Abstract

The utility model belongs to mechanical field, relates to a kind of electric dipper slewing mechanism vertical shaft lower bearing block plate.The utility model comprises block plate body, and described block plate body is circular, and block plate body card central authorities are provided with axis hole, and block plate body card is evenly provided with oil-through hole around axis hole.Block plate body of the present utility model adopts round structure, can effectively to lower bearing effective location, the problem that the traditional cone back-up ring solved not easily is located, whole assembly is caused to install because lower bearing outer ring is crooked when preventing Overhaul site from rotary vertical shaft assembly being installed, greatly save the repair time, improve power shovel operating efficiency.

Description

A kind of electric dipper slewing mechanism vertical shaft lower bearing block plate
Technical field
The utility model belongs to mechanical field, relates to a kind of electric dipper slewing mechanism vertical shaft lower bearing block plate.
Background technique
Electric dipper slewing reducing gear is the basic system of electric dipper slewing operation, and electric dipper slewing reducing gear is a 2-level reducer, and its critical piece is exactly transmission shaft and driving gear; In reducing gear, rotary vertical shaft assembly is become by rotary vertical shaft, up and down rotary vertical shaft bearing, lower bearing positioning device and other enclosure group, when rotary vertical shaft assembly is installed in reducer shell, because traditional lower bearing back-up ring is taper structure, its structural type cannot carry out effective location to lower bearing, therefore once slightly deflection in rotary vertical shaft assembly decentralization process, the outer ring of lower bearing always occurs crooked and stuck with the decelerator body collision rift, thus causes rotary vertical shaft assembly to install.
Model utility content
The purpose of this utility model be for prior art Problems existing provide a kind of can to the block plate of lower bearing effective location.
A kind of electric dipper slewing mechanism vertical shaft lower bearing block plate, comprises block plate body, it is characterized in that: described block plate body is for circular, and block plate body card central authorities are provided with axis hole, and block plate body card is evenly provided with oil-through hole around axis hole;
Further, described block plate body edges is provided with gear oil groove, is provided with Sealing in gear oil groove;
Further, described oil-through hole quantity is 6.
The utility model has following beneficial effect:
Block plate body of the present utility model adopts round structure, can effectively to lower bearing effective location, solve the problem that traditional cone back-up ring is not easily located, whole assembly is caused to install because lower bearing outer ring is crooked when preventing Overhaul site from rotary vertical shaft assembly being installed, greatly save the repair time, improve power shovel operating efficiency; 6 oil-through holes of evenly arranging can allow lubricant oil effectively arrive bearing portions; Gear oil groove and the interior Sealing installed of gear oil groove prevent lubricant oil from being flowed into by block plate body edges and the decelerator body inwall and being caused the leakage of oil of vertical shaft bottom.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the plan view of Fig. 1.
Embodiment
A kind of electric dipper slewing mechanism vertical shaft lower bearing block plate as depicted in figs. 1 and 2, comprise block plate body 1, described block plate body 1 is circular, block plate body 1 card central authorities are provided with axis hole 2, block plate body 1 card is evenly provided with 6 oil-through holes 3 around axis hole 2, described block plate body 1 edge is provided with gear oil groove 4, is provided with Sealing in gear oil groove 4.
Block plate body 1 of the present utility model is between lower bearing and the shaft shoulder of rotary vertical shaft, and block plate body 1 can carry out effective location to lower bearing, prevents outer ring and the decelerator body collision of lower bearing; Oil filling mechanism lubricates lower bearing, lubricant oil arrives bearing portions by 6 oil-through holes 3 in block plate body 1 card and lubricates, and gear oil groove 4 and the interior Sealing installed of gear oil groove 4 prevent lubricant oil from being flowed into by block plate body 1 edge and the decelerator body inwall and being caused the leakage of oil of vertical shaft bottom.
