Description
Technical field
The utility model relates to a kind of hydraulic pressure lift winding plants, are used for large excavator field.
Background technique
It is all common parallel axle speed reducing machine, huge structure transmission that existing large excavator, which promotes winding plant, currently on the market
Precision is low, service life is short, maintenance capacity is big, high production cost, use and maintenance cost are big.
Summary of the invention
The utility model provides a kind of hydraulic pressure lift winding plant, is used for large excavator field, its object is to solve
Certainly large excavator existing in the prior art promotes that winding plant huge structure, transmission accuracy is low, service life is short, maintenance capacity
Greatly, high production cost, the problems such as use and maintenance cost is big.
The utility model uses following technical scheme:
A kind of hydraulic pressure lift winding plant, including support (6), reel (1), it is characterised in that: left and right on the support (6)
Two sides are symmetrical arranged driving device, planet-gear speed reducer (2), axle bed (3), and the driving device includes hydraulic motor (5), institute
The output shaft for stating hydraulic motor (5) passes through the through-hole being arranged on axle bed (3) and drives planet-gear speed reducer (2) input terminal,
The planet-gear speed reducer (2) is symmetrically placed in, and reel (1) is internal, and the output end of the planet-gear speed reducer (2) drives
The reel (1) rotates synchronously, and planet-gear speed reducer (2) outer end is supported and fixed on the axle bed (3).
Transmission gear (9) outer ring of the planet-gear speed reducer (2) is equipped with flange (4), and reel (1) side wall is
The gusset (7) of axially disposed centre bore, the planet-gear speed reducer (2) are inserted into the centre bore, the flange (4) and institute
Gusset (7) is stated to be spirally connected；The end flange disk of planet-gear speed reducer (2) external shell is fixedly connected with the axle bed (3)；
The output shaft of the hydraulic motor (5) passes through the drive of the through-hole and the planet-gear speed reducer (2) that are arranged on the axle bed (3)
The connection of moving gear (8) spline.
Reel (1) horizontal cross is set between the axle bed (3).
The advantages of the utility model, is as follows:
Hydraulic pressure lift winding plant is compact-sized, small in size, light-weight, noise is small, production cost is low, an overhaul time 4
The hoisting mechanism of freedom from repairs reduces production cost and use and maintenance cost, reducing makes almost without electric elements in year
With and maintenance cost, the mode of hydraulic motor direct connection speed reducer keep the speed reducer at both ends more synchronous, reel operation it is more stable.
