Abstract
The utility model relates to a hole involute gear. The gear of the original involute gear is provided with the gear transmission of various holes in the condition without special devices and high technology. The hole can be a through hole or a half through hole and the shape can be circle, elliptical, etc. The utility model has an obvious effect on increasing the gear flexibility, improving the tooth surface lubrication, decreasing the vibration and reducing the noise. The vibration can be reduced by 40 to 130 mv and the noise can be reduced by 2 to 8 decibels in general.
Description
The utility model hole involute gear is a kind of gear drive, belongs to mechanistic category.Specifically, be exactly a kind of increase gear teeth flexibility of on the gear teeth of gear, opening various holes, reduce the gear transmission of vibration, reduction noise and flank of tooth temperature.
At present, the gear teeth of domestic and international known involute gear are entity, but lubricated in order to improve, reduce vibration, in disclosed document, also mentioned perforate on gear pump, valve, nozzle.The technological scheme of perforating on the gear shaft.Though it has widely used advantage for involute gear, mostly exist the defective that intensity is low, the life-span is short, noise is high, vibration is big.
In sum,, improve gear teeth flexibility simultaneously, a kind of technological scheme of opening the involute gear in different holes, cave on the gear teeth of involute gear is provided for overcoming involute gear noise height, vibrating the defective big, that the oily temperature of the flank of tooth is high.
The utility model hole involute gear, be a kind of under the prerequisite that need not special equipment and high technology, promptly on the gear teeth of original involute gear,, open a kind of gear transmission in the hole of different shape and size according to different technical characteristicss and requirement with general boring method.
The hole of the utility model hole involute gear can be that the hole type is that half through hole type (as Fig. 1, shown in 2) can also be through hole type (as Fig. 1, shown in 3).
The hole shape of the utility model hole involute gear is generally circle and ellipse.
The hole diameter of the utility model hole involute gear and the degree of depth and hole center height can decide according to the size dimension of gear teeth width B and normal module Mn, and its parameter is:
The hole type i.e. half through hole type:
Hole degree of depth L
1=L
2=(0.25～0.3) B
Hole center height h
1=(0.9～1) Mn
The hole diameter phi
1=φ
2=(0.5～0.7) Mn
The through hole type:
Hole degree of depth L=B
Hole center height h
2=(0.9～1) Mn
Hole diameter phi=(0.5～0.7) Mn
The optimum implementation of the utility model hole involute gear is: the hole type i.e. half through hole type: as involute gear teeth width B=70mm, the hole of opening during normal module Mn=6mm is of a size of: hole degree of depth L
1=L
2=20mm, hole center height h
1=5.4mm, the hole diameter phi
1=φ
2=3mm.
The through hole type: as involute gear teeth width B=50mm, the hole of opening during normal module Mn=6mm is of a size of: hole degree of depth L=B=50mm, hole center height h
2=6mm, hole diameter phi=3mm.
It is very remarkable in rotating speed h that the utility model involute gear with apertures reduces vibration1=700～1400r. Drop-out value is △ aX40～130MV in the P.M scope. Noise also has obvious reduction, at rotating speed h1=600～1200r.P.M reducing noise value is that 2～8 decibels of flank of tooth temperature controls of △ d β ≈ are at 45～50 ℃. So the utlity model has certain promotional value and economic benefit and social benefit.
