Abstract
This utility model relates to a kind of agricultural machinery sealer with assembled.This device includes bearing block, bearing, oil sealing, rotary shaft.Described oil sealing is installed on the rotary shaft, and described bearing is installed on the rotary shaft, and described bearing block coordinates with bearing, oil sealing, is machined with trapezoidal or rectangular thread in the rotary shaft installing oil sealing end side.Prominent effect of the present utility model is: rotary shaft screw thread when rotated and water relative motion, and water is constantly screwed out in rotary course by screw thread, thus stops water to enter bearing side, forms movable sealing.When axle is static, oil sealing can stop the entrance of water completely.No matter this device can effectively prevent the entrance of water and mud in axle duty or resting state.
Description
Technical field
This utility model relates to a kind of agricultural machinery sealer with assembled.
Background technology
Various agricultural machinery, because working in the medium having dust, muddy water, can enter bearing because of water, silt particle and accelerate axle
Hold abrasion, corrosion, cause bearing damage, cause machinery to operate.Current sealing structure has: contact oil seal seals, knot
Structure is simple but sealing effectiveness is poor, and the abrasion caused because of silt particle causes oil sealing and axle, bearing damage；Non-contacting seal+oil sealing is close
Envelope, structure is complex and silt particle still can invade oil sealing and cause initial failure；Combined grease seal (i.e. transport once by oil sealing self
Dynamic pair) silt particle still can invade bearing after relatively costly and abrasion；Other seals because of structure and cost reason not at agricultural machinery
Middle application.
Summary of the invention
The purpose of this utility model is the problem existed for background technology, design a kind of simple in construction, practicality, low cost
Agricultural machinery sealer with assembled.
The technical solution of the utility model is: a kind of agricultural machinery sealer with assembled, including bearing block, bearing, oil
Envelope, rotary shaft；Described bearing is installed on the rotary shaft, and described oil sealing is close to bearing side and is installed on the rotary shaft；Described
Bearing block closely cooperate with bearing, oil sealing and be integrated, the rotary shaft outside oil sealing is machined with external screw thread.
The external screw thread that this utility model is processed on the rotary shaft is trapezoidal thread or rectangular thread.
Oil sealing described in the utility model is two pieces, and two pieces is mounted side by side.
The inner hole rotary shaft of oil sealing described in the utility model, cylindrical fitted shaft bearing.
Sealing device described in the utility model is applied on the tool roller axis of paddy field tillage cultivator.
Prominent effect of the present utility model is: rotary shaft screw thread when rotated and water relative motion, screw thread is at rotary course
In constantly water is screwed out, stop from face water to enter bearing side, form movable sealing.When axle is static, and oil sealing can stop completely
The entrance of water.No matter this device can effectively prevent the entrance of water and mud in axle duty or resting state.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
In figure: 1, bearing block；2, bearing；3, oil sealing；4, rotary shaft；5, external screw thread.
Detailed description of the invention
As it is shown in figure 1, this utility model is applied on the tool roller axis of paddy field tillage cultivator.This device include bearing block, bearing,
Oil sealing, rotary shaft.Described oil sealing is installed on the rotary shaft, and described bearing is installed on the rotary shaft, described bearing block with
Bearing, oil sealing coordinate, and are machined with trapezoidal thread or rectangular thread in the rotary shaft installing oil sealing side.Of the present utility model prominent
Going out effect is: rotary shaft screw thread when rotated and water relative motion, and water is constantly screwed out in rotary course, thus stops by screw thread
Water enters bearing side, forms movable sealing.When axle is static, oil sealing can stop the entrance of water completely.No matter this device is at axle
Duty or resting state can effectively prevent the entrance of water and mud.
Enforcement described in the utility model is the description to preferred embodiment of the present utility model, not new to this practicality
The scope and spirit of type are defined, without departing from the various modification on the premise of this utility model design philosophy and improve all should
Fall into protection domain of the present utility model.
