Abstract
The invention discloses a planet carrier floating structure of a reducer of a rolling mill. The structure comprises a planet carrier and is characterized in that the planet carrier is a single arm planet carrier which is provided with a planet shaft, wherein a planet wheel is fixedly installed on the planet shaft. The planet carrier is provided with a solar wheel assembly. The planet shaft is cylindrical, and the planet wheel is in transmission connection with an inner gear ring which is transmission connection with the solar wheel assembly. According to the structure provided by the invention, a transfer torque is positioned by flanks of the planet wheel, the solar wheel and the inner gear ring on the planet shaft so as to replace the previous transmission structure of the planet carrier fixedly supported by two bearings, so that a lot of processing time is saved, the efficiency is improved, the processing difficulty is greatly reduced, the production efficiency is improved, the cost is saved and the weight is reduced while the strength is ensured, and advantages for market competition are obtained.
Description
Technical field
The invention belongs to Gear Production manufacturing technology field, specifically, relate to a kind of roll-in mill speed reducer planet carrier floating structure.
Background technique
Planetary gears is made up of planet carrier, sun gear, internal gear and a plurality of planetary pinion, wherein be distributed with a plurality of planet wheel shafts on the planet carrier with one heart, each planetary pinion is installed on separately the planet wheel shaft, make each planetary pinion can with the sun gear outer gearing, again can with internal gear in mesh.Because planetary gears has advantages such as compact structure, stable drive, slewing range be wide, and is widely used on the multiple machinery.
Traditional roll-in mill speed reducer is owing to adopt large power overloading, planet carrier structure is general to adopt two sections bearings dead axles rotation output torques, but so often needs very large space to place bearing, and bearing designation is bigger, the price comparison height uses cost also than higher.
Summary of the invention
The technical problem to be solved in the present invention is to overcome above-mentioned defective, and a kind of reasonable in design is provided, the roll-in mill speed reducer planet carrier floating structure that takes up room little, that processing is simple and durable.
For addressing the above problem, the technical solution adopted in the present invention is:
A kind of roll-in mill speed reducer planet carrier floating structure comprises planet carrier, and it is characterized in that: described planet carrier is the single arm type planet carrier, and planet carrier is provided with planet axis, is installed with planet wheel on the planet axis; The sun gear assembly is arranged on the described planet carrier.
Described planet axis is cylindric, and planet wheel 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 the described sun gear jacking block is installed, the ball top is installed on the 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 the ball top is 0.5-1cm, and jacking block and the engagement of ball top.
Distance between described jacking block and the ball top is 0.8cm.
Owing to adopted technique scheme, compared with prior art, utilization of the present invention is contained in planet wheel on the planet axis and sun gear, moment of torsion is transmitted in ring gear flank location, replaces in the past that two bearing fixing support the planet carrier drive mechanisms, has saved a large amount of process times in proof strength, improved efficient, reduce difficulty of processing significantly, enhance productivity, save cost, alleviated weight, for market competition has obtained advantage.
The invention will be further described below in conjunction with the drawings and specific embodiments simultaneously.
Description of drawings
