Abstract
The present invention relates to a kind of vertical tooth shaft gear bits lubrication speed reducers of hanging sleeve, including cabinet, input conical tooth shaft, bevel gear, vertical gear axis, input conical tooth shaft transmission is placed in the bevel gear in cabinet on vertical gear axis, vertical gear axis upper end is supported on the step in bearing holder (housing, cover) through bearing, and bearing set upper side is supported on cabinet through flange and wears connecting bolt encapsulation through boring cover；Vertical gear axis lower end is supported in the supported hole of cabinet through bearing, and the bottom of box above supported hole is equipped with a circle gear bits circle, and gear bits circle internal diameter is greater than supported hole aperture.Its structure is simple, compact, takes into account vertical tooth shaft mounting and adjusting required precision and tooth shaft support mounting, prevents lubrication impurity damage bearing.
Description
Technical field
The present invention relates to a kind of speed reducer, specifically a kind of vertical tooth shaft gear bits lubrication speed reducer of hanging sleeve,.
Background technique
The tooth shaft installation of traditional vertical axis speed reducer is mostly using seam allowance step is reserved on cabinet, by step through bearing branch
Tooth shaft is supportted, but since speed reducer internal tooth shaft gear needs to adjust when engaging installation, it is poor that vertical type square has an Adjustment precision upwards, case
The adjusting that seam allowance step is unable to satisfy low precision is reserved on body, influences Meshing engagement energy；In addition, vertical type speed reducer (change gear) cabinet bottom
Grease relief mouth is arranged in portion, but the particulate contamination as present in lubricating oil, impurity easily enter the branch of bottom with lubricating oil
Bearing is supportted, bearing service life is influenced.
Summary of the invention
It is simple, compact that the present invention provides a kind of structures, takes into account vertical tooth shaft mounting and adjusting required precision and tooth shaft support
Mounting prevents the vertical tooth shaft gear bits lubrication speed reducer of the hanging sleeve of lubrication impurity damage bearing.
The technical solution adopted by the present invention is that: a kind of vertical tooth shaft gear bits lubrication speed reducer of hanging sleeve, including cabinet, input cone
Tooth shaft, bevel gear, vertical gear axis, input conical tooth shaft transmission are placed in the bevel gear in cabinet on vertical gear axis, and feature exists
In: vertical gear axis upper end is supported on the step in bearing holder (housing, cover) through bearing, and bearing set upper side is supported on case through flange
Connecting bolt encapsulation is worn on body and through boring cover；Vertical gear axis lower end is supported in the supported hole of cabinet through bearing, above supported hole
The bottom of box be equipped with one circle gear bits circle, gear bits circle internal diameter be greater than supported hole aperture.
The bearing is double-row self-aligning roller bearing.
Gasket is equipped between bearing holder (housing, cover) upper flanges side and cabinet.
For the present invention using the bearing of the step support tooth shaft upper end in bearing holder (housing, cover), bearing holder (housing, cover) is adjustable through gasket by flange
Tooth shaft axial position meets the axial precision adjustment requirement needed for the engagement adjustment of tooth shaft gear, it is ensured that speed reducer internal gear
Engage the accuracy of mesh adjusted；It being set to outside the supported hole of tooth shaft lower end using gear bits circle, internal diameter is greater than supported hole aperture,
Bearing can be avoided enter into, is damaged when lubricating oil is discharged by the bottom of box by under the impurity such as iron filings granular in lubricating oil gear
Bearing improves greasy property and bearing usage safety performance.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
In figure: cabinet 1, input conical tooth shaft 2, bevel gear 3, vertical gear axis 4, bearing holder (housing, cover) 5, step 6, double-row self-aligning roller
Bearing 7, boring cover 8, gear bits circle 9, supported hole 10.
Specific embodiment
It is described further below in conjunction with drawings and examples.
In Fig. 1: a kind of vertical tooth shaft gear bits lubrication speed reducer of hanging sleeve includes cabinet 1, input conical tooth shaft 2, bevel gear 3, vertical
Formula gear shaft 4, bearing holder (housing, cover) 5, double-row self-aligning roller bearing 7, boring cover 8, gear bits circle 9.The input transmission of conical tooth shaft 2 is placed in cabinet 1
Bevel gear 3 on vertical gear axis 4,4 upper end of vertical gear axis are supported on the platform in bearing holder (housing, cover) 5 through double-row self-aligning roller bearing 7
On rank, 5 upper end of bearing holder (housing, cover) is supported on cabinet through flange and wears connecting bolt encapsulation through boring cover 8；4 lower end of vertical gear axis is through double
Column self-aligning roller bearing is supported in the supported hole 10 of cabinet, and the bottom of box above supported hole is equipped with a circle gear bits circle 9, gear bits
It encloses internal diameter and is greater than supported hole aperture.
On the basis of the above embodiments, gasket can be also added between bearing holder (housing, cover) upper flanges side and cabinet, for finely tuning, such as
The biggish precision adjustment of axial motion is met, then directly replaces bearing holder (housing, cover).
