Abstract
The utility model discloses an aluminum alloy nylon engineering mechanical pulley which consists of a nylon pulley and a cylinder aluminum alloy inner cover embedded in the inner circle of the nylon pulley. The inner wall of the aluminum alloy inner cover is provided with an oil groove with one circle around the wall and two symmetrical oil grooves at the vertical direction. The utility model overcomes the defect of high temperature and deformation of the original nylon engineering mechanical pulley.
Description
Described technical field
The utility model belongs to machinery pulley, especially a kind of improved engineering machinery nylon pulley.
Background technique
Existing engineering machinery pulley is no bearing pulley as crane with pulley, tower crane pulley, mainly adopts the accurate casting of engineering plastic nylon to form, and the shortcoming of this kind pulley is directly to contact with the pulley inner ring at axle, because of frictional force is big, and easily temperature distortion.
Summary of the invention
The purpose of this utility model provides a kind of improved engineering machinery nylon pulley, has overcome original technology yielding shortcoming of being heated.
The utility model is realized with following technological scheme: overlap in the inner ring of nylon pulley embeds a cylindrical shape aluminum alloy, have together the symmetrically arranged groove of groove and vertical direction two roads around circumference in this aluminum alloy on the inner ring wall of cover as oil groove.
Owing to adopt technique scheme, make to the utlity model has good, the high temperature resistant on-deformable advantage of wear-resisting property.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is a sectional view of the present utility model.
Fig. 1-the 1st, the partial sectional view of Fig. 1.
Fig. 2 is the structural representation of cover in the aluminum alloy.
Fig. 2-the 1st, the worm's eye view of Fig. 2.
Among the figure, 1. nylon pulley 2. overlaps in the aluminum alloy.3,4. oil groove, 5. around circumferential groove, 6. vertical groove.
Embodiment
In Fig. 1, cover (2) is embedded in the inner ring of nylon pulley (1) in the cylindrical shape aluminum alloy, has on the inner ring of cover (2) in aluminum alloy around the wall groove in one week (4) and the symmetrically arranged groove of vertical direction (3) as oil groove.In the present embodiment, in order to make cover (2) and nylon pulley (1) strong bonded in the aluminum alloy, in aluminum alloy, have 4 road grooves (6) of vertical direction symmetry on the periphery wall of cover (2), around the 2 road grooves (5) in one week of wall.In actual production, cover (2) and nylon pulley (1) in the aluminum alloy are cast into one.
Claims (2)
1, a kind of nylon aluminum alloy engineering machinery pulley, it is characterized in that overlapping in the cylindrical shape aluminum alloy by nylon pulley and embedding nylon pulley inner ring and form, have oil groove and the vertical direction two roads symmetrically arranged oil groove of substantially horizontal on the inwall that in aluminum alloy, overlaps around one week of wall.
2, aluminum alloy engineering machinery pulley according to claim 1 has vertically symmetrically arranged grooves in four roads (6) and the twice groove (5) around circumference on the periphery wall that it is characterized in that overlapping in aluminum alloy.
