Description
Technical field
The utility model belongs to annular gear structure technical field, specifically, relates to a kind of ring gear holder combination.
Background technique
At present, ring gear and the gear ring support device of heavy truck wheel reductor are split type, ring gear has jump-ring slot, short external tooth is processed with in the outer end of gear ring support, gear ring support is coordinated by short external tooth with ring gear, after ring gear support and ring gear are assembled together, jump ring are put in jump-ring slot and then jump ring are fixedly connected, the connecting mode of this ring gear and ring gear support.Due to ring gear having jump-ring slot, groove is opened on internal tooth, therefore weakens the intensity of gear, easily causes ring gear to rupture, and the load capacity of heavy truck itself is very large, more easily causes spring tooth, or is broken by tooth, thus cause the damage of gear ring support; In addition, the processing request of this assembling mode to jump-ring slot is higher, and easily becomes insecure; 3rd, compare during assembling and waste time and energy, when assembling bad, jump ring will be scrapped.The wasting of resources is relatively more serious, improves production and maintenance cost.
Model utility content
For solving above technical problem, the purpose of this utility model is to provide a kind of ring gear holder combination, intensity is high, and load-carrying ability is strong, and gear ring support need not process short external tooth, ring gear is without machining clamp spring slot, gear ring support and ring gear do not use jump ring to assemble yet, and stability is high, decrease manufacturing procedure, assembly process and saving material, save resource, reduce cost.
The utility model object is achieved in that a kind of ring gear holder combination, its key is: comprise ring gear and gear ring support, one end of described ring gear is docked with the bigger diameter end of described gear ring support, this ring gear and described gear ring support one-body molded, and the medial axis of ring gear and gear ring support overlaps completely.
Adopt said structure, in ring gear holder combination, ring gear is connected with planet wheel, and the miner diameter end of gear ring support is connected with vehicle bridge, and integrated ring gear and gear ring support, its intensity is high, load-carrying ability is strong, and gear ring support need not process short external tooth, and gear ring support and ring gear also need not use jump ring to assemble, stability is high, decrease manufacturing procedure and material, saved resource, reduced cost.Integrative-structure can by extruded, and ring gear holder combination ensure that the medial axis of ring gear and gear ring support overlaps completely, can not cause eccentric rotary between ring gear and gear ring support, reduce frictional loss because of assembly error.
Above-mentioned ring gear inwall is provided with the support platform of internal tooth and hoop, and described support platform is near described gear ring support.
Adopt said structure, the internal tooth of ring gear is only connected with planet wheel, need not coordinate with gear ring support again, can reduce the design length of internal tooth like this, has saved cost of material, and support platform is used for effect that is spacing and location.
The bigger diameter end end face of above-mentioned gear ring support is evenly provided with oil-through hole and mounting hole.
Adopt said structure, by oil-through hole circulation lubricant oil, easily and effectively, disassemble whole ring gear holder combination by mounting hole.
The diameter of above-mentioned oil-through hole is 19.9 ~ 20.3mm, and the model of described mounting hole is M10.
Adopt said structure, the intensity of the whole ring gear holder combination of the excessive impact of mounting hole, mounting hole is too small, is unfavorable for installing.
The path intersegmental part of above-mentioned gear ring support is provided with shoulder hole and spline, and described spline is positioned at the bigger diameter end side of gear ring support, and described shoulder hole is positioned at the miner diameter end side of described gear ring support, and the outer wall of described gear ring support path section is provided with step.
Be provided with the support rim of hoop between above-mentioned shoulder hole and spline, described spline is provided with the positioning table of hoop near ring gear one end.
Adopt said structure, support rim and positioning table all play spacing, location, and shoulder hole, spline, support rim and the combination of positioning table are convenient to ring gear holder combination and are connected with vehicle bridge.
The outside diameter of above-mentioned ring gear and gear ring support bigger diameter end is 262 ± 0.1mm, and the interior circular diameter of this ring gear and gear ring support bigger diameter end is 245.5mm.
Adopt said structure, the ring gear holder combination of this size, use extensively, be beneficial to production.
Beneficial effect:
A kind of ring gear holder combination of the utility model, intensity is high, and load-carrying ability is strong, and gear ring support need not process short external tooth, and gear ring support and ring gear do not use jump ring to assemble yet, and stability is high, decreases manufacturing procedure and material, has saved resource, has reduced cost.
