Abstract
The utility model relates to a rotary support, in the structural type of a bidirectional push bearing, which is characterized in that an upper track of a disk bearing (1) employs a gear (2), a lower track is a lower base (3), a roll groove between the tracks employs a large ball (4), and the middle of the bearing (1) is supported and connected with a crane rotary table (5). The rotary support has reasonable design, reliable operation, simple structure, easy production, long service life, large rotation radius, stable support and larger bearing load.
Description
Technical field
The utility model relates to a kind of mechanical devices, especially is applied to a kind of revolution strut member on the little tonnage hydraulic crane.
Background technology
Existing little tonnage hydraulic crane, often structure is unreasonable for the mechanical devices of the connection bogie that uses on its revolution supporting mechanism, manufacturing cost is also bigger, and is retraining the radius of turn and the hoisting weight of crane work, has influenced the further raising of serviceability.
Summary of the invention
In order to improve the serviceability of little tonnage hydraulic crane, the utility model provides a kind of revolution strut member, after it is applied to little tonnage hydraulic crane, the crane radius of turn is strengthened, and revolution is steadily free, and hoisting weight increases.
The technical solution of the utility model is to provide a kind of revolution strut member, the version of employing two-direction thrust bearing, it is characterized in that: the last raceway of disc bearing 1 adopts gear 2, following raceway is a lower bottom base 3, and the slot rolling between raceway adopts big ball 4, and the midship mounting of bearing 1 links bogie 5.
During work, the revolution strut member is under the hydraulic power effect, and last raceway and bogie link together and can realize that 360 ° of freedom in the plane steadily rotate, and following raceway and crane base are fixed together, and keeps its relative stablizing.
Characteristics of the present utility model are: this revolution strut member, and reasonable in design, reliable operation; Simple in structure, easily manufactured, long service life; Radius of turn is big, supports steadily, can bear bigger load.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of an embodiment of the utility model revolution strut member.
Among the figure: 1, bearing; 2, gear; 3, lower bottom base; 4, big ball; 5, bogie.
The specific embodiment
As shown in Figure 1, be applied to a embodiment on the 3T fully automatic hydraulic crane revolution supporting mechanism for the utility model: revolution strut member is a disc, the version of employing two-direction thrust bearing, thickness 60-80MM, external diameter 900-1000MM.The last raceway of disc bearing 1 adopts gear 2, and following raceway is a lower bottom base 3, and the slot rolling between raceway adopts big ball 4, and the midship mounting of bearing 1 links bogie 5.
During work, the revolution strut member is under the hydraulic power effect, and last raceway and bogie link together and can realize that 360 ° of freedom in the plane steadily rotate, and following raceway and crane base are fixed together, and keeps its relative stablizing.
This revolution strut member, reasonable in design, reliable operation; Simple in structure, easily manufactured, long service life; Be applied on the 3T fully automatic hydraulic crane, need not add counterweight in the lifting height 7m, radius of turn is big, supports steadily, can bear bigger load.
Claims (1)
1. one kind is turned round strut member, adopt the version of two-direction thrust bearing, it is characterized in that: the last raceway of disc bearing (1) adopts gear (2), and following raceway is lower bottom base (3), slot rolling between raceway adopts big ball (4), and the midship mounting of bearing (1) connects bogie (5).
