齿轮组

Back-up Wrench Group 背钳组 Offered as an option and mounted to the Top Drive Gear Box is a Hydraulic Back-up Wrench Assembly.

被提供作为一选件而安装在顶驱齿轮箱的是一套液压背钳总成，背钳包括一套液压开动的震击器和一条液压伸缩的腿，同时安装在大钳底部的是扶正喇叭口。

The system includes a gearbox (40) and first and second planetary gearset assemblies (42,44) connectable between an output shaft (36) of the motor and a drive shaft (38) of the pump.

该系统包括齿轮箱以及可连接在马达输出轴和泵的传动轴之间的第一和第二行星齿轮组组件。

When none of the sliding gears is in mesh with its countershaft gear, the gears are said to be in neutral.

如果没有变速齿轮组与副传动轴上的齿轮啮合，这时，就叫做空挡。

When designing a gearset one cannot consider torque alone.

设计齿轮组时至考虑扭矩是不够的。

The new style rolling mill has no need of replacement gear wheel group then , physical design cuts down , consumptive material is the machinery that such has improved greatly to controllable nature (3) rolling mill rolling copper coin accuracy short, on old-fashioned rolling mill basis slightly easy to change , to handle conveniently, be that laboratory scientific research has lightened burden , has economized cost under the control of.

新式轧机则不需更换齿轮组，这样大大提高了对轧制铜板精度的可控性（3）本轧机的机械结构设计精简，耗材少，在老式轧机基础上略作改动，方便操作，便于控制，为实验室科研工作减轻了负担，节省了成本。

FA304 and FA318 series and advanced design of the machine, send a reasonable, high precision, low energy consumption, the use of rapid change in the exchange of draft gear group and three on three-under-Ji Chen care under pressure rods hyperbolic new technologies such as drawing, Significantly improve the quality of the cooked.

FA304和FA318系列并条机设计先进，传送合理，精度高，能耗低，采用快速交换变位牵伸齿轮组和三上三下下托式防积尘压力棒双曲线牵伸等新技术，显著提高熟条质量。

When has the vehicles after the caterpillar band, vehicles' kinetic energy transmits through the friction gives the caterpillar band, then drives the gear cluster, finally causes the generator electricity generation.

当有车辆经过履带时，车辆的动能通过摩擦传递给履带，然后带动齿轮组，最后使得发电机发电。

The point contact condition can not only avoid the tooth edge contact, decreases the kinematical errors and vibro-acoustic due to axial misalignments, but also increases the bearing strength of the contact gears.

点接触的接触型态不仅能使齿轮组避免齿缘的接触及降低由轴向组装误差所引起的运动误差和振动噪音，更可增强齿轮的接触强度。

Based on the software Pro/Engineer,the solid model of the increasing speed gear system for wind-power generation is built.

利用三维建模软件Pro/E，建立了风电齿轮增速齿轮组传动系统的实体模型，利用有限元分析软件ANSYS，得到了增速齿轮组的应力和应变规律。

A helical gear is one of the important transmission elements in a machine system and often used for parallel axes gearing.

螺旋齿轮为传动系统中重要机械元件之一，常被使用於平行轴齿轮组上。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
