A metal shaft ring is a mechanical fastener，It goes around a shaft or pole，Hold it in place with screws or clamps。These devices are used for a variety of functions，From the spacer element on the flagpole to the stop as a drive train。 Metal shaft ring manufacturers usually offer a variety of products，It can also be customized to manufacture parts for special applications where the supply does not work properly for mass production。Available for workers in one and two piece ring designs。 In both cases，Fastening pieces cover the entire shaft，Length and diameter may vary。Most of them are in the form of small rings。The technician can loop the screw through the shaft
Metal washers are generally used to pad workpiece joints，A part that precisely adjusts the clearance of the cushion part。 It can also be used to protect the surface of the connected part from nut abrasion，The pressure exerted by the dispersed nut on the connected piece。 peculiarity： ①Inside and outside diameters，Wide range of thickness options，Thickness optional1mm，2mm，3mm，5mm。 ②Metal gaskets compared to general gaskets，It will not cause the gasket to sag after the connected part is screwed in due to locking，Cause bolt to loosen。 ③Metal gaskets are more common than stamping gaskets，Increase and
Common positioning guide parts include job guide blocks、Locating block、Workpiece fixture、Simple guide parts for welding、Simple guide pin, etc。 Locating pin：Widely used in mold template precision positioning，And other situations that require precise positioning。 Locating block：There is a gap between the guide post and the guide sleeve，Therefore, higher positioning parts are needed to ensure accurate mold closing。 If cavity（Fixed die inserts）And core(Moving die insert)The corresponding positions do not match exactly，Parts such as core inserts and side core-pulling sliders may collide and cause damage or abnormal wear
There are many kinds of conveyors with different styles and structures，For the user，Choosing a suitable conveyor belt is the right choice，The more expensive the machine, the better，The better the fit, the better。 Common belt conveyor、Wire mesh conveying、Plate conveying、Screw conveyor、Chain hook type conveying, etc，To correspond to different transport objects and adopt different transport methods。 1、Climbing belt machine This conveyer is very special，It has specific site requirements，A machine specially designed to transfer materials from the bottom up，Generally used for hillside transfer、Or construction transportation，Through a specialized climb
The positioning pin can simply be understood as a pin used for positioning similar to the index plate structure，As long as its a linear motion with multiple fixed points of demand，And a rotating motion mechanism，Can be applied to the index pin for positioning。 The structure of the index pin is a pin body、Pin head、A combination of a handle and a built-in spring structure。With the diversification of market demand and the diversification of customer demand，Now the positioning pin can be applied to more industries。 Self-locking type：The front end is usually in a prominent state、The front end retracts when the knob is pulled out，It can be locked if it is rotated 90 degrees while remaining pulled out
The precision theory of manipulator has been studied by many scholars，And also came up with a better theory，however，There are still some problems，There are mainly the following aspects： （1）Manipulators under the influence of many factors，Various error sources are often simplified，But a robotic hand is a complex system，The source of error is complicated，therefore，The error model of the manipulator has some deviation from the actual situation。 （2）Static error and dynamic error are considered at the same time，At present, the nonlinear coupling between the two errors still has some difficulties。 （3）At present，
DDmotor，DDisdirect driverBe short for...，Including torque motor and linear motor，Followed by a motor is calledDDDirect drive motor is also called direct drive motor。 Due to its large output torque，Therefore, the product is also directly referred to as torque servo。Different from conventional motors，The high torque of the product allows it to be directly connected to the moving device，Thus eliminating the need for a speed reducer，Gear case，Pulley and other connecting mechanism，Thats why its called a direct-drive motor。 Generally, this type of motor is equipped with a high resolution encoder，So that the product can achieve more than ordinary
Stretch spring struts are mainly used for positioning one end of stretch spring。The position of one end of the stretch spring is defined，The stretching spring can be reset after being stretched。 The specifications of the flow in the market，Available for sale。concrete8paragraph：pass/Groove profile、Half cavity with a slotted groove、Semidentate perforation with flat square、Full perforation with flat square、Unilinear grooved annular grooved semidentate、Unilinear grooved annular grooved holodont、Hexagonal type、Notched pass。Tensile spring struts are mainly usedS45C，SUS303andSUS304Three kinds of materials，Aim atS45CThe surface treatment is a protective film of ferric oxide。
Full name for joint bearing：Radial joint ball bearings or radial spherical plain bearings，We refer to it as a joint bearing，Its structure is simpler than that of rolling bearings，It is a bearing consisting of an inner spherical outer ring and an outer spherical inner ring mounted together，The movement can do small arbitrary Angle rotation swing，Mainly used for low speed operation。 Classification of joint bearings： Joint bearings have been developed for many years，It depends on the different use environment，Evolved into different types，There are specific： Centripetal joint ball bearing，Rod end joint bearing，Thrust angular contact joint bearing。These types are subdivided also
Linear motors generally have flat type、Utype、Tube type。The working system of linear motor is to complete the work through the internal linear guide rail，An environmentally friendly material compresses the coil into a circuit board and connects it to the thermistor，Then a power push is carried out on the rail of the rare earth magnet，It doesnt have to be like a rotating motor，The actuator is fixed on the support frame of the rotating bearing to ensure the stability of the relative moving part，Linear encoder device by direct feedback position，You can measure the load position directly，Thus ensuring the load positionjingDegree of certainty。 See from above，Linear motors do not require intermediate conversion devices，the
