Abstract
The utility model relates to a hub reduction mechanism in engineering machinery and agricultural machinery, in particular to a steering drive axle hub reduction mechanism. The steering drive axle hub reduction mechanism comprises a steering knuckle, a hub arranged on the outer side face of the steering knuckle and sleeved with the steering knuckle, and a gear ring support arranged on the end face of the steering knuckle and connected with the steering knuckle. Due to the arrangement of the steering knuckle, the gear ring support and the hub, the hub is not connected with the gear ring support any more, and therefore stability of movement of the hub is improved, stable performance of the gear ring support is guaranteed, and moving performance of a planetary gear set is improved.
Description
Technical field
The utility model relates to a kind of construction machinery and equipment and field machine wheel hem retarding mechanism, specifically a kind of steering drive axle wheel hem retarding mechanism.
Background technology
At present, the wheel hem retarding mechanism of construction machinery and equipment, big-powered tractor steering drive axle comprises the compositions such as steering swivel, wheel hub, two bearings, gear ring support, gear ring, jam nut, pinion carrier, satellite gear.The neck of described steering swivel and gear ring support uses spline joint, with jam nut, lock, wheel hub is enclosed within the outside of steering swivel neck and gear ring support simultaneously, described two bearings are positioned at the wheelboss inner hole both sides, be that its outer ring is installed on wheel hub, one of its inner ring is arranged on gear ring and supports above, and another is arranged on steering swivel, sees Fig. 1.The connection mode of this slowing-down structure, cause two bearing inboards to connect from different parts respectively, the bad assurance of its right alignment, and the stationarity of wheel hub motion is poor, thereby affects the stability of speed reduction gearing work; In addition, because steering swivel and gear ring support, use spline joint, have free-running fit, right alignment also is difficult to guarantee, and the spline of steering swivel and screw thread process more loaded down with trivial detailsly and time-consuming, and cost is higher.
Summary of the invention
The utility model provides a kind of simple in structure in order to overcome above-mentioned defect, therefore, has improved the stationarity of wheel hub motion, has guaranteed the stability that gear ring supports, and has improved the exercise performance of compound planet gear.
The technical solution adopted in the utility model is: a kind of steering drive axle wheel hem retarding mechanism, comprise steering swivel, be arranged on steering swivel lateral surface and with the wheel hub of steering swivel suit and the end face that is arranged on steering swivel the gear ring support that is connected with steering swivel.
Owing to having designed steering swivel, gear ring, support and wheel hub, make wheel hub no longer with the gear ring support and connection, therefore improved the stationarity of wheel hub motion, guaranteed the stability that gear ring supports, improved the exercise performance of compound planet gear.
The utility model has designed, and also comprises bearing and support sleeve, and the neck of described steering swivel supports and is connected by bolt with gear ring, between steering swivel and gear ring support and bolt, is provided with support sleeve, and support sleeve is placed in the outside of bolt leading portion; Described wheel hub is placed in the outside of steering swivel neck, and bearing is arranged between wheel hub and steering swivel neck, the both sides of wheelboss inner hole.
The utility model is supported for spline joint by traditional steering swivel and gear ring, then with jam nut, lock, be improved to and be bolted, the spline and the screw thread processing that have solved steering swivel are more loaded down with trivial details and time-consuming, the technical matters that cost is higher, also avoided the spline joint gap large, right alignment is difficult to ensure the problem of card.
The accompanying drawing explanation
the structural representation that Fig. 1 is prior art in technical background.
Fig. 2 is structural representation of the present utility model.
The specific embodiment
Now by reference to the accompanying drawings the utility model is further described, Fig. 2 is a kind of embodiment of the present utility model, comprise steering swivel 1, be arranged on the lateral surface of steering swivel 1 and support 6 with the wheel hub 5 of steering swivel 1 suit and the end face that is arranged on steering swivel 1 gear ring that is connected with steering swivel 1, gear ring support 6 is for connecting the planetary gear wheels.In the present embodiment, the neck of described steering swivel 1 and gear ring support 6 and are connected by bolt 3, and gear ring supports 6 and is close proximity to the end face of steering swivel 1 neck and the bolt 3 by several even cloth settings is connected.Be provided with support sleeve between steering swivel 1 and gear ring support 6 and bolt 3, support sleeve is cylindrical shape, and the cylindrical of endoporus and bolt shank is corresponding, support sleeve is placed in the outside of bolt 3 leading portions, near that section of bolt 3 heads, support sleeve is for increasing bolt 3 intensity, prevents that bolt 3 from cutting off.Described wheel hub 5 is placed in the outside of steering swivel 1 neck, and bearing 2 is arranged between wheel hub 5 and steering swivel 1 neck, the both sides of wheel hub 5 endoporus.
The utility model, owing to having designed steering swivel 1, gear ring support 6 and wheel hub 5, makes wheel hub 5 no longer with gear ring, support 6 and is connected, and has therefore improved the stationarity of wheel hub 5 motions, has guaranteed that gear ring supports 6 stability, has improved the exercise performance of compound planet gear.It is spline joint that the utility model also supports 6 by traditional steering swivel 1 and gear ring, then with jam nut, lock, be improved to and adopt a plurality of bolts 3 to be connected, make steering swivel 1 be convenient to manufacture processing, reduce costs, solved the processing of traditional steering swivel 1 spline and screw thread more loaded down with trivial details and time-consuming, the technical matters that cost is higher; Two bearings 2 of the present utility model all be arranged on steering swivel 1 the neck outside, and wheel hub 5 between, this connection mode has solved in conventional confguration steering swivel 1 and gear ring, and to support 6 joint gaps large, right alignment is difficult to ensure the problem of card, makes the slowing-down structure assembly precision high, and work operates steadily reliable.
The utlity model has simple in structurely, assembly precision is high, characteristics easy to manufacture, that cost is low.
