Abstract
The utility model is disclosed to be used for the multiple bearing pull bar of coal winning machine clutch, including the spindle nose for being coaxially disposed and being sequentially connected, collar, axle body, positioning step and axle journal, bearing group and location nut are respectively sleeved on axle journal, bearing group is located between positioning step and location nut, bearing group includes being provided with distance set between more than two bearings, two adjacent bearings.Multiple bearing pull bar of the present utility model for coal winning machine clutch is solved present in prior art in production process the problem of clutch pull rod bearing frequent breakage.The production efficiency of equipment is improved while material consumption is reduced, while alleviating the labor intensity of maintenance personal.In addition, the multiple bearing Tiebar structure is simple, low cost, easily operation, it is easy to promote.
Description
Technical field
The utility model belongs to coal-winning machine field of mechanical technique, and in particular to a kind of multiple bearing for coal winning machine clutch
Pull bar.
Background technology
In coal production, the normally operation of whole mine electromechanical equipment is most important, and some link goes wrong all
It is likely to cause the stopping production of mine.Therefore in pit mining and produced, mechanical ＆ electrical technology innovation is most important.In mine just
Often coal-winning machine plays vital effect in production, and the clutch of rocker arm of coal mining machine cutting motor mainly passes through pull bar
The relative position for adjusting torque axis carrys out the power transmission of " dividing " " conjunction " cutting motor and rocking arm reduction box, and this clutch, which passes through, to be installed
A dish axle in handle bar shaft end, which is held, couples operation with torque axis, and this dish axle, which is held, mainly support torque axis in operation axially
Do not changed with radial position, it is ensured that cutting motor is smoothly delivered to power in rocking arm reduction box by torque axis.
In actual moving process, bearing on pull bar is larger due to radial force, causes the load of single-deck bearing excessive,
So that bearing frequent breakage, changes a disk for average every 5 days, bearing process is changed every time needs 40 minutes, disappears to colliery material
Consumption and normal production cause very big loss.
Utility model content
The purpose of this utility model is to provide a kind of multiple bearing pull bar for coal winning machine clutch, solves existing skill
Clutch pull rod single-bearing load present in art is excessive and the problem of frequent breakage.
The technical scheme that the utility model is used is：Set for the multiple bearing pull bar of coal winning machine clutch, including coaxially
Bearing group and location nut are respectively sleeved on spindle nose, collar, axle body, positioning step and the axle journal put and be sequentially connected, axle journal,
Bearing group is located between positioning step and location nut, and bearing group is included between more than two bearings, two adjacent bearings
It is provided with distance set.
The characteristics of the utility model, also resides in,
Connected mode between axle journal and location nut is to be threadedly coupled.
The beneficial effects of the utility model are：Multiple bearing pull bar of the present utility model for coal winning machine clutch, passes through
Practice examining on coal-winning machine, using good, reaches the effect got twice the result with half the effort, is improved while reducing material consumption
The production efficiency of equipment, while alleviating the labor intensity of maintenance personal.The repair time of 240 minutes can be monthly saved, can be many
Producing raw coal output increases by 1967 tons.In addition, the duplex bearing Tiebar structure is simple, low cost, easily operation, it is easy to promote.
Brief description of the drawings
Fig. 1 is the structural representation of the multiple bearing pull bar of the present utility model for coal winning machine clutch.
In figure, 1. spindle noses, 2. collars, 3. axle bodies, 4. positioning steps, 5. axle journals, 6. location nuts, 7. bearings, 8. distances
Set.
Embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
The utility model provides a kind of multiaxis bearing apparatus based on coal winning machine clutch pull bar, as shown in figure 1, including same
Bearing group is respectively sleeved on spindle nose 1, collar 2, axle body 3, positioning step 4 and axle journal 5 that axle sets and is sequentially connected, axle journal 5
With location nut 6, bearing group is located between positioning step 4 and location nut 6, and bearing group includes more than two bearings 7, adjacent
Two bearings 7 between be provided with distance set 8.
Connected mode between axle journal 5 and location nut 6 is to be threadedly coupled.
In use, the carrying stress of pull rod shaft can effectively be strengthened by holding 7 using two dish axles, and two dish axles hold between 7 away from
From set 8 be according to the end-play scope of bearing 7 set, distance set 8 thickness be 3mm, can effectively prevent two dish axles hold 7
Interfere, fastened afterwards with end nut in running, prevent that distance set 8 from running out bearing inner sleeve, adopted in pull bar shaft end
With the setting of nut screw connection screw thread, primarily to facilitate the socket of bearing 7, while nut coordinates with positioning step 4, Ke Yijin
Axial movement of the one step limited bearing 7 in pull rod shaft.In actual use, can also be according to the carrying stress feelings of axle
Condition, the quantity of appropriate increase bearing 7, to reach more preferable supporting effect, this multiaxis bearing apparatus can support torque axis in operation
Middle axial direction and radial position are not changed, it is ensured that power is smoothly delivered to rocking arm reduction box by cutting motor by torque axis
In.
Multiple bearing pull bar of the present utility model for coal winning machine clutch, by the practice test on coal-winning machine, makes
With good, the effect got twice the result with half the effort is reached, the equipment operation and maintenance cycle is extended, material consumption is reduced while improving
The production efficiency of equipment, while alleviating the labor intensity of maintenance personal.The repair time of 240 minutes can be monthly saved, can be many
Producing raw coal output increases by 1967 tons.In addition, the multiple bearing Tiebar structure is simple, low cost, easily operation, it is easy to promote.
