Abstract
The utility model discloses a rotating support used of an excavator, comprising an inner ring and an outer ring, wherein the outer ring is sheathed at the outer side of the inner ring; a ring-shaped rollway is arranged between matching surfaces of the outer ring and the inner ring; a plurality of steel balls which are arranged in a ring shape along the rollway are evenly distributed in the ring-shaped rollway; a ring-shaped groove which is positioned at the outer side of the ring-shaped rollway is also arranged between the matching surfaces of the outer ring and the inner ring; the ring-shaped groove is internally provided with matched ring-shaped sealing strips; the outer side of the outer ring comprises an oil nozzle with a pipeline; and the inner wall of the inner ring is provided with a tooth ring. The rotating support is characterized in that the tooth top of the tooth ring on the inner wall of the inner ring is a ring-shaped slope surface. In the utility model, included angles of the chamfered surfaces of the upper gear and the lower gear on the inner wall of the inner ring and the horizontal surface are different so as to lead the matching of a pinion gear and a main gear of the excavator to be closer, thus avoiding the phenomenon of tooth jumping between the pinion gear and the main gear occurs.
Description
Technical field
The utility model relates to a kind of pivoting support field, is specifically related to a kind of excavator and uses the pivoting support field.
Background technology
Pivoting support is used very extensive in real industry, be called by people: " joint of machine ", it is mainly used in being widely used in: automobile crane, locomotive crane, portal crane, ship's crane, crane for steelworks use, container crane, excavator, bottle placer and CT machine standing wave therapeutic equipment, nautical instrument, radar antenna base, missile launcher, tank, robot and revolving restaurant or the like aspect.
Excavator generally all is unanimous between the higher and lower levels with the angle of the gear chamfering face horizontal plane of pivoting support, horizontal by 45 °, in pinion and gear wheel engagement, because excavator is when work, make pinion and gear wheel engagement place at tooth, produce certain angle, and the non-datum tooth top of gear wheel part intensity is the most weak, spring tooth phenomenon in use always occurs.
The utility model content
The technical problems to be solved in the utility model provides a kind of excavator pivoting support, and its inner ring up and down angle of two gear chamfering faces and horizontal plane is inequality, makes excavator in the course of the work, avoids the phenomenon of its pinion and gear wheel generation spring tooth.
For addressing the above problem, the technical solution of the utility model is:
A kind of excavator pivoting support, include inner ring and outer ring, the outer ring is enclosed within the inner ring outside, include ring raceway between the fitting face of outer ring and inner ring, be distributed with a plurality of steel balls in the ring raceway along the raceway circular array, also include the annular groove that is positioned at the ring raceway outside between the fitting face of outer ring and inner ring, be provided with the annular sealing strip that is complementary in the annular groove, the outside of outer ring includes the oil nozzle that has pipeline, the inwall of inner ring is provided with gear ring, and the upper and lower end face of the inwall upper ring gear of inner ring respectively is provided with one section annular ramp face; The annular ramp surface chamfer of the upper surface of inner ring inwall upper ring gear is 37 °, and the annular ramp surface chamfer of lower surface is 45 °.
The beneficial effects of the utility model:
Tooth on the utility model inner ring inwall up and down angle of two fillet surfaces and horizontal plane is inequality, makes to cooperate closelyr between pinion and the gear wheel of excavator, has avoided the phenomenon of pinion and gear wheel generation spring tooth.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, a kind of excavator pivoting support, include inner ring 1 and outer ring 2, outer ring 2 is enclosed within inner ring 1 outside, include ring raceway 3 between the fitting face of outer ring 2 and inner ring 1, be distributed with a plurality of steel balls 4 in the ring raceway 3 along the raceway circular array, also include the annular groove 5 that is positioned at the ring raceway outside between the fitting face of outer ring 2 and inner ring 1, be provided with the annular sealing strip 6 that is complementary in the annular groove 5, the outside of outer ring 2 includes the oil nozzle 7 that has pipeline, the inwall of inner ring 1 is provided with gear ring, and the upper and lower end face of the inwall upper ring gear of inner ring 1 respectively is provided with one section annular ramp face, and annular ramp face 8 chamferings of the upper surface of inner ring inwall upper ring gear are 37 °, it highly is L, be 2m, m is a module, and the annular ramp surface chamfer of lower surface 9 is 45 °.
Claims (2)
1. excavator pivoting support, include inner ring and outer ring, described outer ring is enclosed within the inner ring outside, include ring raceway between the fitting face of described outer ring and inner ring, be distributed with a plurality of steel balls in the described ring raceway along the raceway circular array, also include the annular groove that is positioned at the ring raceway outside between the fitting face of described outer ring and inner ring, be provided with the annular sealing strip that is complementary in the described annular groove, the outside of described outer ring includes the oil nozzle that has pipeline, the inwall of described inner ring is provided with gear ring, it is characterized in that: the upper and lower end face of the inwall upper ring gear of described inner ring respectively is provided with one section annular ramp face.
