1. Yes, helix angle β Take the size of 20 °～ twenty-five °
ordinary spur gears are meshed along the tooth width at the same time, resulting in impact vibration noise and unstable transmission. The helical gear transmission is better than the straight gear transmission, and it can close the center distance for high speed and heavy load
the larger the helix angle is, the greater the coincidence is, which is more concive to the smooth movement and the rection of noise. Everything is two-sided. Although increasing the helix angle brings many advantages, the axial force generated ring the work is also increased, so the size of the helix angle should depend on the quality requirements and processing accuracy of the work, generally 8-25, The larger value can be taken according to the situation< Extended data:
when the gear mechanism of cylindrical gear is meshing and driving, there is a large tangential relative sliding speed along its tooth length direction, so it will proce a large rate of friction and wear
on the other hand, the tooth profiles of the two wheels are in point contact state, and the contact stress value is very large, which causes the surface to be pressed and fed prematurely, and aggravates the tooth wear. Compared with parallel axis helical gear, the performance of staggered axis helical gear mechanism is better

2. Fire coin global is scheled to open UTK / BTC and UTK / eth transactions in the Innovation Zone at 15:00 Beijing time on January 18, 2017.
3. Fire coin global is scheled to launch utrust (UTK) on January 17, 2017 Beijing time. The recharge service was opened at 14:30 on January 17, 2017. At 14:30 on January 19, 2017, UTK cash withdrawal business was opened.
4. UIM card generally refers to China Telecom mobile card, which is mainly used for making calls; UTK card generally refers to the wireless network card, mainly used for Internet access. To learn more about service offers, click the "official website" customer service 217 below to answer for you.
5. Hello, UIM card generally refers to China Telecom mobile card, which is mainly used for making calls
UTK card generally refers to wireless network card, which is mainly used for Internet access.

6. UTK is the abbreviation of universal testing kit, which is the general middleware to build various microcomputer controlled testing machine systems, including the measurement and control drive software of microcomputer end and the front-end electromechanical control hardware. According to the platform, UTK can be divided into two categories: PC based (UTK on PC) and embedded (UTK embedded). The former is suitable for medium and high-end desktop host system, while the latter is suitable for economical host and portable system.
7. UTK UIM card (also known as OTA card) is an enhanced UIM card, which can provide more value-added services. The current OTA smart card, with 64K capacity, supports 250 phonebooks and 50 SMS storage functions; Preset rich and colorful value-added services, which can provide SMS, call and service services; You can download and update business at any time through the over the air download function to create a personalized menu. Thank you for your attention to telecom procts and wish you a happy life.

8. UTK card 64K and UIM card 128K are different in the number of telephone entries and information, that is, the capacity of the card is different
1. UTK is the abbreviation of "UIM card tool kit", which means "UIM card development kit". In order to use additional value-added services of mobile phone (such as Unicom Telecom), it is required to replace the ordinary UIM card of mobile phone with UTK UIM card. UTK can be understood as a small programming language for developing value-added services. It allows the user identification mole (UIM) based on smart card to run its own application software. UTK technology provides a developable environment for the value-added services of UIM card, which is a simple and easy to operate development platform
UTK card is a user identification card for CDMA network, which adopts the machine card separation technology initiated by China Unicom International. At present, it is mainly used in PHS and CDMA mobile phones operated by China Telecom
2. The UIM card is used to access the CDMA network of China Telecom and is the identification of the access network system. The card stores the necessary data of the access network, such as UIM ID, authentication data aky value, IMSI number, etc. UIM (user identify mole) user identification mole. It is a kind of smart card applied in cdmaOne mobile phone, which can be inserted into the corresponding 2G mobile phone to use mobile phone service. The standardization of UIM card is carried out by 3GPP2.
