Description
Technical field
The present invention relates to a kind of sun wheel planet carrier structure, is the sun wheel planet carrier structure that a kind of incomplete teeth-type connects specifically.
Background technique
Sun gear is connected with planet carrier in the existing planet carrier structure, sun gear is made two tooth portions usually, in the middle of two tooth portions, leave enough distances as tool withdrawal groove, the diameter of tool withdrawal groove is subjected to the tooth root parameter restriction of two tooth portions, the diameter of tool withdrawal groove can not be greater than root circle, so tool withdrawal groove diameter easy-rupturing less than normal, bulk strength is affected; Two tooth portions are owing to be two different tooth portions, and a tooth portion requires gear hobbing-carburizing-quenching-roll flute, and another tooth portion requires first gear shaping, two tooth portion amount of deformation differ after the heat treatment, can't whole roll flute, influence transmission accuracy and noise, processing technology is also very complicated, the manufacture cost height.
The claimant is 20082004972.3 high-efficiency energy-saving hoist gear change device for vessel in the patent No. of first to file, adopting external diameter is the sun gear of an elongated tooth portion, the jump ring groove at solar wheeling tooth portion one end and two intervals of processing, planet carrier internal gear engagement place, sun gear had not only been done gear transmission but also had made coupling to connect with planet carrier, drive path is short, and its deficiency is: have the jump ring groove in the middle of the sun gear, produce stress at jump ring groove place and concentrate, the sun gear easy-rupturing, working life is short; Planet carrier and sun gear be mainly by jump ring location in the jump ring groove at two intervals, and in the process that working environment changes, the chucking between two jump rings is easily loosening even come off, and has a strong impact on usability, has potential safety hazard.
Summary of the invention
For the processing technology complexity, manufacture cost height, the transmission accuracy that solve in the prior art in the planetary pinion transmission on the same sun gear two different tooth portions low, and have tool withdrawal groove in the middle of the sun gear or jump ring groove stress is concentrated, the sun gear easy-rupturing, deficiencies such as usage safety performance is low, the life-span is short, the purpose of this invention is to provide a kind of simple in structure, easy to process, low cost of manufacture, sun gear stress be can effectively reduce, Safety performance and a kind of incomplete teeth-type sun wheel planet carrier structure in working life improved.
The technical solution used in the present invention is: a kind of incomplete teeth-type sun wheel planet carrier structure, mainly comprise sun gear, planet carrier and planet wheel, the external diameter of sun gear is elongated outer toothed portion, planet carrier is installed on the sun gear external diameter, planet carrier connects planet wheel through planet axis by bearing, its technical characterstic is that elongated outer toothed portion one end of described sun gear external diameter is provided with incomplete outer toothed portion, the internal tooth of planet carrier is an incomplete internal tooth portion, and the incomplete internal tooth portion of described planet carrier is engaged in the incomplete outer toothed portion.
Further, the former top circle d01-k * Mn of the top circle d1=of the incomplete outer toothed portion of described sun gear, when processing incomplete outer toothed portion, roll earlier and process elongated outer toothed portion, the other end car in outer toothed portion removes part tooth top k * Mn then, and the top circle d1 that processes incomplete outer toothed portion forms a positioning step; The former root circle d02-k * Mn of the incomplete internal tooth root circle d2=of portion of described planet carrier, the incomplete internal tooth of the top circle d1=root circle d2 of portion of incomplete outer toothed portion, when processing incomplete internal tooth portion, the part profile of tooth is only cut out by line cutting internal tooth portion, leaving part tooth top k * Mn does not process, wherein k is incomplete tooth factor, and Mn is a modulus.
Again further, the outer end of the incomplete outer toothed portion of described sun gear is provided with the jump ring groove, is provided with in the jump ring groove to make incomplete internal tooth portion and the spacing jump ring of incomplete outer toothed portion engagement.
After adopting above technological scheme, the beneficial effect that the present invention reaches is: the sun gear external diameter is processed into an elongated outer toothed portion, process incomplete outer toothed portion at outer toothed portion one end again, need not process two different tooth portions, tooth portion is roll flute simultaneously, improves machining accuracy, the simplified processing process flow process, the quality of product height strengthens transmission stability, reduces the transmission noise; The sun gear intermediate portion need not process tool withdrawal groove or jump ring groove, avoided sun gear processing tool withdrawal groove or jump ring groove stress to concentrate and caused the sun gear fracture, the sun gear rigidity improves, particularly when sun gear has fluctuating load, operating security is better, longer service life; The positioning step that the incomplete external tooth of sun gear forms cooperates the jump ring groove of the incomplete tooth of sun gear outer end to lock planet carrier jointly, when working environment changed, jump ring cooperated positioning step all the time with planet carrier locking, and locking effect is good, be difficult for loose or dislocation, safe in utilization.
The present invention adopts the incomplete internal tooth portion of the incomplete outer toothed portion engagement planet carrier of the elongated tooth of sun gear external diameter portion, by the jump ring of incomplete tooth portion outer end with the spacing transmission of planet carrier, overall structure is simple, compact, convenient processing and manufacture, cost of production is low, planet carrier is spacing firm, and the planet carrier transmission is stable, efficient is high, safe in utilization, the life-span is long.
