Abstract
A helical gear gap eliminator, relates to a kind of mechanical device, and described device is comprised of left gear (3) and right gear (4), wide gear (5) and the feather key (6) of axle (1), electromagnet (2), web gear; A gear in meshed gears pair is made wide gear (5), the gear being engaged with is made left gear (3) and the right gear (4) of two web gears, the two axial location of wide gear (5), the left gear of two web gears (3) and right gear (4) are used feather key (6) to be all sleeved on same axis (1); Two gear pairs of three gear formations are close together each other two sides respectively, the one-sided axial shaft shoulder of one of them left gear (3) location.Two gear pairs that this device forms three gears are close together each other two sides respectively, thereby reach, reduce driving error, and reduce vibratory impulse noise contributions.
Description
Technical field
The utility model relates to a kind of mechanical device, particularly relates to a kind of helical gear gap eliminator.
Background technology
On Digit Control Machine Tool, when backlash can cause feed motion reverse, lose command pulse, and produce direction and die, affect machining accuracy, therefore in gear drive, must eliminate gap.
Summary of the invention
The purpose of this utility model is to provide a kind of helical gear gap eliminator, this device is made wide gear by a gear in meshed gears pair, the gear being engaged with is made two web gears, two web gears use feather key to be all sleeved on same axis, two gear pairs that three gears are formed are close together each other two sides respectively, thereby reach, reduce driving error, and reduce vibratory impulse noise contributions.
The purpose of this utility model is achieved through the following technical solutions:
A helical gear gap eliminator, described device is comprised of left gear and right gear, wide gear and the feather key of axle, electromagnet, web gear; A gear in meshed gears pair is made wide gear, and the gear being engaged with is made left gear and the right gear of two web gears, the two axial location of wide gear, and the left gear of two web gears and right gear are used feather key to be all sleeved on same axis; Two gear pairs of three gear formations are close together each other two sides respectively, the one-sided axial shaft shoulder of one of them left gear location.
Described a kind of helical gear gap eliminator, arranges electromagnet on axle one end described in it, and the left gear of two slip web gears in helical gear pair and right gear are close to respectively the teeth groove two sides of wide gear.
Described a kind of helical gear gap eliminator, described in it, axle is web gear, can axial slip.
Advantage of the present utility model and effect are:
1. a gear in the meshed gears pair described in is made wide gear 5, the gear being engaged with is made two web gears 3,4, the two axial location of wide gear, are circumferentially used flat key transmitting torque, and two web gears use feather key 6 to be all sleeved on same axis 1.Two gear pairs that three gears are formed are close together each other two sides respectively, the one-sided axial shaft shoulder of one of them web gear location, another web gear can be under external force along feather key at axial slip, for the helical gear backlash of real-Time Compensation.And simple in structure, be easy to realize, with low cost.
2. this device can arrange electromagnet 2 on web gear axle 1 one end of axial slip, during work, electromagnet is given electricity, produce magnetic field, attract slip web gear 3,4, make two slip gears in helical gear pair be close to respectively the teeth groove two sides of wide gear, reach and eliminate gap effect, while preventing from causing feed motion reverse, lose command pulse, and prevent that direction dies, improve Digit Control Machine Tool machining accuracy.This device can make gear pair teeth groove both sides pretightning force adjustable by adjusting electromagnet current, therefore has the feature that rigidity is large.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing illustrated embodiment, the utility model is described in further detail.
This device is comprised of left gear 3 and right gear 4, wide gear 5 and the feather key 6 of axle 1, electromagnet 2, web gear.
A gear in described meshed gears pair is made wide gear 5, the gear being engaged with is made left gear 3 and the right gear 4 of two web gears, 5 pairs of axial location of wide gear, circumferentially use flat key transmitting torque, the left gear 3 of two web gears and right gear 4 are used feather key 6 to be all sleeved on same axis 1.Two gear pairs that three gears are formed are close together each other two sides respectively, the one-sided axial shaft shoulder of one of them left gear 3 location, another right gear 4 is under external force along feather key 6 at axial slip, for the helical gear backlash of real-Time Compensation.This device can arrange electromagnet 2 on web gear axle 1 one end of axial slip, during work, electromagnet 2 is given electricity, produce magnetic field, attract the right gear 4 of slip web gear 4, make the left gear 3 of web gear of two slips in helical gear pair and the teeth groove two sides that right gear 4 is close to respectively wide gear 5, reach and eliminate gap effect, while preventing from causing feed motion reverse, lose command pulse, and prevent that direction dies, improve Digit Control Machine Tool machining accuracy.This device can make gear pair teeth groove both sides pretightning force adjustable by adjusting electromagnet current, therefore has the feature that rigidity is large.
