Description
Technical field
The invention belongs to Worm and Worm Gear Driving field, more particularly to a kind of list worm screw many worm gears of input that are capable of achieving are exported simultaneously
Worm and Worm Gear Driving device.
Background technology
Worm and Worm Gear Driving device is mainly used to transmit between two axles of spatial intersecting as one of gear-driven type
Power and motion, due to its compact conformation, transmission speed ratio is big, noise is small, worm gear output torque is big the features such as and obtain extensively
Using.But, existing worm gearing generally uses the form of single worm screw and single worm-drive, accordingly, it is difficult to
Meet be driven to many workloads simultaneously the need for.
Chinese patent CN 98112854.8 discloses a kind of cylindrical worm double-nodal point side set double worm gear driving system, according to
Working pitch point can form the principle of displacement Worm and Worm Gear Driving in the movement of the circumferencial direction of worm screw, symmetrical in a cylindrical worm
Two nodes of side at be symmetrical arranged two worm gears.Although this kind of transmission system overcomes a worm screw and a worm gear
Into cylindrical worm worm gear system in engagement contact tooth is few and Lubrication Angle is small shortcoming, bearing capacity and transmission efficiency
Increase, but its weak point is：The composite curve radius between the flank of tooth that are meshed are smaller, thus bearing capacity is significantly smaller than commonly
Double enveloped hourglass worm drives (common double enveloped hourglass worm drives are shown in Fig. 6)；One worm screw and two worm gear combinations, it is difficult to meet same
When more than two workloads are driven the need for.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, there is provided single many worm gear end face mesh gears of worm screw,
To realize being driven many workloads simultaneously, and meet the requirement of heavy load transmission.
The many worm gear end face mesh gears of single worm screw of the present invention, there is following two structure types, but they belong to
One total inventive concept.
First, the first structure type
The many worm gear end face mesh gears of single worm screw of the first structure type, including a worm screw and worm combination
Power input shaft, 2~4 worm gears and the power output shaft that is combined with each worm gear respectively, the worm screw is double enveloping end
Worm screw is engaged in face, and the engaging tooth of double enveloping end face engagement worm screw is arranged in the left end face and its right end face of worm screw, respectively
Worm gear engages the upper left side field of conjugate action, the lower left side field of conjugate action, the upper right side field of conjugate action, the lower right side of worm screw with double enveloping end face respectively
Field of conjugate action engagement in the field of conjugate action.
In many worm gear end face mesh gears of single worm screw of above-mentioned the first structure type, the double enveloping end face is nibbled
The worm gear that the left end face for closing worm screw is respectively adopted the different numbers of teeth from its right end face carries out envelope, has two side ends face different
Gearratio.
In many worm gear end face mesh gears of single worm screw of above-mentioned the first structure type, the quantity of the worm gear is preferred
2 or 4, to arrange worm wheel symmetrical, reduce the axial force of worm screw so that transmission is more steady.
2nd, second structure type
The many worm gear end face mesh gears of single worm screw of second structure type include a worm screw and worm combination
Power input shaft, 2 worm gears and the power output shaft for being combined with each worm gear respectively, the worm screw are that double enveloping end face engages snail
Bar, the engaging tooth of double enveloping end face engagement worm screw is arranged in the left end face of worm screw or its right end face, each worm gear difference
Engaged with double enveloping end face in the upper left side field of conjugate action, the lower left side field of conjugate action of worm screw a field of conjugate action engagement, or respectively with
Field of conjugate action engagement in the upper right side field of conjugate action, the lower right side field of conjugate action of double enveloping end face engagement worm screw.
The invention has the advantages that：
1st, many worm gear end face mesh gears of single worm screw of the present invention drive 2~4 worm gears by a worm screw,
Not only can simultaneously realize the output of many worm gears, meet be driven to many workloads simultaneously the need for, and it is simple structure, tight
Gather；When worm gear is 2 or 4, transmission is more steady.
2nd, due to the worm screw in single many worm gear end face mesh gears of worm screw of the present invention for double enveloping end face is nibbled
Worm screw is closed, with worm gear by the way of end face is engaged, thus in the case where total number of teeth in engagement is not changed, common anchor ring snail is overcome
The problem that bar throat rigidity is not enough, improves bearing capacity, can meet the requirement of heavy load transmission.
3rd, due to the worm screw in single many worm gear end face mesh gears of worm screw of the present invention for double enveloping end face is nibbled
Close and engaging tooth can be set on worm screw, and left end face and its right end face, thus when the left end face of worm screw is adopted with its right end face
Envelope is carried out respectively with the worm gear of the different numbers of teeth, then can make two side ends face that there are different gearratios, be conducive to the tune of gearratio
It is whole.
4th, many worm gear end face mesh gears of single worm screw of the present invention are in field of photovoltaic power generation, large-scale astronomical telescope
Field, radar, cannon and engineering machine machinery claw tool field are respectively provided with wide application prospect.
