Description

The crawler crane retarder

Technical field

The utility model belongs to the crane facility technical field, is specifically related to a kind of crawler crane retarder.

Background technique

Crawler crane is a kind of crane gear that is widely used in all fields of national economy, have that grounding pressure is little, radius of turn is little, the lift heavy operation need not make a jack, can be with and carry the advantage such as travel, lifting performance is good, and can be by additional device, carry out a worker, earth and rock works, in industries such as power construction, urban construction, bridge construction, petrochemical industry, water conservancy and hydropowers, have the irreplaceable status of other crane gear such as truck crane, wheel mounted crane, all terrain crane.All increasing along with quality, the volume of the article that need handling and the lifting altitude that will reach, crawler crane more and more shows its superiority.

The main matching parts of crawler crane is selected external product, and motor is selected the automatically controlled imported with original packaging product of american commings; Hydraulic element adopt German BOSCH-REXROTH product; The speed reducer of major and minor lifting device, luffing device and traveling gear generally adopts German BOSCH-REXROTH planetary speed reducer.Because expensive, the maintenance of import retarder and the shortcoming such as after sales service is untimely, maintenance cost is high, along with the manufacturing continuous progress of domestic retarder, present domestic retarder has faced the situation that replaces the import retarder.

Summary of the invention

Be the problems such as it is expensive, after sales service is untimely, maintenance cost is high that solve the import retarder, the utility model has designed a kind of crawler crane retarder, domestic replacement import, and common retarder replaces planetary reducer, both reduced the retarder cost, guaranteed again to install and use reliable.

For achieving the above object, the technical solution adopted in the utility model is:

This retarder comprises casing, an output gear, an output shaft, driving gear, the input gear axle, transition gear, gear shaft, No. two output gears, No. two output shafts, gear and flange, the input gear axle is installed in the housing bearing seat by the bearing of its two ends configuration, on the input gear axle driving gear is installed, gear shaft is installed in the housing bearing seat by the bearing of its two ends configuration, transition gear is installed on the gear shaft, No. two output shaft is installed in the housing bearing seat by the bearing that its two ends configure, No. two output gears of installation and gear on No. two output shafts, No. one output shaft is installed in the housing bearing seat by the bearing that its two ends configure, the flange that is installed on the casing is positioned on the axle head of an output shaft, an output gear is installed on the output shaft, an output gear engagement driving gear, input gear axle engagement transition gear, No. two output gears of gear shaft engagement, whole formation retarder.

During installation, the input gear axle utilizes the involute splines of its axle head to link by hydraulic couplers and motor, the gear couplings reel of gear through being meshed with it, and No. one output shaft connects oil hydraulic pump; During work, the input gear axle transfers torque on No. two output shafts by the two-stage gear transmission, transfers torque to reel with hoisting heavy by gear; The input gear axle transfers torque on output shaft by the one-level gear transmission, drives oil hydraulic pump, allows the oil hydraulic pump be other device fuel feeding.

The utlity model has following advantage: 1, the input gear axle utilizes the involute splines of its axle head to link by hydraulic couplers and motor, hydraulic couplers install and use the safety of greatly having protected retarder; 2, this retarder has hoisting and is equivalent to the function of motor, this mechanism had both reached the effect of hoisting heavy, saved again and used the driven by motor oil hydraulic pump, saved the space, saved simultaneously motor cost, and two functions of this retarder are non-to be carried out simultaneously, has greatly alleviated the working pressure of retarder; 3, simple in structure, rationally compact, lightweight, bearing capacity is large, and stable working is reliable, and bearing capacity and the wear resistance of gear are high, long service life, and rotary inertia is little, improves the braking ability of hoist.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Among the figure: 1 casing; No. 2 output gears; No. 3 output shafts; 4 driving gears; 5 input gear axles; 6 transition gears; 7 gear shafts; 8, No. two output gears; 9 No. two output shafts; 10 gears; 11 flanges.

Embodiment

As shown in Figure 1, this retarder comprises casing 1, an output gear 2, an output shaft 3, driving gear 4, input gear axle 5, transition gear 6, gear shaft 7, No. two output gears 8, No. two output shafts 9, gear 10 and flange 11, input gear axle 5 is installed in casing 1 bearing support by the bearing of its two ends configuration, driving gear 4 is installed on the input gear axle 5, gear shaft 7 is installed in casing 1 bearing support by the bearing of its two ends configuration, transition gear 6 is installed on the gear shaft 7, No. two output shaft 9 is installed in casing 1 bearing support by the bearing that its two ends configure, No. two output gears 8 of installation and gear 10 on No. two output shafts 9, No. one output shaft 3 is installed in casing 1 bearing support by the bearing that its two ends configure, the flange 11 that is installed on the casing 1 is positioned on the axle head of an output shaft 3, an output gear 2 is installed on the output shaft 3, output gear 2 engagement driving gears 4, input gear axle 5 engagement transition gears 6, No. two output gears 8 of gear shaft 7 engagements, whole formation retarder.
