Abstract
The utility model provides an on axle journal (5) that rotary tiller shaft sealed bearing seat, its bearing pedestal (2) and bearing cap (8) are connected with bolt (1), establish two oil blanket (3) in bearing pedestal and the arbor department of meeting, establish one outer oil blanket (6) in bearing pedestal (2) outside, and one recess (7) are established in the outside of outer oil blanket, and buckle outside on the oil blanket dust cover (4), and its one end imbeds foretell recess (7), and other end company is at the arbor. This device has installed an oil blanket again additional in bearing frame outside, has welded the dust cover of the tight size of a process processing simultaneously outside again, and this cover size is tight, and the tight closing cap of oil blanket with arbor bearing frame outside has further reduced the damage of dust to the oil blanket. This device is two operation after dates in 1 year, and the rotary tiller shaft bearing still as new, does not have any damage, and the arbor rotates steadily as before.
Description
Technical field
The utility model relates to a kind of bearing block, is the bearing block of the good seal performance of rotary tiller shaft specifically.
Background technology
Rotary tillage stubble-cutting machine class agricultural tool develops into today in updating, improving, but the sealing problem of cutter shaft bearing block, be the difficult problem perplexing each manufacturing enterprise always.Bearing block by time an oil sealing, change two oil sealing sealings gradually into, welded again the dust cover that a thin iron is stamped to form afterwards outside, due to cutter shaft almost operation in soil, although installed two oil sealings inside cutter shaft bearing block, the soil of outside still can enter in bearing by gap gradually, and general facility are after one to two operational period, cutter shaft bearing just cannot rotate because of the grinding of dirt bits, must change.Also have and change bearing user not in time, make spindle nose grind groove, cause whole cutter shaft all will change.A seal parts is not tight, brings very large loss to individual dealer of agricultural machines.
Summary of the invention
The purpose of this utility model is to provide a kind of rotary tiller shaft sealed bearing, and its sealing is tight, extends the service life of cutter shaft bearing, reduces rotary tillage stubble-cutting machine operating cost.
The technical solution of the utility model is as follows:
A kind of rotary tiller shaft sealed bearing, bearing seat is connected with bolt with bearing cap, two oil sealings are established at bearing seat and cutter shaft joint, an outer oil seal is established outside bearing seat, a groove is established in the outside of outer oil seal, dust cover is buckled on outer oil seal, and its one end embeds above-mentioned groove, and the other end is connected on the axle journal of cutter shaft.
Above-mentioned dust cover is made by thick-walled pipe.
The utility model has the advantage of: 1, this device has installed again an oil sealing additional outside bearing block, welded again the dust cover of a tight dimensioned of process outside simultaneously, be embedded in the groove of oil sealing outboard shafts bearing, dust cover has been made into by thick-walled pipe as material by original thin iron punching press.Each several part size is all formed by lathe process.This cover size is tight, by tight for the oil sealing outside cutter shaft bearing block capping, further reduces the damage of dust to oil sealing.The bearing of sealing structure, in 1 year after two operational periods, still as new, without any damage, cutter shaft stability of rotation as before.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment cross-sectional view.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Can be seen by Fig. 1, this rotary tiller shaft sealed bearing, bearing seat 2 is connected with bolt 1 with bearing cap 8, two oil sealings 3 are established at bearing seat and cutter shaft joint, outside bearing seat, establish an outer oil seal 6, a groove 7 is established in the outside of outer oil seal, and dust cover 4 is buckled on outer oil seal, its one end embeds above-mentioned groove 7, and the other end is connected on the axle journal 5 of cutter shaft.Above-mentioned dust cover 4 is made by thick-walled pipe.
Claims (2)
1. a rotary tiller shaft sealed bearing, its bearing seat (2) is connected with bolt (1) with bearing cap (8), two oil sealings (3) are established at bearing seat and cutter shaft joint, it is characterized in that: establish an outer oil seal (6) in bearing seat (2) outside, a groove (7) is established in the outside of outer oil seal, dust cover (4) is buckled on outer oil seal, its one end embeds above-mentioned groove (7), and the other end is connected on the axle journal (5) of cutter shaft.
