Abstract
The present invention relates to a kind of centerless grinder gear, including gearbox body, the gear for being fixed on the central fixing axle of gearbox body, being installed on two sets of bearings of fixing axle upper end and being installed on the outside of two sets of bearings, fixing axle is provided with the axle bumper for blocking bearing inner race, and gear top is provided with the step for gear shaft bearing outer-ring.The beneficial effects of the invention are as follows：Fault rate greatly reduces, and has saved cost, improves production efficiency, and easy to maintenance, has reached good effect.
Description
Technical field
The present invention relates to a kind of centerless grinder gear.
Background technology
Centerless grinder is because dieback occurs repeatedly in the gear shaft that a gear of former gear engages or blocks existing
As having had a strong impact on manufacturing schedule and production efficiency, while cause very big waste.The reason for causing to block has：(1) copper sheathing is with consolidating
Dead axle is cooperation, produces sliding friction during rotation, serious wear, causes gap to increase, and concentricity is bad during pinion rotation, production
Raw very big vibration, it is easy to gear shaft dieback.(2) gap that emery wheel abrasive dust is fallen between gear and axle, make rotation dumb,
There is stuck phenomenon.The gear plays a transition role, and what is simultaneously engaged is a gear shaft and a duplicate gear, if top
It is dead that dozen tooth phenomenon just occurs, make gear by different degrees of damage.In addition, the other end of fixing axle is inserted directly into casing,
So block repeatedly, casing can be damaged.
The content of the invention
The technical problem to be solved in the present invention is：Based on above mentioned problem, there is provided a kind of centerless grinder gear.
The technical solution adopted for the present invention to solve the technical problems is：A kind of centerless grinder gear, including speed change
Casing, the fixing axle for being fixed on gearbox body center, it is installed on two sets of bearings of fixing axle upper end and is installed on two sets of axles
The gear in outside is held, fixing axle is provided with the axle bumper for blocking bearing inner race, and gear top is provided with the step for gear shaft bearing outer-ring.
Further, two sets of bearings are 6304 bearings.
Further, the thickness of step is 5mm.
The beneficial effects of the invention are as follows：Fault rate greatly reduces, and has saved cost, improves production efficiency, and repair
It is convenient, reach good effect.
Brief description of the drawings
The present invention is further described below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present invention.
Wherein：1. axle bumper, 2. gears, 3. bearings, 4. fixing axles, 5. gearbox bodys.
Embodiment
Presently in connection with accompanying drawing, the present invention is further illustrated.These accompanying drawings are simplified schematic diagram only with signal side
Formula illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention.
A kind of centerless grinder gear as shown in Figure 1, including gearbox body 5, it is fixed on consolidating for the center of gearbox body 5
Dead axle 4, two sets of bearings 3 for being installed on the upper end of fixing axle 4 and the gear 2 for being installed on the outside of two sets of bearings 3, in fixing axle 4
Provided with the axle bumper 1 for blocking bearing inner race, the top of gear 2 is provided with the step for gear shaft bearing outer-ring.
Two sets of bearings 3 are 6304 bearings.
The thickness of step is 5mm.
Gear top leaves 5mm thickness step and is used for gear shaft bearing outer-ring, and axle bumper is installed in fixing axle and is used for keeping off bearing inner race, this
Sample bearing is just firmly positioned, will not upper and lower play.Because 6304 bearings are the single-row radial ball bearings with dust cap, without load
Heart emery wheel abrasive dust can fall into wherein and influence to run well.During work, the rotation of gear band dynamic bearing was not only steady but also flexible, and
Fixing axle will not wear, and will not also occur dieback phenomenon again.
It is complete by above-mentioned description, relevant staff using the above-mentioned desirable embodiment according to the present invention as enlightenment
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property scope is not limited to the content on specification, it is necessary to determines its technical scope according to right.
