Abstract
The utility model discloses a multi-function speed changing roller device. The utility model is characterized in that a planetary gear frame is arranged in the roller with a concave surface, two half shafts of the planetary gear frame extend out of the roller through a shaft core bearing of the roller with a concave surface and are positioned through a positioning bearing of the roller, wherein, one half shaft of the planetary gear carrier has a hollow structure and an input shaft is arranged in the half shaft, both ends of the input shaft are respectively connected with a motor and a cycloidal gear on the planetary gear, and meanwhile, both ends are also connected with center wheels in the roller with a concave surface; the shaft end of the other half shaft of the planetary gear carrier is provided with a clutch. The utility model has the advantages of compact structure, small starting torque, low running fault rate, etc.
Description
The utility model relates to a kind of multi-function variable-speed roller device, is applicable to material conveying device.
On commercial production, travelling apron is that a kind of adaptive capacity is strong, and field of application is conveying machinery the most widely.Travelling apron can carry moist or drying, powdery or block various materials, and it is big that it has traffic capacity, the characteristics that fed distance is long; It also has simple in structure, and it is reliable to operate steadily, the advantage that transmission efficiency is high.So travelling apron is present most widely used conveying machinery.Cylinder is an indispensable core component in the travelling apron, and the structure of cylinder and quality directly have influence on the integral level of travelling apron.Present stage, there was multiple cylinder in China, produced such as Jilin Province's east wind machine works, and the patent No. is 90206675 cycloid speed-reducing drums.These cylinders all have result of use preferably.But present cylinder in use all exposes following weak point in various degree: the one, and transferring adhesive tape is sideslip on cylinder easily; The 2nd, no overload protection function; The 3rd, no soft start and variable-speed operation function.Above-mentioned preceding two kinds of situations can cause damage to cylinder and other equipment, and the third can reduce the service life and the economy of total system.
The purpose of this utility model provides a kind of can the adhesive tape automatic deviation correction can not being damaged by preventive device when overload, have the multi-function variable-speed roller device of soft start and variable-speed operation function, to remedy the deficiency of prior art.
The purpose of this utility model is achieved in that a kind of multi-function variable-speed roller device, comprise the concave surface cylinder, it is characterized in that: in the concave surface cylinder planetary gear carrier is set, two semiaxis of planetary gear carrier hold by concave surface drum shaft mandrel and stretch out the concave surface cylinder and pass through cylinder location bearing location; Wherein planetary gear carrier semiaxis is a hollow structure, wherein be provided with input shaft, one end of input shaft is in relation to electrical motor by coupler, and the Cycloidal Wheel on the planetary gear carrier is in relation to the other end of input shaft, also is in relation to the center gear in the concave surface cylinder simultaneously; The axle head of another semiaxis of planetary gear carrier is provided with power-transfer clutch.
Described multi-function variable-speed roller device is characterized in that the axle head of another semiaxis of planetary gear carrier is provided with magnetic clutch; Concrete structure is that the axle head of another semiaxis of planetary gear carrier is a castellated shaft, is with the clutch awl on the castellated shaft, has retracing spring and clutch tapered joint to touch in the magnetic clutch, on the clutch awl conical surface cone-disk clutch sheet is arranged.
Characteristics such as the utlity model has compact conformation, staring torque is little, and transferring adhesive tape is felt relieved, and the operating troubles rate is low.
Below by embodiment the utility model is further described.
Fig. 1 is a kind of example structure scheme drawing of the utility model;
Fig. 2 is the axle head and the magnetic clutch structural representation of another semiaxis of embodiment planetary gear carrier.
1 is electrical motor among the figure, and 2 is input shaft, and 3 is Cycloidal Wheel, 4 is planetary gear carrier, and 5 is center gear, and 6 is the concave surface cylinder, 7 is magnetic clutch, and 8 is the cylinder location bearing, and 9 is coupler, 10 is the planetary gear carrier semiaxis, and 11 is transferring adhesive tape, and 12 is bearing seat, 13 are the clutch awl, 14 is the cone-disk clutch sheet, and 15 is retracing spring, and 16 is magnet coil.
The working process of present embodiment is that transferring adhesive tape 11 is loaded on the concave surface cylinder 6, electrical motor 1 and magnet coil 16 are simultaneously during startup, magnet coil 16 the magnetic field of electric generation makes clutch awl 13 on the castellated shaft of another semiaxis 10 of planetary gear carrier 4 obtain power to unclamp cone-disk clutch sheet 14, thereby make the semiaxis 10 of planetary gear carrier 4 and planetary gear carrier 4 be in free state, the rotation of electrical motor 1 makes concave surface cylinder 6 enter the operation of differential gear train state.Rotating speed increase along with electrical motor 1, input shaft 2, planetary gear carrier 4 and Cycloidal Wheel 3, center gear 5 drags concave surface cylinder 6 and does the speedup motion, after reaching certain rotating speed, control circuit cuts off the power supply of magnet coil 16, retracing spring 15 promotes clutch awl 13 and makes 14 combinations of cone-disk clutch sheet, thereby makes differential gear train change planet circular system over to, and promptly the semiaxis 10 of planetary gear carrier 4, planetary gear carrier 4 are fixed, make concave surface cylinder 6 reach rated speed of rotation, the soft start of finishing device.When magnet coil 16 was in long-term "on" position, device just was in the differential gear train state always, promptly exports second kind of rotating speed, realized variable-speed operation.When overload occurring in the operational process, the torque force of another semiaxis 10 of planetary gear carrier 4 surpasses the friction torque power that retracing spring 15 compression cone dish clutch-plates 14 are produced, thereby the semiaxis 10 of planetary gear carrier 4 is freely rotated, and plays overload protective function.
