Belt pulleys of the structural shape have popularization value.
Description
Technical field the utility model relates to a kind of quick loading and unloading belt pulley that is installed on the screw air compressor that is suitable for, and belongs to the F16H55/17 class.
Background technique is before the utility model, the belt pulley that is installed on the screw-rod air compressor generally adopts the integrated type belt pulley, very inconvenient during this belt pulley of installation or removal, need during dismounting just can pull it with La Ma or other special tool, need during installation to knock just and can put in place with sledgehammer.Mounting or dismounting very easily damage the belt pulley main wheel often, and surface fracture or integral body are broken, and cause waste, and damage air compressor screw rod main shaft and bearing seal easily simultaneously causes the screw-bearing sealing to scrap, and increases cost.
Summary of the invention task to be solved in the utility model is to provide a kind of novel structure, quick loading and unloading belt pulley easy to loading and unloading.This quick loading and unloading belt pulley is not all-in-one-piece, but split type, mainly by the awl watt and wheel hub two-part form.As long as turn during installation or removal be linked in the awl watt with wheel hub on screw or loosening screw, do not apply any external force.
For implementing the technological scheme that above-mentioned task adopts be: quick loading and unloading belt pulley branch described in the utility model is made two-part make: awl watt and wheel hub.The center portion of awl watt is processed with axis hole, and simultaneously a certain direction at axis hole is processed with keyway, and it is 1: 15～20 cone shapes that the outer surface of awl watt is processed into tapering; The awl watt outward edge and the adjacent place of inward flange of wheel hub be processed with straight shape hole, this straight shape hole is short unthreaded hole in awl watt first hole, in first hole of wheel hub is tapped hole, in this straight shape hole, be equipped with screw, it is a socket head screw, and this straight shape hole can evenly or be non-uniformly distributed on the awl watt border line.Remove this, being mutually 180 ° on the border line of awl watt, to be processed with awl watt first hole be tapped hole, first hole of the wheel hub straight shape hole for short unthreaded hole, is equipped with loosening screw in this straight shape hole.And the outer part of wheel hub still keeps zigzag fashion, be 1: 15～20 conical center hole and be processed with tapering at the core of wheel hub, and the tapering of the conical center hole of wheel hub is identical with the cylindrical taper tapering of taper hole, coincide each other.Awl watt is not an integral body simultaneously, have one surplus seam.
Adopt as above that the affected quick loading and unloading belt pulley of technological scheme is applied on the air compressor, past therewith belt pulley is compared, and its advantage is: installing/dismounting is simple, convenient, laborsaving, improves work efficiency 200% than former ordinary straps wheel.Owing to only need change wheel hub when changing belt pulley, save maintenance cost more than 50%.Avoid external force to hit simultaneously, do not contain the damage that causes main frame bearing seal and main shaft, about about 250,000 yuan/year of its direct economic benefit.
Description of drawings
Fig. 1 is the forward cross-sectional schematic of quick loading and unloading belt pulley described in the utility model, also is specification digest accompanying drawing of the present utility model.
Fig. 2 looks schematic representation for the left side of the utility model accompanying drawing 1.
Embodiment is described in further detail embodiment of the present utility model below in conjunction with accompanying drawing.
As shown in drawings, 1 is the wheel hub of quick loading and unloading belt pulley described in the utility model, and 2 are awl watt, and 3 be axis hole, and 4 be screw, and 5 be to become flexible screw, and 6 is keyway, and 7 is surplus seam.The outside of wheel hub 1 keeps its zigzag fashion, and it is 1: 15～20 taper hole that the center portion of wheel hub 1 is processed with tapering, and its internal surface keeps certain degree of finish.The center portion of awl watts 2 is processed with axis hole 3, and the internal diameter of axis hole 3 equates with the external diameter of the main shaft of air compressor, and the formation interference fit is processed with keyway 6 boring on watts 2 the interior circle, and the key on the main shaft of this keyway 6 and air compressor matches.The cylindrical taper tapering of awl watts 2 is 1: 15～20, and awl watts 2 is sleeved in the wheel hub 1.Because the outside tapering of the tapering in the center portion of wheel hub 1 and awl watts 2 is identical, taper direction is opposite, so awl watts 2 and wheel hub 1 can well coincide.Awl watts 2 is not an integral body, and leaves surplus seam 7, and wheel hub 1 and awl watt 2 closely cooperate are convenient in its width d=2～3 millimeter.Awl watts 2 is assemblied in the center portion of wheel hub 1, and the left and right plane of assembling back awl watts 2 and wheel hub 1 is on same line.At the link place of awl watts 2 with wheel hub 1, be processed with the straight shape hole of the screw that parallels with axis hole 3 center lines, this straight shape hole is short unthreaded hole in awl watt 2 first holes, and is screw hole in wheel hub 1 first hole, for the screw 4 of socket head screw is assemblied in this straight shape hole.Being equipped with the straight shape hole of screw 4 can be evenly or be not distributed on the border line of awl watts 2.During installation, to bore watts 2 earlier places on the main shaft of air compressor, make the key on the main shaft aim at the keyway 6 of boring on watt 2 interior circles, then with wheel hub 1 near awl watts 2, after aiming at screw, tighten screw 4 and make wheel hub 1 move axially and make the axle and awl watts 2 and wheel hub 1 locking of belt pulley along axis hole 3, thus fast pulley.In addition, at the place of linking of awl watts 2 and wheel hub 1 and bore on watts 2 a certain diameter line and be processed with the straight shape hole that parallels with the center line of axis hole 3, this straight shape hole is a tapped hole in awl watt 2 first holes, and be short unthreaded hole in wheel hub 1 first hole, in this straight shape hole, be equipped with loosening screw 5, before turning loosening screw 5, screw 4 is split out, to become flexible screw 5 then and place straight shape hole herein, turn loosening screw 5, wheel hub 1 is moved axially and the axle that makes belt pulley and awl watts 2 and wheel hub 1 are loosening along axis hole 3, thus loosening belt pulley, can not damage main shaft, be convenient to load and unload belt pulley.
Embodiment also is a most preferred embodiment of the present utility model as mentioned above.
