The utility model has the advantages that: 1. the transmission efficiency is high, the structure is compact and the output torque is large; 2. the assembling is easy and the work efficiency of workers is improved; and 3. the number of the parts of the mechanism is small and the difficulty in after-sales service is reduced.
Description
Technical field
The utility model relates to a kind of integral type device for revolving and driving, particularly a kind of medium and small tonnage lorry-mounted crane integral type swing type mechanism.
Background technology
At present, the gyroscopic movement of medium and small tonnage lorry-mounted crane is realized that by swing type mechanism traditional swing type mechanism mainly comprises pivoting support and rotary reducer two large divisions.Its characteristics have: 1. driving efficiency is low.What rotary reducer adopted is the worm and gear transmission, and its worm screw is a straight sided axial worm, driving efficiency extremely low (about 0.5), and what pivoting support adopted is straight gear, the transmission net effciency is lower.2. assembly precision requires high.The back lash of necessary field adjustable reductor mouth miniature gears and pivoting support tooth during assembling, debugging is complicated.3. past-sale service difficulty is big.Because drive path is longer, complex structure, used parts are more, and the situation that reductor may go wrong is more, the maintenance trouble.
The utility model content
The purpose of this utility model is to provide a kind of: driving efficiency height, the medium and small tonnage lorry-mounted crane integral type swing type mechanism that assembly precision is low, the past-sale service difficulty is little.
The purpose of this utility model is achieved in that this swing type mechanism comprises: housing, bevel gear type pivoting support outer ring, steel ball, bevel gear type pivoting support inner ring, motor, rear side housing, bearing, straight pin, screw, screw, the motor terminal pad, lubricating cup and planar envelope worm screw, bevel gear type pivoting support inner ring links to each other with getting off, the outer ring links to each other with getting on the bus, some steel balls are arranged between the Internal and external cycle, bevel gear type pivoting support inner ring is connected on the housing by screw and straight pin, be bearing in the housing by bearing before and after the worm screw, Bearing support motor terminal pad and rear side housing compress, motor is installed on the motor terminal pad by the motor screw, the engagement of planar envelope worm and wheel is furnished with lubricating cup on the housing.
Beneficial effect: owing to adopted technique scheme, the pressure oil that this swing type mechanism is come by maneuvering valve from the lorry-mounted crane oil pump, drive the planar envelope worm screw through HM Hydraulic Motor, worm screw drives the bevel gear type pivoting support, wherein the pivoting support outer ring is the helical wheel structure, thereby realizes the gyroscopic movement of car load.Adopted the planar envelope worm drive, i.e. worm and helical gear transmission, the transmission of this type of transmission contact is more, the driving efficiency height; Need not to adjust gear backlash during the car load assembling, alleviated the complexity of debugging, assembly precision is low; Drive path is simple, and mechanism's parts are less, and the past-sale service difficulty is little, has reached the purpose of this utility model.
Advantage:
1, this swing type mechanism is owing to adopted the planar envelope worm drive, and the transmission of contact is more, and driving efficiency is higher, compact conformation, and output torque is big; Break down no pressure when providing at car load, can manually rotate, field work is brought convenience.
2, the assembly precision requirement is low, is easy to assembling, need not to adjust gear backlash during the car load assembling, has alleviated the complexity of debugging, has improved workman's efficiency.The back lash is little in addition, rocks in the time of can avoiding car load to stop.
3, drive path is simple, and mechanism's parts are less, and the past-sale service difficulty reduces.
4, this mechanism has broken that traditional pivoting support needs and rotary reducer is combined, and the status that could realize the car load gyroscopic movement is a developing direction of medium and small tonnage crane rotation mechanism.
