Abstract
The utility model discloses a spinning pulley with a key, and belongs to the technical field of transmission devices. The spinning pulley with the key is composed of a V-shaped large pulley, a shaft sleeve, a V-shaped small pulley and the key. The key integrally formed with the shaft sleeve is arranged on the right side of the shaft sleeve, and the V-shaped large pulley and the V-shaped small pulley are welded to the two sides of the shaft sleeve respectively. After the improvement, the spinning pulley with the key has the advantages of being simple in processing technique, high in production efficiency, low in processing cost and high in product assembly efficiency, saving materials and the like, can be widely applied to agricultural machinery and is wide in market prospect.
Description
Technical field
The utility model belongs to transmission device technical field, is particularly related to a kind of spinning belt pulley that carries key.
Background technique
As shown in Figure 3, the transmission pulley being connected with axle sleeve that agricultural mechanical field is common, mostly adopts at Pulley shaft and puts processing keyway, a more equipped key is on axle sleeve, in order to same transmission shaft, connects.The processing cost of this kind of product is high, and efficiency of assembling is low, and require this axle sleeve is through hole simultaneously, in order to process keyway, requires axle sleeve external diameter larger, thereby has increased energy consumption.Because product left end is provided with the transmission shaft that a bolt coordinates in order to fixing coaxial cover, need on axle sleeve, increase a sprue, and weld with sprue at three apertures of axle sleeve circumference punching.This transmission pulley complex manufacturing, after welding, product strength weakens, and reduce working life, and appearance effect is poor.
Model utility content
The purpose of this utility model is to overcome the above-mentioned defect of mentioning and deficiency, and a kind of spinning belt pulley that carries key is provided.
The technological scheme that the utility model is realized its object employing is as follows.
Carry a spinning belt pulley for key, V groove big belt pulley, axle sleeve, V groove small belt pulley and key, consist of, be arranged at axle sleeve right side with the integrated key of axle sleeve, described V groove big belt pulley and V groove small belt pulley are welded in respectively axle sleeve both sides.
Described axle sleeve left side is provided with bolt hole, and right side is provided with the macropore with bolt hole coaxial cooperation.
The described height by the compressing key of macropore pipe wall material indent is 20-24mm, and width is 6.0-6.5mm.
The height of described key is 22mm, and width is 6.3mm.
The V groove big belt pulley of rotary press modelling is provided with LC hole and aperture, and the V groove small belt pulley of rotary press modelling is provided with right center hole, described LC hole and right center hole concentric.
After improvement, with the spinning belt pulley of keyway, have that processing technology is simple, manufacturing efficiency is high, processing cost is low, material is saved, Product Assembly efficiency high, thereby the utility model product will be widely used in, on farm machinery, having wide market prospects.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Carry a spinning belt pulley for key, V groove big belt pulley 1, axle sleeve 2, V groove small belt pulley 3 and key 4, consist of, be arranged at axle sleeve 2 right sides with the integrated key 4 of axle sleeve 2, described V groove big belt pulley 1 and V groove small belt pulley 3 are welded in respectively axle sleeve 2 both sides.
Described axle sleeve 2 left sides are bolt hole 2a, and right side is the macropore 2b with bolt hole 2a coaxial cooperation.As preferably, the described height by the compressing key 4 of macropore 2b pipe wall material indent is 20-24mm, and width is 6.0-6.5mm.As more preferably, the height of described key 4 is 22mm, and width is 6.3mm.
The V groove big belt pulley 1 of rotary press modelling is provided with LC hole 1a and aperture 1b, and the V groove small belt pulley 3 of rotary press modelling is provided with right center hole 3a, described LC hole 1a and right center hole 3a concentric.
The Seiko machine shaping on lathe of the blank round steel of axle sleeve 2 obtains key 4 by the recessed compacting of self material on punch press.Again axle sleeve 2 is obtained to spinning belt pulley integral body with V groove big belt pulley 1,3 welding of V groove small belt pulley successively.
The utility model is illustrated according to embodiment, is not departing under the prerequisite of present principles, and this device can also be made some distortion and improvement.It should be pointed out that all employings are equal to the technological scheme that the modes such as replacement or equivalent transformation obtain, and all drop in protection domain of the present utility model.
