Abstract

A bevel gear transmission gap eliminating device relates to mechanical devices and is characterized by being composed of a shaft (1), a bevel gear (2), a shaft end blocking plate (3), screws (4), a shaft (5), a sliding bevel gear (6), a flat key (7) and an electromagnet (8); the two bevel gears are respectively arranged on the two cross arrangement stepped shafts (1) and (5) and connected through the flat key, the bevel gear (2) is biaxially positioned, and the electromagnet is arranged at the shaft end of the axially-sliding bevel gear (6) . According to the bevel gear transmission gap eliminating device, the electromagnet is arranged at the axially-sliding shaft end, and the electromagnet supplies power during working for generating a magnetic field for further magnetizing the sliding bevel gear, so that closely fitting of a gear pair can be obtained to eliminate the gap; the advantages of gap compensation at any time and high rigidity can be achieved so as to reduce transmission errors and vibration and impact noise.

Description

Bevel Gear Transmission gap eliminator
Technical field
The present invention relates to a kind of mechanical device, particularly relate to a kind of Bevel Gear Transmission gap eliminator.
Background technology
When backlash can cause feed motion reverse on Digit Control Machine Tool, 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 Bevel Gear Transmission gap eliminator, this device arranges electromagnet at axle head that can axial slip, when work, electromagnet is given electricity, produces magnetic field, attracts shifting slide gear, make gear pair laminating closely, reach and eliminate gap effect, there is gap and compensate at any time, the feature that rigidity is large, 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:
Bevel Gear Transmission gap eliminator, described device is made up of axle, bevel gear, axle end baffle plate, screw, axle, slippage bevel gear, flat key and electromagnet; Two gears lay respectively at the multidiameter of two arranged crosswise and upper, and connect by flat key, the wherein two axial location of bevel gear, and gear shaft terminal that can axial slip arranges electromagnet.
Advantage of the present invention and effect are:
1. gear 6 axially can slippage under electromagnetic force, for compensating gear-driven backlash, while preventing from causing feed motion reverse, loses command pulse, and produces direction and die, and affects machining accuracy, and simple in structure, is easy to realize, with low cost.
2. this device arranges electromagnet 8 at axle 5 ends that can axial slip gear 6, when work, electromagnet is given electricity, produce magnetic field, attract shifting slide gear 6, make gear pair laminating closely, reach the gap effect of eliminating, having gap compensates at any time, the feature that rigidity is large, reduces driving error thereby reach, and reduces vibratory impulse noise contributions.
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 axle 1, bevel gear 2, axle end baffle plate 3, screw 4, axle 5, slippage bevel gear 6, flat key 7 and electromagnet 8.
Two gears lay respectively on the multidiameter 1 and 5 of two arranged crosswise, and connect by flat key, transmitting torque, and wherein 2 pairs of axial location of bevel gear, another gear 6 axially can slippage.Be used for compensating gear-driven backlash, while preventing from causing feed motion reverse, lose command pulse, and produce direction and die, affect machining accuracy.
This device arranges electromagnet at gear shaft terminal that can axial slip, when work, electromagnet is given electricity, produce magnetic field, attract shifting slide gear, make gear pair laminating closely, reach the gap effect of eliminating, having gap compensates at any time, the feature that rigidity is large, reduces driving error thereby reach, and reduces vibratory impulse noise contributions.
