Background technique
In various kinds of equipment especially high-speed overload speed reducer in metallurgy industry, gearshift feature is revolving speed height, is changed
Gear pushing block is easy to happen abrasion and fail, and the power shift gear in heavy-load gear box is self-possessed heavier, and shift that gear-box is matched is oily/
Cylinder, thrust is larger, be easy to cause pushing block to hit in shift process damaged, gently then needs to shut down replacement spare part, weight then breakage zero
Part is fallen into meshing gear, causes gear of serious failure, and significant trouble occurs for gear-box, and the invention can effectively solve the problem that this is asked
Topic.
Summary of the invention
Goal of the invention: lead to pushing block quick abrasion of shifting gears to solve high-speed rotating ring gear, impact and lead in shift process
Cause is moved back hits the problem of splitting fastly, and the present invention provides a kind of reduction gearbox high-speed gear-shifting mechanism.
Technical solution: a kind of reduction gearbox high-speed gear-shifting mechanism, including the small axis of shift, stop pad, nut, spacer ring, zanjon axis
It holds, babbit, supporting element and hose coupling, the small axis of the shift are fixed in reduction gearbox by nut, control shift fork reality
The switching of ring gear or outer gear ring in existing power shift gear；It is equipped with supporting element inside the small axis of shift, described supporting element one end is set
There is hose coupling, one end is equipped with oil-through hole, and lubricating oil is transferred to the inside of spherical groove on the inside of zanjon bearing by the oil-through hole；Institute
The contact site for stating zanjon bearing and small axis of shifting gears is equipped with spacer ring, and outer ring pours babbit.
Further, it is equipped with fuel feed hole and pipeline road inside the small axis of shift, it is by pipeline road that lubricating oil is defeated
It is sent to zanjon Bearing inner；
Further, the specific location of the fuel feed hole and pipeline road includes the supporting element being arranged in inside small axis of shifting gears
In.
It further, is hollow pipeline inside the support rod.
Further, the nut is round nut, and the mounting portion of the nut and small axis of shifting gears is equipped with stop pad.
Further, the lubrication oil is thin oil.
The small axis outer circle of shift of the present invention installs deep groove ball bearing, deep groove ball bearing outer ring babbitting and changes
It keeps off in small axis and opens up oil inlet pipe, hose is installed by hose coupling, connects thin oil lubricant shift assembly.
The utility model has the advantages that compared with prior art, the present invention is by the way that selector fork to be fixed on the small axis of shift, and it is small to shift gears
The outer circle installation zanjon bearing of axis is, it can be achieved that shift fork pushing block and shift ring gear are in rolling contact, reduction abrasion loss；Another party
Face, the present invention in deep groove ball bearing outer ring babbitting, the impact in shift process for bearing can be buffered, so that axis
The probability of damage held substantially reduces.
Detailed description of the invention
Fig. 1 is structural scheme of mechanism of the invention；
