0R/T83502003/S01977.2090
This standard defines the solid machine hollow pins for light auxiliary transmission and mechanized transmission, Evaluation, technical characteristics of roller sprockets with edge and matching sprockets and accessories: The chain size specified in the standard will ensure the compatibility of the chain and the shoe section on the same day. This standard applies to sprockets with teeth from 6 to 40. The requirements for the sprocket are to ensure that it is compatible with the chain and the shoe section under normal use conditions. Method: The first condition is the design of these wheels. The standard also stipulates the size of K-type accessories and modified high-energy plates. 2 Normative reference documents Many of the two documents in the standard have become the effect of this standard due to the use of wooden cups on time. All the cited books after the period of time are Parts, their subsequent replacement orders (excluding errata) or revisions are not applicable to this standard, however: the latest versions of these documents can be used in conjunction with the agreement reached based on this standard.

Jiechen is a theoretical ruler, which is used to calculate the length and thickness of silicon wheel: instead of a ruler that is used to make lighter festivals. The table shows the main dimensions, test force and tensile strength of hollow shaft conveyor chain. The length of the chain is the theoretical reference size, which is used to calculate the chain length, not the length of the chain that exceeds the limit. b
The shaded area is the light section specification, the chain section size determines the length of the material plate for the small limit of the section of the platinum machine 3.3 tensile strength
The total length is 3 meters
Hollow pin
Small wave
The test chain has 3 virtual self-dimensional sections. The two ends of the chain should be connected to the test machine head, and the pin chain hole is connected to the test hole. The test head should be set to be non-selective universal movement. The actual trial production method should be based on the system. When the failure occurs at the connection with the chuck, the test is invalid.
3.4 Length
3.4.1 The initial measurement of chain length should be in accordance with 3.4.2.3.4.5 and 3.4. The view is: the length of the finished chain should be the relative nominal size +,
Note: The needle device of the downward transmission should be the product body negotiated between the user and the manufacturer, 3.4.2 Standard measurement length
The measured length of the chain should be close to 30m. The number of pitches is the quotient. The end of the chain should be the inner link, 3.4.3 Support
The support card is supported by the medical device in the slight installation. 3.4.4 Measurement or force
The measurement should be effective for the product, according to Table 1 and Table 2. 3.5 What is the standard for the wrench hoop? - When the velvet strips are closed in the market, it is necessary to use a pressure plate to avoid the joints (see Figure 11 and Figure 1): The size of the bending chain link is determined in the table: and Table 2,
3.6 marking
The markings in this table are based on the principles of Table 1 and Table? The minimum strength (the value that can be produced is M when it indicates a solid pin chain, and M when it indicates a hollow pin chain. GB/T8350-2003/1S01977;200
Example: Mc indicates a solid pin chain, and its tensile strength is 8CV. MC224 indicates a hollow pin chain, and its tensile strength is 221kN. The letters B, F, P, and S represent titanium bars respectively. Internal smooth type: that is, pre-cast, with edge deep needle, large roller and small roller chain, the number following it indicates the pitch of the chain rm?.
Example: MC224-F-200 means that the chain is equipped with a belt roller, and the pitch is 2namm. 3.7 Marking
The chain should have a special manufacturer's name or trademark, and also be marked with the average chain number listed in Table or Table 2 4 Accessories

For even-numbered sprockets, the measurement method is to place the two measuring rods matching the sprocket on the two teeth corresponding to the radial direction of the sprocket. For odd-numbered sprockets, the measurement method is to place the two measuring rods matching the sprocket on the closest teeth. Near the two corresponding teeth in the direction of the wheel straight price, the measurement list is violated.

5.2 Sprocket tooth shape
5.2.1 Overview
The tooth type and shape should be based on 2. 2.~2.1 of the specification (see Figure 5) 5.2.2 Working surface
1 is the area between the teeth and the work surface, one of which is the center of the work surface and the other is located at the center of the work surface. The working surface is the effective working belt of the tooth shape. This is not limited by the tooth height, which makes this area smaller. Please refer to Figure 5.2. The working surface can be a point or a convex surface. 5.2.3 Pressure angle
5 The pressure angle is the angle formed between the normal of the contact point of the working surface and the contact point of the work surface. The maximum contact angle at any contact point on the working surface is the same as that in Table 5.
