Low -cost hard rock tunnel entry driving machine

Abstract: The utility model discloses a low -cost hard rock tunnel entry driving machine belongs to building engineering machinery technical field, include: cutting / pressure chisel mechanism, actuating system and propulsion support step -by -step system, the actuating system supports a section of thick bamboo, one feeds a section of thick bamboo, single -revolution hydraulic motor, single -revolution gearbox and a slewing bearing including a columniform, the tile bores including a blade disc, a plurality of press wheel and even number piece in cutting / pressure chisel mechanism, blade disc fixed mounting is on slewing bearing's bull gear, press wheel fixed mounting is in on the blade disc, bore the tile installs symmetrically on the blade disc, and every bored on the tile still that the welding has a plurality of to bore teeth. The utility model provides a low -cost hard rock tunnel entry driving machine simple structure, the cost is low, it is very convenient to use, with the rock out volume of minimum rock cutting output maxmizingization, especially in the tunnelling in short distance hard rock tunnel, greatly reduced the energy consumption, improved the efficiency of tunneling, has reduced the tunnel and has tunneled the cost.

Stiffness analysis of slewing bearings

Abstract: The article deals with analysing the stiffness of a special type of bearings called slewing bearings. The purpose of the analysi s is to examine the stiffness of the bearing steel. This type of bearings is most often d signed for operation in which the rolling elements and hence the rings themselves are loaded in the axial direction. However, the aim of the work is not only to examine th stiffness but to identify possible ways that would favourably affect the stif fness, achieving the maximum lifetime or the maximum hours of operation. Stiffne ss measurements will be performed in the Ansys Workbench calculation progra m. On the basis of the measured values, manual calculation will be performed on the basis of which possible inaccuracies that arise from the bearing production i self will be corrected.

It is narrow to rotary device for fork truck

Abstract: The utility model discloses an it is narrow to rotary device for fork truck, it is installed between narrow path fork truck prong and control cabinet, comprising a housin, slewing bearing, the driving gear, first gear, the second gear, the pivot, a plurality of mountings and bearing, the driving gear, first gear, the second gear is connected with three bearing respectively, the bearing passes through the fixed setting of bearing frame in the casing, the mounting includes outer hex bolts, slewing bearing through outer hex bolts with can be connected, the driving gear is connected with motor or motor, the driving gear meshes with first gear mutually, be connected through the pivot between first gear and the second gear, gear mesh outside second gear and slewing bearing's the outer lane, slewing bearing is connected with the fork truck prong. The utility model is used for between fork truck prong and the fork truck control cabinet, relative rotary motion takes place for realization fork truck prong fork truck automobile body relatively, enlarges fork truck's application range, and simple structure, manufacturing convenience have very big market using value simultaneously.

Evaluation of carrying capacity three-row slewing roller bearing

Abstract: Summary: In this paper the numeric model a flexible three-row roller slewing bearing is presented. Characteristic of static carrying capacity with flexibility bearings rings and flexibility their fastening to carrying frames of machines for different kinds fastening screws, bearings clearances and initial clamping have been determinate. Those characteristics with characteristic of capacity for bearing about rigid rings have been compared.

Device for detecting roller way of slewing bearing and detection method of device

Abstract: The invention provides a device for detecting a roller way of a slewing bearing. The device comprises a measuring main machine, a control system and a measuring head and measuring seat system, wherein the measuring main machine comprises a bridge frame, a worktable and a driving system; the bridge frame is arranged on the worktable; the driving system is arranged on the worktable and used for driving the bridge frame; the control system comprises a handle for operating the driving system; and the measuring head and measuring seat system comprises a measuring device for measuring the roller way of the slewing bearing and a data processing system for calculating and counting measured data. The device for detecting the roller way of the slewing bearing is high in measuring accuracy and generality, relatively low in cost and easy to popularize and apply. In addition, the invention provides a detection method of the device for detecting the roller way of the slewing bearing.
