Abstract
Provided is an output structure of a lorry-mounted crane turning device. The utility model belongs to the output structure of an engineering machinery turning device. A planet wheel and a planet shaft of the turning device are installed on circumferential holes of a planet carrier. Bolts are arranged on the planet carrier in a peripheral direction. The planet carrier is supported by an upper end conical roller bearing and a lower end conical roller bearing. A planet wheel backup rings and a cylindrical roller are sleeved on a planet wheel shaft. The planet wheel backup rings are placed on two ends of the planet wheel. The cylindrical roller is arranged between the planet wheel and the planet wheel shaft. The planet wheel is connected with a sun wheel in a gearing mode. An output shaft of the planet carrier is a turning pinion. The output structure is simple in structure, convenient to manufacture, low in cost, and convenient to install and maintain. Besides, products are high in reliability, and the integral type planet carrier, a planet wheel structure supported by the cylindrical roller, and a planet carrier structure fixed and supported by two ends conical rollers all guarantee the reliability of the products.
Description
Technical field
The utility model relates to a kind of export structure of construction machinery and equipment turning gear, particularly a kind of export structure of lorry-mounted crane turning gear.
Background technology
At present, the gyroscopic movement of lorry-mounted crane is realized by turning gear, turning gear is as a vitals on the lorry-mounted crane, because its work frequency of utilization is higher, particularly in that to start or stop the impact load that moment bears larger, thus improper if the export structure of turning gear designs, and the phenomenon that bearing failure, pinion carrier fracture, revolution miniature gears come off often appears in operation, cause complete machine to work, also can cause pivoting support to damage when serious.The export structure of tradition turning gear is: 1. pinion carrier and revolution miniature gears separate structure, both adopt flat key or spline joint.This structure is prone to pinion carrier and is connected the loosening revolution miniature gears obscission that causes with the revolution miniature gears, and the gap between the key is inevitably during spline joint simultaneously, turn round positive and negative motion moment existence and turns round in opposite directions, turns round miniature gears and also easily comes off; 2. satellite gear adopts ball-bearing casing or cylindrical roller bearing supporting.The satellite gear diameter of axle and satellite gear wall thickness are difficult for guaranteeing, cause satellite gear or planet axis to damage; 3. two ends ball-bearing casing supporting or floating structure are mostly adopted in the pinion carrier supporting.The ball-bearing casing load-carrying capacity of this structure is not strong and pinion carrier is stressed bad, easily causes bearing failure and pinion carrier to damage.
Summary of the invention
The purpose of this utility model is to provide a kind of: the novel export structure that uses the lorry-mounted crane turning gear reliable, simple in structure, compact, that manufacturing cost and use cost is lower.
The purpose of this utility model is achieved in that this turning gear export structure comprises: pinion carrier, revolution miniature gears, satellite gear, planet wheel spindle, cylindrical roller, satellite gear packing ring, screw, upper end tapered roller bearing, lower end tapered roller bearing; Satellite gear and planet wheel spindle are installed on the circumferential apertures of pinion carrier, the pinion carrier circumferential directions has screw, pinion carrier is by upper end tapered roller bearing and the supporting of lower end tapered roller bearing, be socketed with satellite gear packing ring and cylindrical roller at planet wheel spindle, the satellite gear packing ring is positioned at the satellite gear two ends, cylindrical roller is between satellite gear and planet wheel spindle, and satellite gear is that gear is connected with sun wheel, and the output shaft of pinion carrier is the revolution miniature gears.
Beneficial effect is owing to adopted technique scheme, the pressure oil that this turning gear is come from the lorry-mounted crane oil pump, drive the sun wheel rotation through HM Hydraulic Motor and balance cock, sun wheel drives satellite gear, and satellite gear drives output shaft, and then realizes the gyroscopic movement of car load.Relative motion between screw restriction planet wheel spindle and the pinion carrier, the axial motion of satellite gear gaskets limit satellite gear.Pinion carrier adopts two each unidirectional fixed form of fulcrum, and upper and lower side adopts the tapered roller bearing supporting, and the stressing conditions of axle is better, and load-carrying capacity is stronger, reduces the damageable degree of axle.Planetary gear structure adopts cylindrical roller, and compact conformation can make the planet wheel spindle diameter do greatly, and the satellite gear wall thickness increases simultaneously, better guard rows star-wheel and planet wheel spindle.Pinion carrier is made a part with the revolution miniature gears, is convenient to processing and manufacturing, better guarantees the right alignment of upper and lower side bearing installation place, and that can avoid adopting key to connect causing is loosening.So that this turning gear export structure has following characteristics: 1. upper and lower side adopts the tapered roller bearing supporting, and load-carrying capacity is stronger, better protects the structure of axle, and pinion carrier adopts the two supports structure, and stressing conditions is better; 2. planetary gear structure adopts cylindrical roller, and compact conformation can make the planet wheel spindle diameter do greatly, and the satellite gear wall thickness increases simultaneously, better guard rows star-wheel and planet wheel spindle; 3. pinion carrier is made of one with the revolution miniature gears, is convenient to processing and manufacturing, better guarantees the right alignment of upper and lower side bearing installation place, and that avoids adopting key to connect causing is loosening.Above characteristics are so that this turning gear has reached the purpose of utility model.
Advantage:
1, simple in structure, easily manufactured, and cost is lower.Because pinion carrier and revolution miniature gears are made of one, but the pinion carrier two ends bearing place clamped one time be installed finished, right alignment easily guarantees.Integral planet carrier can adopt cast structure in addition, compares conventional confguration, and manufacturing cost is also lower.Because simple in structure, installation and maintenance are also very convenient.
2, product reliability is higher.The planetary gear structure of integral planet carrier, cylindrical roller supporting, the reliability that two terminal circle taper roller bearing fixed bearing formula planet carrier structure has all guaranteed product.Can overcome on the one hand the revolution miniature gears phenomenon that gets loose, simultaneously less because of load-carrying capacity with impact that the satellite gear supporting structure that causes more greatly damages, the pinion carrier phenomenon of rupture.
