Summary of the invention
The utility model provides a kind of built-in promotion winding plant, is used for large excavator field, its object is to
It solves large excavator existing in the prior art and promotes that winding plant huge structure, transmission accuracy is low, service life is short, maintenance
The problems such as amount is big, high production cost, big use and maintenance cost.
The utility model uses following technical scheme:
A kind of built-in promotion winding plant, including support (6), reel (1), it is characterised in that: left on the support (6)
Right two sides are symmetrical arranged driving device, planet-gear speed reducer (2), axle bed (7), and the driving device includes motor (5), shaft coupling
Device (4) and splined shaft (3), the motor (5) drive the planetary gear reduction by the shaft coupling (4), the splined shaft (3)
Fast machine (2) input terminal, the splined shaft (3) pass through the through-hole being arranged on axle bed (7), and the planet-gear speed reducer (2) is symmetrical
The reel (1) that is placed in is internal, and planet-gear speed reducer (2) output end drives the reel (1) to rotate synchronously, the planet
Gear reduction unit (2) outer end is supported and fixed on the axle bed (7).
Transmission gear (13) outer ring of the planet-gear speed reducer (2) is equipped with flange (9), reel (1) side wall
For the gusset (8) of axially disposed centre bore, the planet-gear speed reducer (2) is inserted into the centre bore, the flange (9) with
The gusset (8) is spirally connected;The end flange disk of planet-gear speed reducer (2) external shell and the axle bed (7) fixed company
It connects;The splined shaft (3) passes through in the through-hole being arranged on axle bed (7) and the planet-gear speed reducer (2) driving gear (12)
Spline connection.
The shaft shoulder (11) are arranged in splined shaft (3) splined end, the shaft shoulder (11) side and the planetary gear speed-reduction
Machine (2) end face is engaged.
The reel (1) is horizontally placed between the axle bed (7).
The advantages of the utility model, is as follows:
Built-in promotion winding plant is compact-sized, small in size, light-weight, noise is small, production cost is low, an overhaul time
(4 years) interior freedom from repairs, reduces production cost, reduces use and maintenance cost.

Specific embodiment:
Specific embodiments of the utility model will be further explained with reference to the accompanying drawing.
Fig. 1,4 show a kind of built-in promotion winding plant, including support 6, reel 1, the left and right sides on the support 6
It is symmetrical arranged driving device, planet-gear speed reducer 2, axle bed 7, the driving device includes motor 5, shaft coupling 4 and splined shaft
3, the motor 5 drives 2 input terminal of planet-gear speed reducer, the spline by the shaft coupling 4, the splined shaft 3
Axis 3 passes through the through-hole being arranged on axle bed 7, and the planet-gear speed reducer 2 is symmetrically placed in inside reel 1, the planetary gear
2 output end of speed reducer drives the reel 1 to rotate synchronously, and 2 outer end of planet-gear speed reducer is supported and fixed on the axle bed 7
On.
The planet-gear speed reducer 2 is outsourcing piece, model WLT450, max. output torque 450000Nm, production
Producer is Beijing Hua Dewanli hydraulic machinery Co., Ltd.
13 outer ring of transmission gear that Fig. 1 shows the planet-gear speed reducer 2 is equipped with flange 9,1 side wall of reel
For the gusset 8 of axially disposed centre bore, the planet-gear speed reducer 2 is inserted into the centre bore, the flange 9 and the muscle
Plate 8 is spirally connected;The end flange disk of 2 external shell of planet-gear speed reducer is fixedly connected with the axle bed 7;The splined shaft
3 pass through the through-hole being arranged on axle bed 7 connect with the planet-gear speed reducer 2 driving 12 internal spline of gear.
Fig. 1 shows 3 splined end of the splined shaft setting shaft shoulder 11,11 side of the shaft shoulder and the planetary gear reduction
Fast 2 end face of machine is engaged.
The reel 1 is horizontally placed between the axle bed 7.
Working principle:
The symmetrically arranged motor in two sides drives the splined shaft to rotate by shaft coupling, described in the splined shaft drive
Planet-gear speed reducer rotation, the planet-gear speed reducer drive the spool turns.
