Abstract
The utility model discloses a high and durable pulley of bearing nature, including spoke and axle sleeve, the inside wall of spoke leaves the centrum with spoke integrated into one piece, the both sides of centrum are passed through to fill the welding medium and are constituted overall structure with the axle sleeve, and the inner wall of this pulley adoption spoke leaves the structure of centrum, forms the groove, through filling welding medium and shaft liner connection, avoids appearing the lack of penetration condition and takes place, just is difficult for forming in the welding seam and presss from both sides the sediment, avoids the pulley under long -term use, causes stress concentration, forms the crack, and welded structure is complete for this pulley, and bearing nature is great, and long service life.
Description
Technical field
The utility model relates to pulley technical field, is specially the pulley that a kind of bearing is high and durable.
Background technique
Pulley is the circle wheel that can rotate around central shaft.At the circumferential surface of circle wheel, there is groove, rope is wound in groove, the firmly either end at rope for traction two ends, then rope and circle take turns between frictional force can impel to justify and take turns and rotate around central shaft, tradition large pulley is the structure of spoke welding axle sleeve, but the welded structure of pulley is surface soldered mostly, fusion penetration degree is inadequate, and exist for the situation of through welding, under long-term use, stress is concentrated, the gap of existence is expanded gradually, until produce obvious naked eyes visible crack, cause pulley fatigue failure, for this reason, we propose the high and durable pulley of a kind of bearing.
Model utility content
The purpose of this utility model is the pulley providing a kind of bearing high and durable, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technological scheme: the pulley that a kind of bearing is high and durable, comprise spoke and axle sleeve, the madial wall of described spoke leaves the integrated centrum with spoke, and the both sides of described centrum form overall structure by filling welding medium and axle sleeve.
Preferably, described centrum is isoceles triangle shape centrum.
Preferably, described centrum is right angle trigonometry shape centrum.
Preferably, madial wall and the axle sleeve outer side wall of described spoke leave centrum, and centrum is isoceles triangle shape centrum.
Compared with prior art, the beneficial effects of the utility model are: this pulley adopts the inwall of spoke to leave the structure of centrum, forms groove, are connected with axle sleeve by filling welding medium, avoid occurring that lack of penetration situation occurs, and not easily in weld seam, form slag inclusion, avoid pulley under long-term use, cause stress to concentrate, form crack, this pulley welded structure is complete, and bearing is comparatively large, and long service life.
Accompanying drawing explanation
Fig. 1 is the first example structure schematic diagram of the utility model;
Fig. 2 is the utility model the second example structure schematic diagram;
Fig. 3 is the third example structure schematic diagram of the utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment one:
Refer to Fig. 1, the utility model provides a kind of technological scheme: the pulley that a kind of bearing is high and durable, comprise spoke 1 and axle sleeve 2, the madial wall of described spoke 1 leaves the integrated centrum 4 with spoke 1, the both sides of described centrum 4 form overall structure by filling welding medium 3 with axle sleeve 2, the inwall of spoke 1 leaves the structure of isoceles triangle shape centrum, form groove, be connected with axle sleeve 2 by filling welding medium 3, avoid occurring that lack of penetration situation occurs, and not easily in weld seam, form slag inclusion, avoid pulley under long-term use, stress is caused to concentrate, form crack, this pulley welded structure is complete, bearing is larger, and long service life.
Embodiment two:
Refer to Fig. 2, the utility model provides another kind of centrum to be: described centrum 4 is right angle trigonometry shape centrum, and the inwall of spoke 1 leaves the structure of right angle trigonometry shape centrum 5, form groove, being connected with axle sleeve 2 by filling welding medium 3, avoiding occurring that lack of penetration situation occurs, and not easily in weld seam, forming slag inclusion, avoid pulley under long-term use, cause stress to concentrate, form crack, this pulley welded structure is complete, bearing is comparatively large, and long service life.
Embodiment three:
Refer to Fig. 3, the utility model provides another kind of centrum to be: madial wall and axle sleeve 2 outer side wall of described spoke 1 leave centrum 4, and centrum 4 is isoceles triangle shape centrum, the madial wall of spoke 1 and the outer side wall of axle sleeve 2 all leave isoceles triangle shape vertebral body structure, form groove, be connected with axle sleeve 2 by filling welding medium 3, avoid occurring that lack of penetration situation occurs, and not easily in weld seam, form slag inclusion, avoid pulley under long-term use, cause stress to concentrate, form crack, this pulley welded structure is complete, and bearing is comparatively large, and long service life.
Although illustrate and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments when not departing from principle of the present utility model and spirit, scope of the present utility model is by claims and equivalents thereof.
