Fig. 2 is prior art milling train transmission structures schematic diagram;
In figure, be labeled as: milling train adapter sleeve 1, the first connector 2, barreled tooth flank cover A3, barreled tooth flank A4, bracket 5, barreled tooth flank cover B6, barreled tooth flank B7, the second connector 8, barreled tooth flank cover C9, bearing block 10, barreled tooth flank C11, the 3rd connector 12, half gear coupling 13, reductor adapter sleeve 14.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
Milling train transmission device comprises milling train adapter sleeve 1, reductor adapter sleeve 14 and bindiny mechanism, and milling train adapter sleeve 1 is connected by bindiny mechanism with reductor adapter sleeve 14; Bindiny mechanism comprises the first connector 2, the second connector 8, the 3rd connector 12, half gear coupling 13, bracket 5 and bearing block 10; Milling train adapter sleeve 10, the first connector 2, the second connector 8, the 3rd connector 12 set gradually and all connect by barreled tooth flank structure, and the 3rd connector 12 is connected with reductor adapter sleeve 14 by half gear coupling 13; Bracket 5 is by its inner bearings the first connector 2 of installing; Bearing block 10 is by its inner bearings the 3rd connector 12 of installing.Milling train adapter sleeve 1 connects roll, and reductor adapter sleeve 14 connects reductor.
Barreled tooth flank structure refers to by barreled tooth flank cover and is sleeved on and in barreled tooth flank, connects and the mechanism of transmitting torque.Barreled tooth flank structure can be barreled tooth flank shaft joint (for prior art), i.e. outsourcing barreled tooth flank shaft joint is separately positioned between milling train adapter sleeve 10, the first connector 2, the second connector 8, the 3rd connector 12, but parts are more like this, complex structure.The present invention recommends set-up mode as follows: milling train adapter sleeve 1 outer setting has barreled tooth flank A4, and the first connector 2 is provided with barreled tooth flank cover A3 near milling train adapter sleeve 1 one end, and barreled tooth flank cover A3 is set on barreled tooth flank A4.The first connector 2 is provided with barreled tooth flank cover B6 away from milling train adapter sleeve 1 one end, and the second connector 8 is provided with barreled tooth flank B7 near milling train adapter sleeve 1 one end, and barreled tooth flank cover B6 is set on barreled tooth flank B7.The second connector 8 is provided with barreled tooth flank C11 away from milling train adapter sleeve 1 one end, and the 3rd connector 12 is provided with barreled tooth flank cover C9 near milling train adapter sleeve 1 one end, and barreled tooth flank cover C9 is set on barreled tooth flank C11.Each barreled tooth flank is identical with the profile of tooth of standard barreled tooth flank shaft joint with the profile of tooth of barreled tooth flank cover.Half gear coupling 13 can buy on market.
Crowned tooth machanism allows corner little, allowing pivot angle is 1～3 °, and therefore, the free degree is less, there is certain rigidity, meanwhile, this structure length is little, from heavy and light, this series structure feature, the deviation value that has objectively limited the geometric center lines of its running center line and axle can not be very large, thereby controlled it to the centrifugal impact force of bracket within the specific limits, the destructiveness that unlikely generation is large.And this corner can meet the variation needs of roll centre-to-centre spacing as calculated.Barreled tooth flank and barreled tooth flank cover can relatively move simultaneously, to regulate the length of whole milling train transmission device in less scope.
