Abstract

The utility model relates to a grease hole structure of a bend pulley bearing chamber. The key points are as follow: a threaded grease hole is arranged at the appropriate position of the outer cover of the bearing chamber; grease is injected into the bearing chamber through the hole by a grease gun, to keep a bearing to be well lubricated; after the grease is injected, a plug is used to block the grease hole, so as to prevent foreign substances from entering into the bearing chamber and prevent the grease in the bearing chamber from flowing out. The grease hole is easy to be processed and convenient to be operated, and solves the problems that in the traditional design schemes, the manufacturing process of the grease holes is quite difficult, which brings certain damage to the strength of shafts.

Description

A kind of changing orientation drum shaft holds chamber oil hole structure

One, technical field

The utility model relates to the new construction that a kind of belt transporter changing orientation drum shaft holds the chamber oil hole.

Two, background technology

Built in type belt feeder cylinder is meant that bearing, bearing seat are arranged in roller tube inside, and drum shaft is placed on two fixedly on the axle bed during work, and drum shaft does not change, the cylinder that cylindrical shell sways.Such cylinder all belongs to the changed course cylinder, and diameter is generally all at φ below 500, and this class cylinder uses on the mine leather belt machine in a large number.

Cylinder when work otherwise the rotation that stops are normally used for keeping bearing, must refuel to bearing (usually all grease up), make bearing keep lubricated, to reduce friction, avoid causing bearing failure because of frictional heating.Traditional oiling mode is: respectively process an axial deep hole in center, drum shaft two ends, in bearing chamber upper edge, the appropriate location axle of drum shaft radially make a call to a hole, make it to connect with axial hole.Like this, just can make bearing often keep good lubricating status when needing by oil hole oiling in bearing chamber of axle head.But this oil hole structure is relatively more difficult in the axial deep hole processing of axle, moreover the structure that processing is axial on axle, radial hole all can destroy axle influences its intensity.

Three, summary of the invention

The technical problems to be solved in the utility model is: design the new construction that a kind of changing orientation drum shaft holds the chamber oil hole, to overcome the problem that prior art exists.

The technical scheme that solution the utility model technical matters is taked is: hold the outdoor threaded oil hole of processing that covers at changing orientation drum shaft, a plug is arranged on the oil hole.

Good effect of the present utility model is: processing technology is simple, and is easy to operate; It is bigger to have solved traditional design scheme oil hole manufacture craft difficulty, and the intensity of axle is caused the problem of destruction to a certain degree.

Four, description of drawings

The changed course cylinder scheme drawing that has new oil hole structure

Five, the specific embodiment

As shown in drawings, threaded oil hole 2 at a M6-1 2 of bearing chamber enclosing cover 3 appropriate locations processing, can use grease compressor grease to bearing chamber 4 filling butter by this hole, keep bearing 5 lubricated good, with a plug 1 oil hole 2 is blocked up after the oiling, prevent that foreign matter from entering and bearing chamber 4 interior butter flow out.

Claims (1)

1, a kind of changing orientation drum shaft holds chamber oil hole structure, it is characterized in that: hold outdoor lid (3) at changing orientation drum shaft and go up a processing threaded oil hole (2), a plug (1) is arranged on the screw thread oil hole (2).
