Tree mover soil gauge ball style accuse device

Abstract: The utility model discloses a tree mover soil gauge ball style accuse device, including the inside and outside pole of slewing bearing frame, knife rest and looks suit, the one end fixed connection of interior pole is in one side of knife rest, and the inside fixed mounting of the interior pole other end has the nut, and the spiral shell has closed the lead screw in the nut, and the front end of lead screw extends from interior pole, outer pole rotates to be installed on the solid of revolution of slewing bearing shelf location, is equipped with the locating hole on the outer pole, is equipped with one row of locating hole on the interior pole, has the locating pin to pass locating hole on corresponding locating hole and the one row of locating hole in proper order and be in the same place inside and outside pole is fixed. The utility model discloses it is rational in infrastructure, pull out the locating pin, the lead screw rotates for interior pole can freely stretch out and draw back along outer pole, thereby makes the interval between slewing bearing frame and the knife rest adjustable, and then the specification of adjustable native ball, has guaranteed the working range of tree mover.

Maintenance-free dry running slewing bearing structure for sun tracking

Abstract: The invention discloses a maintenance-free dry running slewing bearing structure for sun tracking. The maintenance-free dry running slewing bearing structure for sun tracking comprises a shell, a drive motor as well as a worm and a worm gear which are arranged in the shell and mutually engaged, wherein a left gland and a right gland are arranged on the shell corresponding to the two ends of the worm; a left stepped slide bush and a right stepped slide bush which are manufactured from an engineering plastic are arranged between the left gland and the worm, and between the right gland and the worm respectively; the left stepped slide bush and the right stepped slide bush are in close fit with the corresponding left gland and right gland respectively to form an integrated structure; the inner walls of the left stepped slide bush and the right stepped slide bush are bonded with the worm, and the worm is capable of rotating relative to the left stepped slide bush and the right stepped slide bush; and a composite layer is injected on a thread surface of the worm or the worm gear by virtue of the engineering plastic. According to the maintenance-free dry running slewing bearing structure for sun tracking disclosed by the invention, a maintenance-free dry running design is carried out on a slewing bearing for sun tracking through analysis for the running modes of a sun tracker and by combining the features of modern engineering plastics and composite technologies, so that the slewing bearing thoroughly gets rid of the problem of lubrication failure, and the long-time reliable running of the slewing bearing is ensured.

Wind power generator

Abstract: The utility model relates to a wind generator, belonging to the generator field. The wind generator is characterized in that a slewing bearing is mounted on a front lateral wall hole of a chassis, a hub is connected with the front lateral wall of the chassis through the slewing bearing, the hub penetrates through the slewing bearing to be connected with one end of a flexible coupling, and the other end of the flexible coupling is connected with a gear box. The hub of the wind generator is fixed on the chassis of the generator through the slewing bearing, and is connected with the gear box via flexible connection. The direct wind thrust can be avoided to directly affect the gear box through the flexible connection, thereby guaranteeing the normal operation of the gear box, and simultaneously reducing the axial size of the wind generator.

Miniature caterpillar hydraulic excavator frame

Abstract: The utility model discloses a miniature track type hydraulic excavator frame comprising a upper frame, a lower frame and a slewing bearing The lower frame is welded by a X frame, a left and a right tracks box and a bearing roller support The left and right tracks are respectively arranged on both sides of the X frame The bearing roller support is respectively arranged on the left and right track box The upper frame and the lower frame are connected through the slewing bearing The characteristics are that the out ring of the upper frame and the slewing bearing are connected through the locating pin The inner ring of the lower frame and the slewing bearing are connected through the bolt The track box adopts the asymmetric reversing shape of 'u' structure with a 'v' shaped top The X frame is a four-plate typed welded struture The bearing roller shapes like 'L' The main frame vertical beam of the upper frame shapes like'T' and is butt welded by a cross plate and an opposite plate The utility model not only has a beautiful appearance, a high strength and a high stiffness but also has a fine manufacturability, a low cost therefore is an ideal a miniature track type hydraulic excavator frame

Novel four-point contact ball-type slewing ring bearing

Abstract: The utility model relates to a novel four-point contact ball-type slewing ring bearing applied to a gamma knife operating board In the utility model, the raceway form of the traditional four-point contact ball-type slewing ring bearing is changed; normally, the raceway of a ball bearing takes the shape of a peach, however, the raceway of the bearing in the utility model is designed to be V-shaped Therefore, noises are greatly lowered, and the starting torque is reduced by half, and the utility model satisfies the use requirement and has a wide market prospect
