Background technology
The worm and gear transmission is mechanically operated basic part, is to be used for transmitting the motion of space alternating axis and the motion of power, belongs to gear-driven category; Its stable drive, vibration, impact, noise are all very little, and transmission speed ratio is beaten; Of many uses, be mechanically operated a kind of principal mode.In addition, in motion transmission, it has the effect to transmission system upper reaches error convergence, thereby except that the transmission that is widely used in being used as power, is the first-selected parts of the accurate circular division of lathe and precision instrument mechanism always.So domestic and international many enginerring works and applying unit are all paid much attention to research, application and development to the worm and gear transmission.
With normal cylindrical worm gear parafacies ratio; Enveloping worm pair is multiple tooth two-wire contact, flank of tooth induced normal curvature is little, contact stress is little, slide angle is spent (helping the elastohydrodynamic lubrication between the flank of tooth) near 90; Thereby; Bearing capacity is strong, transmission efficiency is high, is widely used in industries such as metallurgy, chemical industry, machinery, boats and ships, military project, mining, building, lifting transportation, power and light industry and machinery.
At present, China enveloping worm pair of just having is mainly by plane first enveloped enveloping worm pair, planar double-enveloping toroid worm gear.Conical surface twice-enveloping enveloping worm pair (comprising two kinds in single conical surface, bipyramid face) and planar double enveloping worm parafacies ratio have the advantages that number of threads is many, gearratio is big, bearing capacity is high.Single conical surface twice-enveloping enveloping worm pair in process, grind a side of worm tooth after, the palpus bistrique overturns or worm screw turns around grinding is carried out in another side, working (machining) efficiency is low, mismachining tolerance is big.Bipyramid face twice-enveloping enveloping worm is in process, and worm gear carries out grinding simultaneously to two sides of worm tooth, thereby manufacturability is better.
Although bipyramid face twice-enveloping enveloping worm pair has above-mentioned advantage; Single domestic correlative study is few, simultaneously, in the world its manufacturing technology is carried out strict blockade on new techniques; Therefore, the process equipment of domestic bipyramid face twice-enveloping enveloping worm is in space state always.The principal element that the restriction enveloping worm pair is applied has two: the one, and the hobboing cutter processing difficulties, the 2nd, enveloping worm pair is very responsive to the sum of errors distortion.
Summary of the invention
The purpose of the utility model is to have the problems referred to above to existing technology, has proposed that a kind of production cost is low, machining accuracy is high, has improved the bipyramid face twice-enveloping enveloping worm seven Shaft and NC Machining Test grinding correction of the flank shape equipment of worm gear pair meshing quality.
The purpose of the utility model can realize through following technical proposal: a kind of bipyramid face twice-enveloping enveloping worm seven Shaft and NC Machining Test grinding correction of the flank shape equipment; Comprise lathe bed; Have on the described lathe bed tailstock and the main spindle box that is used for the clamping workpiece is installed on horizontal guide rail and the described horizontal guide rail; It is characterized in that; Also have on the described lathe bed centralized positioning slide unit that can slide along guide rail is installed on guide rail and the described guide rail of vertical setting; On the described centralized positioning slide unit rotary table is installed and the transverse slide carriage and vertical slide unit that the control emery wheel that distributes laterally reaches length feed is installed on rotary table, be fixed with emery wheel angle controller and dresser on described vertical slide unit.
In above-mentioned bipyramid face twice-enveloping enveloping worm seven Shaft and NC Machining Test grinding correction of the flank shape equipment, the adjustment handle is installed also on the described horizontal guide rail.Can adjust the spacing between tailstock and the main spindle box through the adjustment handle.
Compared with prior art, the emery wheel that this bipyramid face twice-enveloping enveloping worm seven Shaft and NC Machining Test grinding correction of the flank shape equipment utilization face shapes and bipyramid face twice-enveloping enveloping worm are complementary carries out the grinding correction of the flank shape to worm screw, and is simple in structure, easy to operate, is suitable for producing in enormous quantities.
