Abstract
The invention discloses a ball sliding pulley which comprises shaft, sheave wheel, internal-external stopping, ball, support stand, nuts, hanging ring and other components. The sheave wheel is installed on the shaft through external stopping, balls and internal stopping. One end of the shaft is fixed on left stand with shaft end nut while the other end of the shaft is fix on the right stand. The screw pole at lower end of the hanging ring goes through the hole on right and left stand upper plane and fixed with nut. The internal and external stopping, balls, and nuts are all normal universal bicycle components with a fluent and inexpensive supply. The non-standard components is easy to produce with the material requirement is low. The pulley can bear larger load while its general cost is low.
Description
Affiliated technical field
The present invention relates to hardware products, especially pulley.
Background technique
The pulley that uses generally has two kinds at present: 1, wheel directly rotates on axle, and rotational resistance is easy to wear greatly, and pulley can not carry bigger load, its low price.2, wheel rotates by the rolling bearing that is contained on the axle, and rotational resistance is little, and pulley can carry bigger load, and price is more expensive.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, a kind of ball pulley is provided, make it can reach the performance of second kind of pulley and make simple low price.
The objective of the invention is to realize as follows: ball pulley is by axle, sheave, inside and outside pan, and parts such as ball, support, nut, suspension ring are formed.Sheave is contained on the axle by outer pan, ball, interior pan, and an end of axle is with the fixing left socle of shaft end nut, spool the other end with the fixing right support of shaft end nut, the double-screw bolt of suspension ring lower end passes the hole on plane on the support of the left and right sides, fixes with nut.Used inside and outside pan, ball, the shaft end nut of ball pulley all adopts the general purpose accessory of bicycle.
The advantage that this ball pulley has is: because the general purpose accessory of inside and outside pan, ball, shaft end nut employing bicycle, so ample supply and prompt delivery, the reliable in quality price is low, and the part materials except that standard piece are few, and processing technology is simple.Therefore, ball pulley can carry bigger load, and overall cost is low.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further described.
Accompanying drawing is the erection drawing of ball pulley of the present invention.Fig. 1 is the plan view of ball pulley, and Fig. 2 is the sectional view along A-A among Fig. 1.
Among the figure 1, shaft end nut, 2, axle, 3, sheave, 4, outer pan, 5, ball, 6, interior pan, 7, right support, 8, nut, 9, left socle, 10, suspension ring.
Embodiment
With reference to accompanying drawing, ball pulley is by axle, sheave, inside and outside pan, and parts such as ball, support, nut, suspension ring are formed.Outer pan 4 is contained in the hole at sheave 3 two ends, and ball 5 is contained in the outer pan 4; Axle 2 passes the mesopore of sheave 3, and interior pan 6 is contained in the two ends of axle 2, near ball 5; One end of axle 2 fixedly left socle 9 of shaft end nut 1, it is fixing with nut 8 that the other end of axle 2 fixedly right support 7 of shaft end nut 1, the double-screw bolt of suspension ring 10 lower ends pass the hole on plane on the support of the left and right sides; By the gap that pan in rotating 6 is regulated between outer pan 4, ball 5, the interior pan 6, two axial ends nut 1 is tightened after, sheave 3 can rotate flexibly.Grease-added between outer pan 4, ball 5, the interior pan 6.Used outer pan 4, ball 5, interior pan 6, the shaft end nut 1 of ball pulley all adopts the general purpose accessory of bicycle.The screw thread identical with interior pan 6 adopted at axle 2 two ends.Suspension ring 10 are available standards part lifting bolt also, and support can be made with general steel sheet.Simple with this ball pulley manufacturing process, overall cost is low.
