanying drawing.
Snow scraper bearing of the present utility model, its structure comprises outer ring 1, inner ring 2 and roller 3, be provided with roller 3 between described outer ring 1 and inner ring 2, and supported by retainer 4, described outer ring 1, inner ring 2 and roller 3 are respectively cylindric, on described inner ring 2, eccentric setting has an inner splined hole 6, is respectively arranged with seal ring 5 between the outer ring 1 of described roller 3 both sides and inner ring 2.
Described inner ring 2, outer ring 1 and roller 3 are respectively the high-carbon-chromium bearing steel manufacturing.High tenacity requirement when using in order to satisfy bearing, Bainitic hardening technique is adopted in the inner ring 2 of bearing and outer ring 1, and quenching hardness is between 55-58HRC.Cylindrical roller adopts 25 of 15 * 20 specifications.
Described seal ring 5 adopts the nitrile butadiene rubber seal ring.Sealing configuration adopts mazy type, can prevent effectively that ice and snow and water smoke from entering.
The tooth top diameter of described inner splined hole 6 is 65mm, and at the bottom of tooth, diameter is 56mm.
Described outer ring 1 external diameter is 215mm, and width is 32mm, and described inner ring 2 raceway external diameters are 165mm, and the offset between the central axis of the central axis of described inner splined hole 6 and inner ring 2 is 40mm.
Retainer 4 adopts the grooved pressing cage, compact structure, and roller quantity is many, and intensity is high.
The snow scraper bearing is one of mechanical part important in shovel ice and snow device, and its major function is the power motor car engine, coordinates with the Inner splined hole of bearing by the spline gear on transmission shaft, is delivered to bearing inner race.Because bearing is eccentric design, by the eccentric rotary of bearing, realize power-converting is become the compound motion of vertical tremor and swing.The ice and snow shovel that is arranged on bearing means realizes breaking into pieces ice and snow and moving to rear shovel thus.
This bearing can bear larger impulsive load, and rotating speed is high, swings greatly, and the life-span is long, compact structure, the characteristics such as lightweight.
Except the described technical characteristics of specification, be the known technology of those skilled in the art.
