The specific embodiment
Shown in Fig. 1～2, the utility model comprises support 36 and the reel 3 that is arranged on the support 36, in reel 3, be provided with planetary gear speed reducing mechanism, described support 36 is provided with the satellite gear erecting frame 2 that is used for fixing planetary gear speed reducing mechanism, described reel 3 one ends are installed on satellite gear erecting frame 2 peripheries by bearing 21, described satellite gear erecting frame 2 is a hollow structure, described satellite gear erecting frame 2 is sleeved on the periphery of sun wheel 12 in the described planetary gear speed reducing mechanism, be provided with hollow and the piston 28 that is sleeved on the sun wheel 12 is connected with piston 28 with an end at satellite gear erecting frame 2, the other end withstands on the brake facing group on the satellite gear erecting frame 2, the sliding structure of joining and being provided with formation hydraulic working oil chamber between described piston 28 and the satellite gear erecting frame 2, described hydraulic working oil chamber and the hydraulic circuit UNICOM that is arranged in satellite gear erecting frame 2 support bodys, described brake facing group comprises the interior brake facing 14 that outer brake facing 15 contacts with face with it, brake facing 14 and sun wheel 12 engagements in described, the cock body of described piston 28 is provided with at least two blind holes, and spring 32 is set in the described blind hole.Described planetary gear speed reducing mechanism comprises by bearing 21 and is sleeved on gear ring 20 on the satellite gear erecting frame 2, described gear ring 20 and satellite gear 13 engagements that are installed on the satellite gear erecting frame 2, described satellite gear 13 and sun wheel 12 engagements, described gear ring 20 is captiveed joint with reel 3.
Described planetary gear speed reducing mechanism is that reduction ratio is 1: 6 an one-level planetary reduction gear.Described planetary gear speed reducing mechanism comprises by bearing 21 and is sleeved on gear ring 20 on the satellite gear erecting frame 2, described gear ring 20 and satellite gear 13 engagements that are installed on the satellite gear erecting frame 2, described satellite gear 13 and sun wheel 12 engagements, described gear ring 20 is captiveed joint with reel 3.Described satellite gear 13 and sun wheel 12 all adopt the angular deflection gear, dwindle the space that drop-gear box and braking mechanism occupy greatly, make winch light small and exquisite, are more suitable for small crane and in-use performance cheaply.Described satellite gear erecting frame 2 support bodys are provided with hydraulic ram.Described braking mechanism comprises the hydraulic ram and the spring 32 of the built-in brake facing of built-in brake facing and driving.
When gear pair is installed, should guarantee that contact (area) pattern is no less than 45% along tooth depth, be no less than 60% along tooth length.The common normal size of the satellite gear of adorning is pressed 0.01mm by mark matching conformability franchise on the same pinion carrier.Except that O type circle 33, after being coated with anaerobic adhesive, all the other bolts and screw place be screwed into.All bolts and screw are by 8.8 grades of control screw-down torques.The test run front reduction gear is bought oil and is pressed test, and any leakage phenomenon does not have.The positive and negative car of retarder respectively tries 30min, and noise, leakage of oil, the too high phenomenon of temperature rise must not be arranged.Put quiet fluid after the test run, inner chamber cleans up, and greasy dirt, iron filings and other impurity must not be arranged.The oil seal lip place is coated with moderate lubrication fat when assembling.
Motion principle: during the winch rotation work, satellite gear 13 drives gear ring 20 work, drives sun wheel 12 by motor 23 and rotates, and sun wheel 12 drives satellite gear 13 work rotates reel 3.
High pressure oil is entered by oil inlet, promotes piston 28 and makes spring 32 compressions, and at this moment the internal friction sheet 14, and outside friction disc 15 separates, and brake is opened.When high pressure oil ends, spring 32 promotes piston 28 compression internal friction sheet 14 and outside friction discs 15, produce huge friction force between the interior outside friction disc and make sun wheel 12 brakings (this moment, motor 23 also quit work), sun wheel 12 passes to satellite gear 13 to braking moment, satellite gear 13 is given gear ring 20 brake-force transmission again, thereby make whole winch braking, produce good braking effect.
