Abstract
The invention relates to a detachable transmission shaft type wheel. A width plate is internally provided with a shaft sleeve in a welding way, a left shaft and a right shaft are respectively connected with the shaft sleeve in transition fit, one end of the connection part of the left shaft and the width plate and one end of the connection plate of the right shaft and the width plate are provided with flange plates, the flange plates are respectively in an integral structure with the left shaft and the right shaft, and the flange plates are connected with the width plate through bolts. According to the detachable transmission shaft type wheel provided by the invention, the left shaft and the right shaft are connected with the width plate by the flange plates and the bolts, so that the original integral car shaft is divided into a two-section (left shaft and right shaft) type structure so as to avoid the problem that the entire wheel is required to be exchanged when one end of the car shaft is broken due to the long time use. The car shaft is manufactured by forging and tempering carbon alloy steel, and thus the intensity is high, the service life is long, and the welding can be avoided. The left shaft and the right shaft of the detachable transmission shaft type wheel are respectively connected with the shaft sleeve in the transition fit, and the flange plates, the bolts and the width plate are in the split type structure, and thus the detachable transmission shaft type wheel can avoid the problem that in the original integral structure of the car shaft and the width plate or the shaft sleeve, the entire wheel is scraped because of the non-detachability of the car shaft when one end of the car shaft is damaged.
Description
Technical field:
The present invention relates to a kind of harbour planer-type container crane wheel, particularly a kind of detachable transmission shaft type wheel.
Background technology:
As shown in Figure 1; Existing harbour planer-type container crane wheel is connected through welding by former a and axletree b and forms; Former a material adopts low alloy steel plate; Axletree b adopts medium carbon alloy steel through forging and modified, and low alloy steel plate has good welding performance, and medium carbon alloy steel should not weld owing to carbon content is higher; Medium carbon alloy steel when welding will with wlding welding at high temperature; The metallographic structure of medium carbon alloy steel at high temperature alters a great deal; Weld becoming from molten form rapidly is solid-state after having welded, and welding fusion position produces very big stress when quick cooling, and welding stress can not be well eliminated in the insulation of postwelding; The welding fusion position metallographic structure of axletree b is loose, has tiny between wlding and the axletree b and the crackle generation; Because the wheel frequency of utilization is high, load-carrying is big, and wheel shaft is usually ruptured in the weld of former a and axletree b by the reverse stress effect for a long time, and the service life of this wheel is shorter, the just some months that has, and long just ruptures more than a year, causes wheel to scrap.
For improving this situation, people have made improvement to existing wheel, and are as shown in Figure 2; The welding that wheel has been cancelled between axletree c and the former d connects; In wheel, increased an axle sleeve e, axle sleeve e connects with former d welding, and axle sleeve e is worked into the size littler than axletree c; Heat wheel again; When wheel axle sleeve e is heated to when bigger than axletree c diameter axletree c is put into axle sleeve e, wait the wheel temperature fall to get off the back, make axletree c and wheel be unified into an integral body because axle sleeve e metallo-shrinks that axletree c is held tightly; Comparing original wheel the service life of this wheel will grow, but in use when when fracture takes place for axletree c and axle sleeve e point of attachment, can't dismantle, with causing scrapping of whole wheel.
Summary of the invention:
The object of the present invention is to provide a kind of long service life, easy accessibility, detachable transmission shaft type wheel that intensity is high.
To achieve these goals, the present invention proposes following technical scheme realization:
Detachable transmission shaft type wheel is made up of left side axle, right axle, former, axle sleeve, flange; It is characterized in that: be welded with axle sleeve in the former; Left side axle, right axle adopt transition fit to be connected respectively with shaft room; Left side axle, right axle are provided with flange with former junction one end respectively, and flange is an integral structure with left side axle, right axle, and flange is connected with former through bolt.
The soluble technical matters of the present invention is:
(1) patent of the present invention is through being welded with axle sleeve in the former; Adopt transition fit to be connected respectively with shaft room on left side axle, right axle; Left side axle, right axle also are connected with former through flange, bolt, and original integral type axletree is divided into left side axle and right side axle two sectional type structure, have avoided original wheel to adopt an axletree; When the fracture of the long-time use of axletree one end, cause whole wheel to change; And axletree adopts medium carbon alloy steel through forging and modified manufacturing, and intensity is high, the life-span is long, has avoided welding.
(2) patent of the present invention adopts left and right axle to adopt transition fit to be connected respectively with shaft room; And this split type connection structure through flange, bolt and former; Avoided original axletree and former or axle sleeve to connect as one the formula structure; When an end axletree damages, can't dismantle because of axletree and to cause whole wheel to scrap cost-cutting.
Description of drawings:
Fig. 1 is existing car wheel structure figure;
Fig. 2 is the car wheel structure figure after improving;
Fig. 3 is a front view of the present invention;
Fig. 4 is a left view of the present invention;
Fig. 5 is the A-A cutaway view of left view of the present invention.
The specific embodiment:
Like Fig. 3, Fig. 4, shown in Figure 5, detachable transmission shaft type wheel is made up of left side axle 1, right axle 2, former 3, axle sleeve 4, flange 5; Be welded with axle sleeve 4 in the former 3; Left side axle 1, right axle 2 adopt transition fit to be connected respectively with 4 on axle sleeve; Left side axle 1, right axle 2 are provided with flange 5 with former 3 junctions one end respectively, and flange 5 is an integral structure with left side axle 1, right axle 2, and flange 5 is connected with former 3 through bolt.When work; Because flange 5 is connected with former 3 through bolt; The bolt pretension produces friction; And flange 5 is connected as a single entity with left side axle 1, right axle 2 respectively, and therefore the moment of torsion between left side axle 1, right axle 2 and the wheel body can transmit through the friction between flange 5 and the former 3, thereby makes left side axle 1, right axle 2 drive wheel body and rotate.
This patent has long service life, easy accessibility, intensity advantages of higher, has great promotional value.
