The utility model belongs to the hydraudynamic drive technical field, specifically a kind of hydraulic synchronization transmission of realizing constant-power, stepless speed-regulating and stepless torque changing expeditiously.
Background technique:
The existing power transmission solution that is used for constant-power, stepless speed-regulating and stepless torque changing mainly contains various friction type stepless speed adjusting gears, metal band type stepless speed adjusting gear, and fluid torque converter.Friction type stepless speed adjusting gear power seldom can reach more than 100 kilowatts, and efficient is between 40%-90%; Metal band type stepless speed adjusting gear transmitting torque seldom can surpass 300Nm, and efficient is at 70%-92%; The fluid torque converter transmitted power is very big, but peak efficiency seldom surpasses 85%, and efficient scope is not wide, is a kind of kind of drive of poor efficiency; At high-power power transmission transmission field, can realize that in the world the constant-power, stepless speed-regulating average efficiency surpasses 85% and almost do not have at present, this also is people's technical barriers anxious to be solved,
I have invented a kind of " hydraulic self-synchronous device " in August, 2006, the patent No. is 2006100698771, it is provided with input shaft, output shaft, solid of rotation, bucket wheel, planet wheel, fusible plug, feature is that solid of rotation is made up of shell and left and right sides end cap, a rotating body is provided with support, bucket wheel is bearing on solid of rotation left end cap and the support by bucket wheel axle, the planet wheel cantilever support is on bucket wheel axle, engagement in planet wheel and the sun gear, input shaft is connected with solid of rotation, sun gear is connected with output shaft, its deficiency is that casing oil is through oil circuit, after throttling arrangement enters bearing support, enter a rotating body again, with the time of participation work and adjusting soft start, its deficiency is can not stepless speed regulation and stepless torque changing.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and the hydraulic synchronization transmission of a kind of power transmission constant-power, stepless speed-regulating and stepless torque changing and soft start is provided
The utility model can reach by following measure:
A kind of hydraulic synchronization transmission, be provided with input shaft, output shaft, solid of rotation, bucket wheel, planet wheel, fusible plug, it is characterized in that being provided with bull gear, bull gear is meshed with sun gear through planet wheel, planet wheel is connected with bucket wheel, planet carrier connects by the sticking break of liquid with casing, and input shaft connects with sun gear, and output shaft connects with bull gear.
Planet wheel can adopt double planetary gear structure in the utility model, the second seniority among brothers and sisters star-wheel is connected with bucket wheel, can guarantee like this under two kinds of output speeds, output speed direction unanimity, if adopt single then two kinds of output speed directions opposite, also can adopt the method that list is double and deposit, can have multiple output speed to select like this.
Power transmission mode of the present utility model is realized in the following way: power passes to sun gear by input shaft, pass to second level planetary pinion by sun gear again, pass to first order planetary pinion by secondary planetary gear again, primary planet pinion and bucket wheel combine as a whole, and planet carrier links to each other with casing by the sticking break of liquid, power is passed to bull gear again by primary planet pinion, finish whole power transmission process, when centrifugal moment in the bucket wheel can balance input and output moment difference the time, power can not have the transmission of slippage ground, when the sticking break braking of liquid planet carrier, how many entire mechanism can realize stepless change and stepless torque changing by liquid in gap between the friction plate of the sticking break of regulator solution and the adjusting bucket wheel as the plane table thermoconductivity meter transferring power.
The utility model can be realized 10-10000 kilowatt of powerdriven constant-power, stepless speed-regulating and stepless torque changing and soft start, and average efficiency is about 95%, at minimum speed and maximum speed efficient is about 99%, can be widely used on automobile, engineering machinery, mining machinery, power plant, steel mill, the chemical machinery, on stepless change and stepless torque changing and soft start, superior performance is arranged, on the heavy load starting that solves high power load, bigger advantage is arranged.
