Abstract
The utility model discloses a planet carrier floating structure of a roll mill speed reducer. The planet carrier floating structure comprises a planet carrier and is characterized in that the planet carrier is a one-arm planet carrier, a planet shaft is arranged on the planet carrier, a planet wheel is fixedly arranged on the planet shaft, and a sun wheel assembly is arranged on the planet carrier. The planet shaft is cylindrical, the planet wheel is in transmission connection with an inner gear ring, and the inner gear ring is in the transmission connection with the sun wheel assembly. According to the planet carrier floating structure, a torque is located and transmitted by using the planet wheel arranged on the planet shaft, the sun wheel and a gear side of the inner gear ring, two traditional bearings are replaced for fixedly supporting a planet carrier transmission structure, an amount of processing time is saved when the strength is ensured, the efficiency is improved, the processing difficulty is greatly reduced, the production efficiency is improved, the cost is saved, the weight is reduced, and the advantage is obtained for market competition.
Description
Technical field
The utility model belongs to Gear Production manufacturing technology field, specifically, relates to a kind of roll mill speed reducer planet carrier floating structure.
Background technique
Planetary gears is comprised of planet carrier, sun gear, internal gear and a plurality of planetary pinion, wherein on planet carrier, be distributed with one heart a plurality of planet wheel shafts, each planetary pinion is arranged on planet wheel shaft separately, make each planetary pinion can with the sun gear outer gearing, again can with internal gear in mesh.Because planetary gears has the advantages such as compact structure, stable drive, slewing range be wide, and be widely used on multiple machinery.
Traditional roll mill speed reducer is owing to adopting large power overloading, planet carrier structure is general adopts two sections bearings System of Rotating about Fixed Axis output torques, but so often needs very large space to place bearing, and bearing designation is larger, price comparison is high, uses cost also higher.
Summary of the invention
The technical problems to be solved in the utility model is to overcome above-mentioned defect, and a kind of reasonable in design is provided, take up room little, process simple and durable roll mill speed reducer planet carrier floating structure.
For addressing the above problem, the technological scheme that the utility model adopts is:
A kind of roll mill speed reducer planet carrier floating structure, comprise planet carrier, and it is characterized in that: described planet carrier is the single arm type planet carrier, is provided with planet axis on planet carrier, is installed with planet wheel on planet axis; The sun gear assembly is arranged on described planet carrier.
Described planet axis is cylindric, and planet gear transmission is connected with ring gear, the ring gear sun gear assembly that is in transmission connection.
Described sun gear assembly comprises the sun gear with ring gear engagement, and with subordinate's sun gear of planet wheel engagement.
Described planet carrier is to forge that quenching with Subsequent tempering is made and tensile strength reaches the planet carrier of 900MPa by the 42CrMo material.
In described sun gear, jacking block is installed, the ball top is installed on planet carrier, jacking block and ball top are in transmission connection.
The number on described ball top is two, and two ball tops are in transmission connection with jacking block respectively.
Distance between described jacking block and ball top is 0.5-1cm, and jacking block and the engagement of ball top.
Distance between described jacking block and ball top is 0.8cm.
Owing to having adopted technique scheme, compared with prior art, the utility model utilization is contained in planet wheel on planet axis and sun gear, ring gear flank location transmitting torque, replaces two bearing fixed support planet carrier drive mechanisms in the past, has saved a large amount of process times in proof strength, improved efficiency, the decrease difficulty of processing, enhance productivity, cost-saving, alleviated weight, for market competition has obtained advantage.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail simultaneously.
The accompanying drawing explanation
The structural representation that Fig. 1 is a kind of embodiment of the utility model.
