Abstract
The invention discloses a transmission mechanism of an electric hoist. A gear box and a drum are coaxially mounted together, and an upper central spindle is mounted between the gear box and the drum through a bearing; the gear box and the drum are mounted and fixed on a bracket through the central spindle in the middle; the bracket is mounted on a fixing frame; a control big internal gear is mounted and fixed at the inner end of the gear box through the central spindle in the drum so that a fixed big internal gear and the control big internal gear have the same addendum circle and have a difference of two teeth; the fixed big internal gear and the control big internal gear are coaxially mounted and fixed at the outer end of the gear box; a planetary gear is mounted on a planetary gear frame; a rotation center of the planetary gear frame is coaxially fixed to the axis of a motor, and the meshing relationship between the planetary gear and the fixed big internal gear and between the planetary gear and the control big internal gear is ensured at the same time; and a control brake wheel is mounted and fixed on the central spindle on the outer side of the drum.
Description
Technical field
The present invention relates to the gearing of a kind of transmission device, particularly a kind of electric block, belong to electric block transmission and technical field of structures.
Background technology
Electric block is a kind of wherein machinery commonly used, uses widely in the place that lifting weight is little.At present, electric block is in transmission and configuration aspects, all be transmission and the frame mode that the direct and common speed reduction gearing of reel is connected, or adopt common planetary type of drive, no matter the sort of type of drive, all exist structure more complicated, fault rate higher, control inconvenience, the higher defective of cost.
Summary of the invention
The objective of the invention is to: a kind of transmission device of electric block is provided, overcome existing electric block higher in existing structure more complicated aspect structure and the transmission, fault rate, control inconvenience, the higher defective of cost.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: a kind of transmission device of electric block, it is by motor, gear case, planetary gear carrier, planetary wheel, fixedly big internal gear, drum brake, control big internal gear, bearing, mandrel, reel, fixed mount, support, control brake device, control brake wheel institute are formed.It is characterized in that: described gear case is cylindric, be installed together gear case and reel coaxial line, or both make all-in-one-piece siamesed form, pass through the bearing installation mandrel in the middle of described gear case and the reel, simultaneously, gear case and reel are fixed on above the support by the mandrel in the middle of it, support is installed in above the fixed mount in advance, described control big internal gear is fixed on the gear case inner end by the mandrel in the reel, described fixedly big internal gear is to have identical tooth top circle with the control big internal gear, both differ the gear of two teeth, fixedly be fixed on the outer end of gear case big internal gear and control big internal gear coaxial line, described planetary wheel is installed in above the planetary gear carrier, be fixed together the centre of gration of planetary gear carrier and electrical axis coaxial line, simultaneously, planetary wheel with, fixing big internal gear, the control big internal gear forms the ingear relation, described control brake wheel is fixed on above the mandrel in the reel outside, and described control brake device is the incorporate element that is used with the control brake wheel.
Principle of work of the present invention is: when the control brake device is to be used with the control brake wheel to be in braking mode, drum brake is in when loosening, mandrel is in stationary state with the control big internal gear, reel and gear case are in free state, the driven by motor planetary gear carrier rotates, because the control big internal gear maintains static, so, planetary wheel is just around controlling big internal gear while rotating autobiography, planetary wheel drives fixedly again, and big internal gear rotates, because fixedly big internal gear and reel are fixed together, so, begin to rotate under planetary drive, both reduction ratios are that fixedly big internal gear is in the gear number of teeth of stationary state with the number of teeth difference of controlling big internal gear divided by one of them.When drum brake is in braking mode, control brake device is to be used when being in relaxation state with the control brake wheel, then reel maintains static, the control big internal gear is in the dry run state, changes the hand of rotation of motor, then can change the hand of rotation of reel.
Beneficial effect: the present invention can overcome existing electric block higher in existing structure more complicated aspect structure and the transmission, fault rate, control inconvenience, the higher defective of cost.

Fig. 1 is a structure principle chart of the present invention;
Shown in the figure: 1, motor; 2, gear case; 3, planetary gear carrier; 4, planetary wheel; 5, fixing big internal gear; 6, drum brake; 7, control big internal gear; 8, bearing; 9, mandrel; 10, reel; 11, fixed mount; 12, support; 13, control brake device; 14, control brake wheel.
The specific embodiment
With gear case (2) and reel (10) coaxial line be installed together, or both make all-in-one-piece siamesed form, in the middle of gear case (2) and reel (10), install mandrel (9) by bearing (8), simultaneously, gear case (2) and reel (10) are fixed on above the support (12) by the mandrel (9) in the middle of it, support (12) is installed in above the fixed mount (11) in advance, to control big internal gear (7) and be fixed on gear case (2) inner end by the mandrel (9) in the reel (10), making fixedly in the design of parameter, big internal gear (5) is to have identical tooth top circle with control big internal gear (7), it is poor that both differ two teeth, fixedly be fixed on the outer end of gear case big internal gear (5) and control big internal gear (7) coaxial line, planetary wheel (4) is installed in above the planetary gear carrier (3), be fixed together the centre of gration of planetary gear carrier (3) and motor (1) axis coaxle line, guarantee planetary wheel (4) and fixing big internal gear (5) simultaneously, control big internal gear (7) forms the ingear relation, control brake wheel (14) is fixed on above the mandrel (9) in the reel outside, described control brake device (13) is the incorporate element that is used with control brake wheel (7).
Claims (2)
1. the transmission device of an electric block, it is by motor, gear case, planetary gear carrier, planetary wheel, fixedly big internal gear, drum brake, control big internal gear, bearing, mandrel, reel, fixed mount, support, control brake device, control brake wheel institute are formed.It is characterized in that: fixedly big internal gear (5) be have identical tooth top circle with control big internal gear (7), that both differ two teeth is poor.
2. according to the transmission device of claims 1 described a kind of electric block, it is characterized in that: star gear (4) is with fixedly big internal gear (5), control big internal gear (7) form the ingear relation simultaneously.
