Abstract
The utility model relates to a rear drive axle slewing and swing device of a carry-scraper and a loader, and the rear drive axle slewing and swing device can simultaneously bear large axial force, large radial force and large overturning moment. A rear axle swing frame is respectively connected with slewing bearing outer ring bolts on the two sides through connecting rings on the two sides, slewing bearing inner rings on the two sides are respectively connected with a rear support or a front support through bolts, and the rear support and the front support are respectively connected with a rear rack through bolts. The rear axle swing frame installed with a slewing bearing is adopted, simultaneous touchdown of four wheels on the two sides of a front axle and the two sides of a rear axle is ensured under rugged road conditions, adhesive force and adhesive weight of the wheels of a whole machine are used fully, and traction of the whole machine is increased. The slewing bearing can simultaneously bear the large axial force, the large radial force and the large overturning moment, stress conditions of a single hinged middle point of an original lever-type swinging fork are improved, faults such as deformation, fracture and unstability of the swinging fork are avoided, reliability and availability in a running and operation process of equipment are ensured, the faults are reduced, production efficiency is improved, and cost is reduced.
Description
Technical field
The utility model relates to a kind of scoper and loader rear driving axle rotary oscillation device.
Background technology
Ground surface works loader and underground mine scoper are formed by horizontally hinged mutually forebay and afer bay, front driving axle is captiveed joint with forebay, rear driving axle is rotationally connected by back axle swing span and afer bay, can land simultaneously under rough road conditions in order to guarantee four wheels of propons and back axle both sides.Point articulated lever served as the back axle swing span and is connected with rear driving axle during existing ground surface works loader and underground mine scoper afer bay adopted, and this is applicable to little type.Big-and-middle-sized ground surface works loader and underground mine scoper bear larger axis simultaneously to power, diametral load and tilting moment, and the back axle swing span adopts the structure of mid point hinged lever to be difficult to bear above-mentioned significant load, causes faults such as lever distortion, fracture, unstability.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of scoper and loader rear driving axle rotary oscillation device, and it can bear larger axis simultaneously to power, diametral load and tilting moment.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of scoper and loader rear driving axle rotary oscillation device comprise afer bay and the back axle swing span that rear driving axle is installed; The back axle swing span is connected with the pivoting support outer ring bolt of both sides respectively by the clamping ring of both sides, and the pivoting support inner ring of both sides is connected with after poppet or front frame by bolt respectively, and after poppet is connected with the afer bay bolt respectively with front frame.Described pivoting support outer ring is equipped with lubricating nipple.Can bear larger axis simultaneously to the pivoting support of power, diametral load and tilting moment, can be by mechanical industry standard JB/T2300-2011 customization and the supply of material.
The beneficial effects of the utility model are:
1. the utility model adopts the back axle swing span that pivoting support is installed, and guarantees that four wheels of propons and back axle both sides can land under rough road conditions simultaneously, improves the adhesive ability of wheel, takes full advantage of the weight of sticking together of complete machine, increases the tractive force of complete machine; Guarantee stability, crossing ability and the full output of complete machine simultaneously.
2. pivoting support can bear larger axis simultaneously to power, diametral load and tilting moment, guarantee reliability, the serviceability rate of equipment when ground surface works loader and underground mine scoper, particularly big-and-middle type turn round operation, reduce breakdown of equipment and can enhance productivity, reduce operating cost greatly.
3. pivoting support is antifriction-bearing box, than the slide hinged lever of original employing mid point, ensuring smooth transmission, efficient height.
4. pivoting support is by mechanical industry standard JB/T2300-2011 customization and the supply of material, and reliable in quality, cost are lower.
5. the utility model adopts the after poppet that pivoting support is housed to be connected with the afer bay bolt respectively with front frame, and stress condition rational in infrastructure, as to have improved the single hinged mid point of original lever swing fork has been avoided faults such as swing fork distortion, fracture, unstability.
6. parts of the present utility model all adopt bolt to connect, and have avoided welding deformation and welding residual stress, have improved reliability, serviceability rate and the service life of whole device greatly.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the birds-eye view of Fig. 1.
The specific embodiment
Embodiment 1As shown in Figure 1: a kind of scoper and loader rear driving axle rotary oscillation device comprise afer bay and the back axle swing span 5 that rear driving axle 6 is installed; Back axle swing span 5 is connected with pivoting support outer ring 3 bolts of both sides respectively by the clamping ring 4 of both sides, and the pivoting support inner ring 2 of both sides is connected with after poppet 1 or front frame 7 by bolt respectively, and after poppet 1 is connected with the afer bay bolt respectively with front frame 7.Pivoting support outer ring 3 is equipped with lubricating nipple 8, can be to the pivoting support grease up.
Adopt by pivoting support reliable in quality, the cost of mechanical industry standard JB/T2300-2011 customization and the supply of material lower.Model is: 010.20.250.10 JB/T 2300.
Employing is equipped with the back axle swing span of pivoting support, guarantees that four wheels of propons and back axle both sides can land under rough road conditions simultaneously, improves the adhesive ability of wheel, takes full advantage of the weight of sticking together of complete machine, increases the tractive force of complete machine; Guarantee stability, crossing ability and the full output of complete machine simultaneously.The utility model adopts the after poppet that pivoting support is housed to be connected with the afer bay bolt respectively with front frame, and stress condition rational in infrastructure, as to have improved the single hinged mid point of original lever swing fork has been avoided faults such as swing fork distortion, fracture, unstability.
