Abstract
A bevel gear double split flow three-stage standing speed reducer is characterized in that: a parallel axis driven gear (6) simultaneously meshes with two parallel axis driving gears (5, 5') which are respectively arranged on two parallel axes, each parallel axis is sleeved by a driven bevel gear (4 or 4'), the two driven bevel gears (4, 4') respectively mesh with two symmetric driving bevel gears (3,3') which are respectively driven by two pairs of split flow gears (1, 1', 2, 2'). The utility model distributes power to the two pairs of bevel gears through the two pairs of split flow gears, thereby reaching the aims of reducing the size of the bevel gears, improving gear working accuracy and shortening gear manufacture period, and accordingly meeting the requirements of high-power standing roller grinding and reducing manufacture cost.
Description
One, technical field:
The utility model relates to a kind of retarder, specifically, is a kind of three grades of gearing vertical retarders of bevel gear double split flow that are applicable to that the building material industry cement production line uses.
Two, background technique:
At present, building material industry cement production line scale is increasing, and the raw grinding major part all adopts energy-saving and cost-reducing vertical roller grinder, and its retarder mostly is bevel gear-planet double reduction transmission or bevel gear-parallel axes-three grades of transmissions of planet.The retarder transmitted power of two-stage transmission is restricted, and velocity ratio is little, does not satisfy high-power, big speed ratio requirement.If will increase the transmitted power and the velocity ratio of retarder, just must increase centre distance, therefore, the diameter of gear causes that with regard to corresponding increase the volume of retarder increases, weight increases.The retarder of three grades of transmissions can solve requirement high-power, big speed ratio, but its important helical bevel gear size is still bigger.It not only causes the Gear Processing difficulty to increase and precision reduces, finally cause the retarder manufacture cost to increase, and precision reduces, noise is bigger, does not satisfy requirement working life, and this helical bevel gear is big because of size, domestic process equipment can't meet the demands, can only seek help from minority foreign vendor, the requirement of not satisfying progress and reducing cost has seriously hindered the development of national industry.Because of present employed bevel gear-planet double reduction transmission or bevel gear-parallel axes-three grades of problems that transmission is the most basic of planet are by the bevel-gear sett transmission, therefore, increase velocity ratio and transmitted power, just must add the bevel gear wheel size, thereby cause the Gear Processing difficulty to increase and the precision reduction, cost also increases.
Three, model utility content:
The purpose of this utility model provides three grades of gearing vertical retarders of a kind of bevel gear double split flow, drives the drive mechanism that driven gear rotates in the retarder by changing, and it is big to solve existing retarder bevel gear size, the problem that manufacture cost is high.
For reaching above-mentioned purpose, concrete scheme of the present utility model is: design three grades of gearing vertical retarders of a kind of bevel gear double split flow, comprise the drive bevel gear axle, drive bevel gear, driven wheel of differential, driving gear, driven gear, internal tooth casing, sun gear, planet wheel, ring gear, planet wheel shaft, planet carrier, output flange, casing, its main points are: described driven gear meshes with two driving gears simultaneously, these two driving gears are installed in respectively on two parallel axes, all be set with a driven wheel of differential on the every parallel axes, each driven wheel of differential meshes with two symmetrical drive bevel gear respectively, described drive bevel gear is set in an end of drive bevel gear axle, and the other end of this drive bevel gear axle is set with driven shunting gear; Described two drive bevel gear axles are positioned at the both sides of live axle, are set with two active shunt gears at the middle part of this live axle, each active shunt gear respectively with described driven shunting gear engagement.
Described two active shunt gear equal and opposite in directions are spur gear.
Be between the described driven shunting gear, between the described drive bevel gear, between the described driven wheel of differential and between described two driving gears and be symmetrical arranged, and equal and opposite in direction, shape are identical in twos.
Such scheme two pairs of shunting gears in casing drive two drive bevel gear respectively, thereby drive two driven wheels of differential.A parallel axes driving gear respectively is housed respectively on two driven wheel of differential axles, and two parallel-axes gearss mesh with a parallel axes driven gear simultaneously.Sun gear that connects the planetary stage transmission through internal tooth casing of this parallel axes driven gear, sun gear and planet wheel outer gearing, engagement in planet wheel and the ring gear, and through Bearing Installation on planet axis, planet wheel shaft is installed on the planet carrier, and planet carrier links and moment of torsion is exported through bolt and straight pin and output flange.
This shows, the beneficial effects of the utility model are: by two pairs of shunting gears, on power dividing to two pair bevel gear, reach the size that reduces bevel gear, improve the Gear Processing precision, shorten the purpose of bevel gear process-cycle, thereby satisfy the requirement of high-power vertical roller mill, reduced cost of production.
