Abstract
The invention provides a worm gear and gear combined pivotal bearing and relates to a pivotal bearing. A retainer (4) is arranged between an outer ring (1) and an inner ring (8), steel balls (3) are arranged in the retainer (4), ball assembling holes are formed in the inner ring (8), ball assembling plugs (6) are arranged in the ball assembling holes and are connected with the inner ring (8) through conical pins (5) arranged on the side face of the inner ring (8), a worm gear (2) is arranged on the outer side face of the outer ring (1), and the worm gear (2) is connected with the outer ring through a set screw (7). The worm gear and gear combined pivotal bearing is high in practicability and relatively convenient to assemble and maintain, the purposes of being bearable for large axial loads, large radial loads and large overturning moment are achieved by transmitting the movement and the power between two spatial cross shafts through worm gear transmission, and the effect of accurate transmission is further achieved.
Description
[technical field]
The present invention relates to a kind of floating bearing, especially relate to a kind of worm-gear toothing combination floating bearing.
[background technique]
Known, at high-precision rotary measurement and control area, conventional floating bearing can carry gear at present, transmit motion and the power between two-parallel axis by gear transmission, it is large that gear transmission has power range, and transmission efficiency is high, peripheral velocity is high, the features such as velocity ratio is accurate, compact structure, this just forms one of conventional type of belt drive; Another floating bearing can carry worm gear, transmit motion and the power between spatial intersecting diaxon by worm drive, worm drive has velocity ratio and (in power transmission, is generally 10 ~ 80 greatly, in indexing system, can reach 600 ~ 1000), stable drive, noise is low, bearing capacity is large, compact structure and can realize the features such as revesal self-locking, more and more applied in specific field, but need measurement and monitoring running precision at any time, the floating bearing of simple function just can not satisfy the demands like this, thereby has restricted the development of enterprise.
[summary of the invention]
In order to overcome the deficiency in background technique, the invention discloses a kind of worm-gear toothing combination floating bearing, the present invention is by arranging worm gear on the outer side surface in floating bearing outer ring, reach and can bear the object of larger axis to load, radial load and tilting moment with this, also there is the object of precision transmission effect simultaneously.
In order to realize described goal of the invention, the present invention adopts following technological scheme:
A kind of worm-gear toothing combination floating bearing, comprise inner ring, outer ring, retainer, steel ball and worm gear, inner ring is arranged in outer ring, between outer ring and inner ring, be provided with retainer, in retainer, be provided with steel ball, on inner ring, be provided with dress ball hole, dress is provided with dress bulb stopper in ball hole, dress bulb stopper is connected with inner ring by the taper pin being arranged on inner ring side, on the outer side surface of outer ring, is provided with worm gear, and worm gear is connected with outer ring by Cock screw.
Described inner ring is inner ring gear.
Described dress ball hole is arranged on the inwall of inner ring, on the inner ring side at dress ball hole place, is provided with pin-and-hole.
Described worm gear and outer ring outer side surface are connected to a fixed, and the junction surface of worm gear and outer ring outer side surface is interference fit, and Cock screw is arranged on the joint of worm gear and outer ring outer side surface, and worm gear is made by bronze material.
Owing to having adopted technique scheme, the present invention has following beneficial effect:
A kind of worm-gear toothing combination floating bearing of the present invention, comprise inner ring, outer ring, retainer, steel ball and worm gear, by worm gear being set on the outer side surface in floating bearing outer ring, reach and can bear the object of larger axis to load, radial load and tilting moment with this, also there is the object of precision transmission effect simultaneously; The present invention is practical, installation and maintenance is all more convenient, operate more convenient, transmit motion and the power between spatial intersecting diaxon by worm drive, worm drive has velocity ratio and (in power transmission, is generally 10 ~ 80 greatly, in indexing system, can reach 600 ~ 1000), stable drive, noise is low, bearing capacity is large, compact structure and can realize the features such as revesal self-locking, more and more applied in specific field.
