Abstract
The invention provides a planetary gear transmission coupling with an overload protection function. The planetary gear transmission coupling with the overload protection function comprises a front shell, a planetary gear transmission mechanism, protecting pins and a rear shell. By means of deflection of a planetary gear, the coupling can compensate for the radial offset generated during mounting as much as possible, and can also compensate for the radial offset of two dynamically changing connecting shafts in the operation process. The uniform load characteristic of planetary transmission is good, larger torque can be borne, and large-torque stable transmission is achieved. In addition, when suffering an impact load or overload, the protecting pins fracture to achieve the overload protection function. After the overload problem is solved, the damaged protecting pins are taken out, new protecting pins are inserted, and then the coupling can operate normally. The coupling has good repairability.
Description
Technical field
The present invention relates to shaft coupling technical field, be specifically related to a kind of Planetary Gear Transmission shaft coupling with overload protection.
Background technology
In mechanical transmission fields, shaft coupling will be used in most cases, be responsible for the moment of torsion of driving shaft is passed to driven shaft.Conventional shaft coupling requires that the axiality of connecting shaft is the highest; poor to the radial deflection compensation ability of two connecting shafts; and major part shaft coupling does not the most possess the ability of overload protection when by shock loading or overload; Given this plant situation, now design a kind of Planetary Gear Transmission shaft coupling with overload protection.
Summary of the invention
The problem existed for appeal shaft coupling, the present invention designs a kind of Planetary Gear Transmission shaft coupling with overload protection.Compensate radial deflection when installing as far as possible; the radial deflection of two connecting shafts dynamically changed is can also compensate in operation process; utilize Gear Planet Transmission to realize high pulling torque stably to transmit, and protection pin fracture is played overload protection and acted on when by shock loading or overload.
The scheme that the present invention uses is as follows:
A kind of Planetary Gear Transmission shaft coupling with overload protection; including procapsid, planetary gear mechanism, protection pin and back casing; described planetary gear mechanism includes that power inputs centre wheel, and fixed annulus, front end planetary gear, planet carrier, movable internal gear, end planetary gear, power output center are taken turns.
Described planetary gear mechanism; during normal operation; power is by power input centre wheel input; because motionless internal gear is fixed by procapsid; input centre wheel engages with front end planetary gear and transfers power on planet carrier; planet carrier transfers power to end planetary gear, because movable internal gear is protected pin to fix, power is delivered to power output center wheel by end planetary gear and realizes the transmission of moment of torsion.
Described planetary gear mechanism, employing becomes design of gears and meets the radial deflection compensated when installing, can also the radial deflection of dynamic compensation two axle in running, the connection transmission of shaft coupling can well be realized, be equivalent to output center wheel fixed when running occurs shock loading or overload, movable internal gear will produce moment of torsion, when the moment of torsion produced is more than when presetting the breakdown strength protecting pin, protection pin will be cut off destruction, movable internal gear will start to rotate the effect playing overload protection, when solving overload problem, the protection pin destroyed is taken out and reinserts new protection pin, shaft coupling just can run well, this shaft coupling recoverability is good.
Described power input centre wheel and power output center are taken turns with modulus with the number of teeth.
Described front end planetary gear and end planetary gear with modulus with the number of teeth.
Described motionless internal gear and dynamic movable internal gear with modulus with the number of teeth.
Described procapsid is to be connected with the external world and the most fixed.
Compared with existing shaft coupling, the invention have the benefit that
Radial deflection when utilizing planetary displacement to make shaft coupling can compensate installation as far as possible, can also compensate for the radial deflection of two connecting shafts dynamically changed in operation process.It is good that Gear Planet Transmission all carries characteristic, can bear bigger moment of torsion, it is achieved high pulling torque stably transmits.And protecting pin fracture to play overload protection when by shock loading or overload to be acted on, after solving overload problem, the protection pin taking-up destroyed is reinserted new protection pin, shaft coupling just can run well, and this shaft coupling recoverability is good.

Detailed description of the invention
The present invention will be further described below:
In conjunction with Fig. 1, Fig. 2, Fig. 3: plant the Planetary Gear Transmission shaft coupling with overload protection, including procapsid 10, back casing 8, protection pin 9, planetary gear mechanism.
Planetary gear mechanism includes that power inputs centre wheel 1, front end planetary gear 2, motionless internal gear 3, planet carrier 6, end planetary gear 5, movable internal gear 4, power output inner gear 7.During normal operation; power is inputted by power input centre wheel 1; because motionless internal gear 3 is fixed by procapsid 10; input centre wheel 1 engages with front end planetary gear 2 and transfers power on planet carrier 6; planet carrier 6 transfers power to end planetary gear 5; because movable internal gear 4 is fixed on back casing 8 by protection pin 9, power is delivered to power output center wheel 7 by end planetary gear 5 and realizes the transmission of moment of torsion.
When there is shock loading or overload; be equivalent to output center wheel 7 maintained static; movable internal gear 4 will produce moment of torsion; when the moment of torsion produced is more than when presetting the breakdown strength protecting pin 9; protection pin will be cut off destruction, and movable internal gear 4 will start to rotate the effect playing overload protection.
When solving overload problem, being taken out by the protection pin 9 destroyed and reinsert new protection pin 9, shaft coupling just can run well.
