Abstract

The invention discloses a bevel gear gap elimination device, and relates to a mechanical device. The device consists of a shaft (1), an electromagnet (2), a left web gear (3), a right web gear (4), a wide gear (5) and a sliding key (6), wherein a gear in meshed gear pairs is machined into the wide gear (5), and gears meshed with the wide gear (5) are machined into the left web gear (3) and the right web gear (4); the wide gear (5) is biaxially positioned; the left web gear (3) and the right web gear (4) are arranged on the same shaft (1) through the sliding key (6) in a sleeving way; the two gear pairs formed by the three gears cling to each other on two lateral surfaces respectively; the left web gear (3) adopts one-sided axial shaft shoulder positioning. According to the device, the two gear pairs formed by the three gears cling to each other on two lateral surfaces respectively, so that effects of reducing transmission errors and lowering vibration and impact noise are achieved.

Description

A kind of helical gear gap eliminator
Technical field
The present invention relates to a kind of mechanical device, particularly relate 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 object of the present invention is to provide a kind of helical gear gap eliminator, wide gear made by a gear in meshed gears pair by this device, 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, reduce driving error thereby reach, and reduce vibratory impulse noise contributions.
The object of the invention is to be achieved through the following technical solutions:
A kind of helical gear gap eliminator, described device is made up of left gear and right gear, wide gear and the feather key of axle, electromagnet, web gear; A gear in described meshed gears pair is made wide gear, the gear being engaged with is made left gear and the right gear of two web gears, the two axial location of wide gear, the left gear of two web gears and right gear use 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, describedly can arrange electromagnet on web gear axle one end of axial slip, 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.
Advantage of the present invention 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, when 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.
Brief description of the drawings
Fig. 1 is overall structure schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing illustrated embodiment, the invention will be further described.
This device is made up 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 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 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, when 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 right gear 4 be close to respectively the teeth groove two sides of 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.
