Important parameters of a transmission worm, a helical gear and the lead screw of the speed reducing mechanism are studied, the transmission worm, the helical gear and the lead screw are machined and assembled according to set parameter requirements, and the lead screw transmission device which hardly produces noise and has the one-way braking function is obtained.
Description
Technical field
The present invention relates to transmission device, specifically refer to a kind of spindle gear with one-way brake function.
Background technique
Line handspike mechanism realizes to-and-fro motion by the corresponding actuator drives push rod of motor-driven.Can be used for using as executive component in simple or complicated separately technological process.Be widely used in the various fields such as fitness equipments, medical apparatus, furniture.
Most of massage chair installs corresponding line handspike mechanism exactly on its node, under the action of line handspike mechanism, the corresponding site of massage chair is controlled and is realized massage effect.The form of the transmission device of line handspike mechanism has a lot, adds driving mechanism, reduction gears mechanism adds screw mandrel or nut transmission mechanism etc. such as: gear reduction unit adds gear mechanism, tooth bar.Now generally adopt reduction gears mechanism to add screw mandrel for the transmission device of the line handspike mechanism on massage chair.
Be not subjected to displacement when ensureing that the push rod of line handspike mechanism of massage chair can accurately remain on arbitrary position or move to specified position, must realize by the one-way brake of its transmission device.At present, be generally on transmission device, to set up corresponding braking device to realize one-way brake.The compactedness of transmission device is the Main Basis that massage chair transmission device is selected, and adds braking device and has not only reduced the original compactedness of transmission device and also increased cost of production simultaneously.As everyone knows, along with the minimizing of screw lead, its self-lock ability can be increasing, and therefore, a lot of researchers make great efforts to attempt realizing by the helical pitch of reduction screw mandrel the one-way brake of transmission device always.In the time that the helical pitch of screw mandrel is down to 3mm, its self-lock ability is enough realized one-way brake in massage chair.But while being down to 3mm due to the helical pitch of screw mandrel, when transmission device operation, can produce very large noise, the spindle gear that therefore helical pitch is 3mm is difficult to be used in massage chair, and the screw mandrel being used in massage chair is at present all generally the screw mandrel of helical pitch 4mm.
Summary of the invention
The invention reside in a kind of screw lead is provided is the spindle gear with one-way brake function of 3mm, its compact structure, and can realize low noise operation.
