Abstract
The utility model relates to a rotating device for a small-tonnage lorry-mounted crane, which belongs to the rotating device of engineering machinery. A pedestal of the rotating device is connected with a lower vehicle, a connecting shaft is connected with a worm wheel, a flat key is arranged between the connecting shaft and the worm wheel, the connecting shaft is positioned on the worm wheel through a pressure cover and a bolt, an upper-end bearing and a lower-end bearing are respectively arranged at the upper end and the lower end of the worm wheel, and the upper-end bearing and the lower-end bearing are respectively compressed through an upper-end cover and a lower-end cover; and a hydraulic motor is connected onto the pedestal through a motor connecting disk, an output end of a worm is connected with the hydraulic motor, the front end and the rear end of the worm are connected with the pedestal through a front-end bearing and a rear-end bearing, an inner ring of the front-end bearing is compressed through a round nut and a lock washer, and an outer ring of the front-end bearing is compressed through the motor connecting disk. The rotating device has the advantages that: 1. the structure is simple, device parts are fewer, the manufacturing and use cost is lower, and the difficulty of after-sale services is reduced; and 2. the structure of a traditional-type rotating device is broken by the device, and the device is a new structure of the rotating device for medium and small-tonnage cranes.
Description
Technical field
The utility model relates to a kind of turning gear of construction machinery and equipment, is little tonnage lorry-mounted crane turning gear specifically.
Background technology
At present, the gyroscopic movement of medium and small tonnage lorry-mounted crane is realized that by turning gear traditional turning gear has two kinds: 1. reductor and pivoting support structure; 2. rack cylinder and sprocket structure.Their characteristics have: 1. structure is complicated, and used parts are more, and the situation that turning gear goes wrong is more, and the past-sale service difficulty is big.2. manufacturing cost and use cost is higher.
Summary of the invention
The purpose of this utility model is to provide a kind of: medium and small tonnage lorry-mounted crane turning gear 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 comprises: upper end cover, the upper end bearing, adapter shaft, worm gear, HM Hydraulic Motor, the motor terminal pad, circular nut and stop washer, preceding side bearing, bottom end cover, worm screw, bottom end bearing, base, rear end bearing, gland and screw, base links to each other with getting off, adapter shaft links to each other with getting on the bus, adapter shaft is connected with worm gear, between adapter shaft and worm gear, flat key is arranged, adapter shaft is positioned on the worm gear by gland and screw, the worm gear upper and lower side respectively is furnished with upper end bearing and bottom end bearing, and upper end bearing and bottom end bearing compress by upper end cover and bottom end cover respectively; HM Hydraulic Motor is connected on the base by the motor terminal pad, the worm screw mouth is connected with HM Hydraulic Motor, the worm screw front and back end is connected with base with rear end bearing by preceding side bearing, and the front end bearing inner ring compresses by circular nut and stop washer, and the outer ring compresses by the motor terminal pad.
Beneficial effect: owing to adopted technique scheme, the pressure oil that this turning gear is come from the lorry-mounted crane oil pump drives worm screw through HM Hydraulic Motor, and worm screw drives worm gear, worm gear drives output shaft, and then the gyroscopic movement of realization car load.Owing to adopted technique scheme, make turning gear simple in structure, the device parts are less, and manufacturing cost and use cost is lower, and the past-sale service difficulty is little, has reached the purpose of this utility model.
Advantage: 1, simple in structure, the device parts are less, and manufacturing cost and use cost is lower, and the past-sale service difficulty reduces.2, this device has been broken the structure of traditional turning gear, is a new structure of medium and small tonnage crane rotation device.
